[ Upstream commit 19c624c6b29e244c418f8b44a711cbf5e82e3cd4 ]

This commit corrects max and step values for v4l2 control for
V4L2_CID_JPEG_RESTART_INTERVAL. Max should be 0xffff and step should be 1.
It was found by using v4l2-compliance tool and checking result of
VIDIOC_QUERY_EXT_CTRL/QUERYMENU test.
Previously it was complaining that step was bigger than difference
between max and min.

[ Upstream commit 57b26497fabe1b9379b59fbc7e35e608e114df16 ]

ib_dma_map_sg() augments the SGL into a 'dma mapped SGL'. This process may
change the number of entries and the lengths of each entry.

Code that touches dma_address is iterating over the 'dma mapped SGL' and
must use dma_nents which returned from ib_dma_map_sg().

ib_sg_to_pages() and ib_map_mr_sg() are using dma_address so they must use
dma_nents.

[ Upstream commit 2a4daadd4d3e507138f8937926e6a4df49c6bfdc ]

Older versions of Libreboot and Coreboot had an invalid value
(`3' in my case) in the century byte affecting the GM45 in
the Thinkpad X200.  Not everybody's updated their firmwares,
and Linux <= 4.2 was able to read the RTC without problems,
so workaround this by ignoring invalid values.

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit 1f7698abedeeb3fef3cbcf78e16f925df675a179 ]

The current code assigns the reference, and then goes to increment
it if the toggle bit has changed. That way, we get

Toggle  0  0  0  0  1  1  1  1
ID      1  1  1  1  1  2  2  2

Fix that by assigning the post-toggle ID to get

Toggle  0  0  0  0  1  1  1  1
ID      1  1  1  1  2  2  2  2

[ Upstream commit 6e88098ca43a3d80ae86908f7badba683c8a0d84 ]

When building without CONFIG_HW_RANDOM_PPC4XX, I hit the following build failure:
drivers/crypto/amcc/crypto4xx_core.c: In function 'crypto4xx_probe':

This patch fix the needed argument of ppc4xx_trng_probe()/ppc4xx_trng_remove() in that case.

Currently the call to cdev_add is missing a check for failure. Fix this by
checking for failure and exiting via a new error path that ensures the
allocated comp_channel struct is kfree'd.

Fix fixed_phy not checking GPIO if no link_update callback
is registered.

In the original version all users registered a link_update
callback so the issue was masked.

[ Upstream commit e42280886018c6f77f0a90190f7cba344b0df3e0 ]

Shifting a u8 by 24 will cause the value to be promoted to an integer. If
the top bit of the u8 is set then the following conversion to an unsigned
long will sign extend the value causing the upper 32 bits to be set in
the result.

Fix this by casting the u8 value to an unsigned long before the shift.

Detected by CoverityScan, CID#1309693 ("Unintended sign extension")

In remove(), use cancel_delayed_work_sync() to cancel the
delayed work. Otherwise there's a chance that this work
will continue to run until after the device has been removed.

This issue was detected with the help of Coccinelle.

[ Upstream commit 1a67356e9a4829da2935dd338630a550c59c8489 ]

It is wrong to use bio->bi_vcnt to figure out how many segments
there are in the bio even though CLONED flag isn't set on this bio,
because this bio may be splitted or advanced.

So always use bio_segments() in blk_recount_segments(), and it shouldn't
cause any performance loss now because the physical segment number is figured
out in blk_queue_split() and BIO_SEG_VALID is set meantime since
bdced438acd83ad83a6c ("block: setup bi_phys_segments after splitting").

pci_map_rom/pci_get_rom_size() performs memory access in the ROM.
In case the Memory Space accesses were disabled, readw() is likely
to trigger a synchronous external abort on some platforms.

In case memory accesses were disabled, re-enable them before the
call and disable them back again just after.

[ Upstream commit 3e5daee5ecf314da33a890fabaa2404244cd2a36 ]

Using dma_dev->dev for mappings before it's assigned with the correct
device is unlikely to work as expected, and with future dma-direct
changes, passing a NULL device may end up crashing entirely. I don't
know enough about this hardware or the mv_xor_prep_dma_interrupt()
operation to implement the appropriate error-handling logic that would
have revealed those dma_map_single() calls failing on arm64 for as long
as the driver has been enabled there, but moving the assignment earlier
will at least make the current code operate as intended.

[ Upstream commit 13649101a25c53c87f4ab98a076dfe61f3636ab1 ]

Currently, the expression for calculating RON is always going to result
in zero no matter the value of ram->mr[1] because the ! operator has
higher precedence than the shift >> operator.  I believe the missing
parentheses around the expression before appying the ! operator will
result in the desired result.

[ Note, not tested ]

when exec is false and nvkm_pmu_send has not updated the array. Avoid
confusion by only dumping out these values if they have been actually

The apq8016 driver leaves the of-node refcount at aborting from the
loop of for_each_child_of_node() in the error path.  Not only the
iterator node of for_each_child_of_node(), the children nodes referred
from it for codec and cpu have to be properly unreferenced.

In the rare and unsupported case of a hostname list nfs_parse_devname
will modify dev_name.  There is no need to modify dev_name as the all
that is being computed is the length of the hostname, so the computed
length can just be shorted.

Fix a soft lockup when NFS client delegation recovery is attempted
but the inode is in the process of being freed. When the
igrab(inode) call fails, and we have to restart the recovery process,
we need to ensure that we won't attempt to recover the same delegation
again.

From: Chen-Yu Tsai <wens@csie.org>

[ Upstream commit e7e7e0d7beafebd11b0c065cd5fbc1e5759c5aab ]

If the clock tree is not fully populated when the timer-sun5i init code
is called, attempts to get the clock rate for the timer would fail and
return 0.

Make the init code for both clock events and clocksource check the
returned clock rate and fail gracefully if the result is 0, instead of
causing a divide by 0 exception later on.

From: Marek Szyprowski <m.szyprowski@samsung.com>

[ Upstream commit ca70ea43f80c98582f5ffbbd1e6f4da2742da0c4 ]

MCPM does a soft reset of the CPUs and uses common cpu_resume() routine to
perform low-level platform initialization. This results in a try to install
HYP stubs for the second time for each CPU and results in false HYP/SVC
mode mismatch detection. The HYP stubs are already installed at the
beginning of the kernel initialization on the boot CPU (head.S) or in the
secondary_startup() for other CPUs. To fix this issue MCPM code should use
a cpu_resume() routine without HYP stubs installation.

This change fixes HYP/SVC mode mismatch on Samsung Exynos5422-based Odroid
XU3/XU4/HC1 boards.

From: Steve Sistare <steven.sistare@oracle.com>

[ Upstream commit 31b6a05f86e690e1818116fd23c3be915cc9d9ed ]

megaraid_sas takes 1+ seconds to load while waiting for firmware:

[2.822603] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state
[3.871003] megaraid_sas 0000:03:00.0: FW now in Ready state

This is due to the following loop in megasas_transition_to_ready(), which
waits a minimum of 1 second, even though the FW becomes ready in tens of
millisecs:

        /*
         * The cur_state should not last for more than max_wait secs
         */
        for (i = 0; i < max_wait; i++) {
                ...
                msleep(1000);
        ...
        dev_info(&instance->pdev->dev, "FW now in Ready state\n");

This is a regression, caused by a change of the msleep granularity from 1
to 1000 due to concern about waiting too long on systems with coarse
jiffies.

To fix, increase iterations and use msleep(20), which results in:

[2.670627] megaraid_sas 0000:03:00.0: Waiting for FW to come to ready state
[2.739386] megaraid_sas 0000:03:00.0: FW now in Ready state

[ Upstream commit 5ac188b12e7cbdd92dee60877d1fac913fc1d074 ]

If riocm_get_channel() fails, then we should just return -EINVAL.
Calling riocm_put_channel() will trigger a NULL dereference and
generally we should call put() if the get() didn't succeed.

[ Upstream commit 201676095dda7e5b31a5e1d116d10fc22985075e ]

The "cpu" variable comes from the sscanf() so Smatch marks it as
untrusted data.  We can't pass a higher value than "nr_cpu_ids" to
cpu_possible() or it results in an out of bounds access.

[ Upstream commit a3d7f22ef34ec4206b50ee121384d5c8bebd5591 ]

Checking of kmalloc() seems to have been committed - as
cx23885_dvb_register() is checking for != 0 return, returning
-ENOMEM should be fine here.  While at it address the coccicheck
suggestion to move to kmemdup rather than using kmalloc+memcpy.

[ Upstream commit a5fdd713d256887b5f012608701149fa939e5645 ]

A statement was originally added in 2006 to shut up a gcc warning,
now but now clang warns about it:

fs/jfs/jfs_txnmgr.c:1932:15: error: variable 'pxd' is uninitialized when used within its own initialization
      [-Werror,-Wuninitialized]
                pxd_t pxd = pxd;        /* truncated extent of xad */
                      ~~~   ^~~

Modern versions of gcc are fine without the silly assignment, so just
drop it. Tested with gcc-4.6 (released 2011), 4.7, 4.8, and 4.9.

From: Jon Maloy <jon.maloy@ericsson.com>

[ Upstream commit 737889efe9713a0f20a75fd0de952841d9275e6b ]

When checking the code with clang -Wsometimes-uninitialized we get the
following warning:

if (!tipc_link_is_establishing(l)) {
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
net/tipc/node.c:847:46: note: uninitialized use occurs here
      tipc_bearer_xmit(n->net, bearer_id, &xmitq, maddr);

net/tipc/node.c:831:2: note: remove the 'if' if its condition is always
true
if (!tipc_link_is_establishing(l)) {
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
net/tipc/node.c:821:31: note: initialize the variable 'maddr' to silence
this warning
struct tipc_media_addr *maddr;

We fix this by initializing 'maddr' to NULL. For the matter of clarity,
we also test if 'xmitq' is non-empty before we use it and 'maddr'
further down in the  function. It will never happen that 'xmitq' is non-
empty at the same time as 'maddr' is NULL, so this is a sufficient test.

[ Upstream commit 0ca7ce7db771580433bf24454f7a1542bd326078 ]

This resolves some bugs that affect VIA timer counter accesses.
Avoid lost interrupts caused by reading the counter low byte register.
Make allowance for the fact that the counter will be decremented to
0xFFFF before being reloaded.

[ Upstream commit 7f0d078667a494466991aa7133f49594f32ff6a2 ]

Commit 747834ab8347 ("ARM: OMAP2+: hwmod: revise hardreset behavior") made
the call to _enable() conditional based on no oh->rst_lines_cnt. This
caused the return value to be potentially uninitialized. Curiously we see
no compiler warnings for this, probably as this gets inlined.

We call _setup_reset() from _setup() and only _setup_postsetup() if the
return value is zero. Currently the return value can be uninitialized for
cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.

[ Upstream commit 0e633f97162c1c74c68e2eb20bbd9259dce87cd9 ]

clang warns about a possible variable use that gcc never
complained about:

drivers/media/platform/davinci/isif.c:982:32: error: variable 'frame_size' is uninitialized when used here
      [-Werror,-Wuninitialized]
                dm365_vpss_set_pg_frame_size(frame_size);
                                             ^~~~~~~~~~
drivers/media/platform/davinci/isif.c:887:2: note: variable 'frame_size' is declared here
        struct vpss_pg_frame_size frame_size;
        ^
1 error generated.

There is no initialization for this variable at all, and there
has never been one in the mainline kernel, so we really should
not put that stack data into an mmio register.

On the other hand, I suspect that gcc checks the condition
more closely and notices that the global
isif_cfg.bayer.config_params.test_pat_gen flag is initialized
to zero and never written to from any code path, so anything
depending on it can be eliminated.

To shut up the clang warning, just remove the dead code manually,
it has probably never been used because any attempt to do so
would have resulted in undefined behavior.

Packed bit is not cleared when not using packed mode. This results
in transfer timeouts for the unpacked mode transfers followed by the

[ Upstream commit 1a89ac5b91895127f7c586ec5075c3753ca25501 ]

Fixes: computation of actual bytes to fill/receive in/from FIFO in unpacked
mode when transfer length is not a multiple of requested bits per word.

unpacked mode transfers fails when the transfer includes partial bytes in
the last word.

Total words to be written/read to/from FIFO is computed based on transfer
length and bits per word. Unpacked mode includes 0 padding bytes for partial
words to align with bits per word and these extra bytes are also accounted
for calculating bytes left to transfer in the current driver.

This causes extra bytes access of tx/rx buffers along with buffer index
position crossing actual length where remain_len becomes negative and due to
unsigned type, negative value is a 32 bit representation of signed value
and transferred bytes never meets the actual transfer length resulting in
transfer timeout and a hang.

This patch fixes this with proper computation of the actual bytes to fill in
FIFO during transmit and the actual bytes to read from FIFO during receive
ignoring 0 padded bytes.

From: Martin Sperl <kernel@martin.sperl.org>

[ Upstream commit 509c583620e9053e43d611bf1614fc3d3abafa96 ]

The original driver by default defines num_chipselects as -1.
This actually allicates an array of 65535 entries in
of_spi_register_master.

There is a side-effect for buggy device trees that (contrary to
dt-binding documentation) have no cs-gpio defined.

This mode was never supported by the driver due to limitations
of native cs and additional code complexity and is explicitly
not stated to be implemented.

To keep backwards compatibility with such buggy DTs we limit
the number of chip_selects to 1, as for all practical purposes
it is only ever realistic to use a single chip select in
native cs mode without negative side-effects.

From: Guenter Roeck <linux@roeck-us.net>

[ Upstream commit e95fd518d05bfc087da6fcdea4900a57cfb083bd ]

Super-IO accesses may fail on a system with no or unmapped LPC bus.

Also, other drivers may attempt to access the LPC bus at the same time,
resulting in undefined behavior.

Use request_muxed_region() to ensure that IO access on the requested
address space is supported, and to ensure that access by multiple drivers
is synchronized.

[ Upstream commit 4bcd4ec1017205644a2697bccbc3b5143f522f5f ]

We find that sysctl_tipc_rmem and named_timeout do not have the right minimum
setting. sysctl_tipc_rmem should be larger than zero, like sysctl_tcp_rmem.
And named_timeout as a timeout setting should be not less than zero.

The 32-bit vDSO is not needed and not normally built for 64-bit
little-endian configurations.  However, the vdso_install target still
builds and installs it.  Add the same config condition as is normally
used for the build.

[ Upstream commit c7861adbe37f576931650ad8ef805e0c47564b9a ]

Each eTSEC MAC has its own TBI (SGMII) PCS and private MDIO bus.
But due to a DTS oversight, both SGMII-compatible MACs of the LS1021 SoC
are pointing towards the same internal PCS. Therefore nobody is
controlling the internal PCS of eTSEC0.

Upon initial ndo_open, the SGMII link is ok by virtue of U-boot
initialization. But upon an ifdown/ifup sequence, the code path from
ndo_open -> init_phy -> gfar_configure_serdes does not get executed for
the PCS of eTSEC0 (and is executed twice for MAC eTSEC1). So the SGMII
link remains down for eTSEC0. On the LS1021A-TWR board, to signal this
failure condition, the PHY driver keeps printing
'803x_aneg_done: SGMII link is not ok'.

Also, it changes compatible of mdio0 to "fsl,etsec2-mdio" to match
mdio1 device.

NEXTHDR_MAX is 255.  What happens here is that we take a u8 value
"hdr->nexthdr" from the network and then look it up in
lowpan_nexthdr_nhcs[].  The problem is that if hdr->nexthdr is 0xff then
we read one element beyond the end of the array so the array needs to
be one element larger.

[ Upstream commit 648865a79d8ee3d1aa64aab5eb2a9d12eeed14f9 ]

In 2D transfers (for the AXI DMAC), the number of frames (numf) represents
Y_LENGTH, and the length of a frame is X_LENGTH. 2D transfers are useful
for video transfers where screen resolutions ( X * Y ) are typically
aligned for X, but not for Y.

There is no requirement for Y_LENGTH to be aligned to the bus-width (or
anything), and this is also true for AXI DMAC.

Checking the Y_LENGTH for alignment causes false errors when initiating DMA
transfers. This change fixes this by checking only that the Y_LENGTH is
non-zero.

[ Upstream commit b2cf86e1563e33a14a1c69b3e508d15dc12f804c ]

Packet send checks that msg_name is at least sizeof sockaddr_ll.
Packet recv must return at least this length, so that its output
can be passed unmodified to packet send.

This ceased to be true since adding support for lladdr longer than
sll_addr. Since, the return value uses true address length.

Always return at least sizeof sockaddr_ll, even if address length
is shorter. Zero the padding bytes.

Change v1->v2: do not overwrite zeroed padding again. use copy_len.

[ Upstream commit 6a7c59c6d9f3b280e81d7a04bbe4e55e90152dce ]

A stream may specify a rate range using 'rate_min' and 'rate_max', so a
stream may be valid and not specify any rates. However, as stream cannot
be valid and not have any channel. Let's use this condition instead to
determine if a stream is valid or not.

[ Upstream commit 8f4426aa19fcdb9326ac44154a117b1a3a5ae126 ]

The QP transition optional parameters for the various transition for XRC
QPs are identical to those for RC QPs.

Many of the XRC QP transition optional parameter bits are missing from the
QP optional mask table.  These omissions caused failures when doing XRC QP
state transitions.

For example, when trying to change the response timer of an XRC receive QP
via the RTS2RTS transition, the new timer value was ignored because
MLX5_QP_OPTPAR_RNR_TIMEOUT bit was missing from the optional params mask
for XRC qps for the RTS2RTS transition.

Fix this by adding the missing XRC optional parameters for all QP
transitions to the opt_mask table.

[ Upstream commit 5daab58043ee2bca861068e2595564828f3bc663 ]

The kernel parameter igfx_off is used by users to disable
DMA remapping for the Intel integrated graphic device. It
was designed for bare metal cases where a dedicated IOMMU
is used for graphic. This doesn't apply to virtual IOMMU
case where an include-all IOMMU is used.  This makes the
kernel parameter work with virtual IOMMU as well.

From: Sameer Pujar <spujar@nvidia.com>

[ Upstream commit f33e7bb3eb922618612a90f0a828c790e8880773 ]

Status of ADMA channel registers is not saved and restored during system
suspend. During active playback if system enters suspend, this results in
wrong state of channel registers during system resume and playback fails
to resume properly. Fix this by saving following channel registers in
runtime suspend and restore during runtime resume.
 * ADMA_CH_LOWER_SRC_ADDR
 * ADMA_CH_LOWER_TRG_ADDR
 * ADMA_CH_FIFO_CTRL
 * ADMA_CH_CONFIG
 * ADMA_CH_CTRL
 * ADMA_CH_CMD
 * ADMA_CH_TC
Runtime PM calls will be inovked during system resume path if a playback
or capture needs to be resumed. Hence above changes work fine for system
suspend case.

is unregistered on failure path. Then l2tp_exit_net
is called which will flush NULL workqueue, this patch
add a NULL check to fix it.

From: Dan Carpenter <dan.carpenter@oracle.com>

[ Upstream commit dd6e2a981bfe83aa4a493143fd8cf1edcda6c091 ]

The "b->index" is a u32 the comes from the user in the ioctl.  It hasn't
been checked.  We aren't supposed to use it but we're instead supposed
to use the value that gets written to it when we call videobuf_dqbuf().

The videobuf_dqbuf() first memsets it to zero and then re-initializes it
inside the videobuf_status() function.  It's this final value which we
want.

Hans Verkuil pointed out that we need to check the return from
videobuf_dqbuf().  I ended up doing a little cleanup related to that as
well.

the problem is that "temp_index" can be negative.  This patch changes
the types to unsigned to address this array underflow bug.

The "out_data" variable is uninitialized at the point.  Originally, this
used to print "status" instead and that seems like the correct thing to
print.

If userspace provides a rule blob with trailing data after last target,
we trigger a splat, then convert ruleset to 64bit format (with trailing
data), then pass that to do_replace_finish() which then returns -EINVAL.

Erroring out right away avoids the splat plus unneeded translation and
error unwind.

From: Matthias Kaehlcke <mka@chromium.org>

[ Upstream commit bf45ac18b78038e43af3c1a273cae4ab5704d2ce ]

The CPU load values passed to the thermal_power_cpu_get_power
tracepoint are zero for all CPUs, unless, unless the
thermal_power_cpu_limit tracepoint is enabled too:

  irq/41-rockchip-98    [000] ....   290.972410: thermal_power_cpu_get_power:
  cpus=0000000f freq=1800000 load={{0x0,0x0,0x0,0x0}} dynamic_power=4815

vs

  irq/41-rockchip-96    [000] ....    95.773585: thermal_power_cpu_get_power:
  cpus=0000000f freq=1800000 load={{0x56,0x64,0x64,0x5e}} dynamic_power=4959
  irq/41-rockchip-96    [000] ....    95.773596: thermal_power_cpu_limit:
  cpus=0000000f freq=408000 cdev_state=10 power=416

There seems to be no good reason for omitting the CPU load information
depending on another tracepoint. My guess is that the intention was to
check whether thermal_power_cpu_get_power is (still) enabled, however
'load_cpu != NULL' already indicates that it was at least enabled when
cpufreq_get_requested_power() was entered, there seems little gain
from omitting the assignment if the tracepoint was just disabled, so
just remove the check.

[ Upstream commit b53611fb1ce9b1786bd18205473e0c1d6bfa8934 ]

Commit f33e7bb3eb92 ("dmaengine: tegra210-adma: restore channel status")
added support to save and restore the DMA channel registers when runtime
suspending the ADMA. This change is causing the kernel to crash when
probing the ADMA, if the device is probed deferred when looking up the
channel interrupts. The crash occurs because not all of the channel base
addresses have been setup at this point and in the clean-up path of the
probe, pm_runtime_suspend() is called invoking its callback which
expects all the channel base addresses to be initialised.

Although this could be fixed by simply checking for a NULL address, on
further review of the driver it seems more appropriate that we only call
pm_runtime_get_sync() after all the channel interrupts and base
addresses have been configured. Therefore, fix this crash by moving the
calls to pm_runtime_enable(), pm_runtime_get_sync() and
tegra_adma_init() after the DMA channels have been initialised.

From: Nathan Chancellor <natechancellor@gmail.com>

[ Upstream commit b0576f9ecb5c51e9932531d23c447b2739261841 ]

Clang warns:

drivers/misc/sgi-xp/xpc_partition.c:73:14: warning: variable 'buf' is
uninitialized when used within its own initialization [-Wuninitialized]
        void *buf = buf;
              ~~~   ^~~
1 warning generated.

Arnd's explanation during review:

  /*
   * Returns the physical address of the partition's reserved page through
   * an iterative number of calls.
   *
   * On first call, 'cookie' and 'len' should be set to 0, and 'addr'
   * set to the nasid of the partition whose reserved page's address is
   * being sought.
   * On subsequent calls, pass the values, that were passed back on the
   * previous call.
   *
   * While the return status equals SALRET_MORE_PASSES, keep calling
   * this function after first copying 'len' bytes starting at 'addr'
   * into 'buf'. Once the return status equals SALRET_OK, 'addr' will
   * be the physical address of the partition's reserved page. If the
   * return status equals neither of these, an error as occurred.
   */
  static inline s64
  sn_partition_reserved_page_pa(u64 buf, u64 *cookie, u64 *addr, u64 *len)

  so *len is set to zero on the first call and tells the bios how many
  bytes are accessible at 'buf', and it does get updated by the BIOS to
  tell us how many bytes it needs, and then we allocate that and try again.

[ Upstream commit 72abe3bcf0911d69b46c1e8bdb5612675e0ac42c ]

The locking in force_sig_info is not prepared to deal with a task that
exits or execs (as sighand may change).  The is not a locking problem
in force_sig as force_sig is only built to handle synchronous
exceptions.

Further the function force_sig_info changes the signal state if the
signal is ignored, or blocked or if SIGNAL_UNKILLABLE will prevent the
delivery of the signal.  The signal SIGKILL can not be ignored and can
not be blocked and SIGNAL_UNKILLABLE won't prevent it from being
delivered.

So using force_sig rather than send_sig for SIGKILL is confusing
and pointless.

Because it won't impact the sending of the signal and and because
using force_sig is wrong, replace force_sig with send_sig.

[ Upstream commit ae7352d384a552d8c799c242e74a934809990a71 ]

Both IPv6 and 6lowpan are calling inet_frags_fini() too soon.

inet_frags_fini() is dismantling a kmem_cache, that might be needed
later when unregister_pernet_subsys() eventually has to remove
frags queues from hash tables and free them.

This fixes potential use-after-free, and is a prereq for the following patch.

[ Upstream commit d4ec9550e4b2d2e357a46fdc65d8ef3d4d15984c ]

The assigment of FB_VMODE_NONINTERLACE to var->vmode should be a
bit-wise or of FB_VMODE_NONINTERLACE instead of an assignment,
otherwise the previous clearing of the FB_VMODE_MASK bits of
var->vmode makes no sense and is redundant.

[ Upstream commit d4aa219a074a5abaf95a756b9f0d190b5c03a945 ]

Allow external callers to force the cacheinfo code to release all its
references to cache nodes, e.g. before processing device tree updates
post-migration, and to rebuild the hierarchy afterward.

CPU online/offline must be blocked by callers; enforce this.

pointers, but init returns NULL on error.  Fix this by returning the

From: Jakub Kicinski <jakub.kicinski@netronome.com>

[ Upstream commit 177b8007463c4f36c9a2c7ce7aa9875a4cad9bd5 ]

When GSO frame has to be corrupted netem uses skb_gso_segment()
to produce the list of frames, and re-enqueues the segments one
by one.  The backlog length has to be adjusted to account for
new frames.

The current calculation is incorrect, leading to wrong backlog
lengths in the parent qdisc (both bytes and packets), and
incorrect packet backlog count in netem itself.

Parent backlog goes negative, netem's packet backlog counts
all non-first segments twice (thus remaining non-zero even
after qdisc is emptied).

Move the variables used to count the adjustment into local
scope to make 100% sure they aren't used at any stage in
backports.

Even when running as VM guest (ie pr_iucv != NULL), af_iucv can still
open HiperTransport-based connections. For robust operation these
connections require the af_iucv_netdev_notifier, so register it
unconditionally.

Also handle any error that register_netdevice_notifier() returns.

[ Upstream commit 3572e8aea3bf925dac1dbf86127657c39fe5c254 ]

Besides the alarm, the PCF8563 also has a timer triggered interrupt.
In cases where the previous system left the timer and interrupts on,
or somehow the bits got enabled, the interrupt would keep triggering
as the kernel doesn't know about it.

Clear both the alarm and timer event flags, and disable the interrupts,
before requesting the interrupt line.

From: Rob Clark <robdclark@chromium.org>

[ Upstream commit f47bee2ba447bebc304111c16ef1e1a73a9744dd ]

These regs are write-only, and the hw throws a hissy-fit (ie. reboots)
when we try to read them for GPU state snapshot, in response to a GPU
hang.  It is rather impolite when GPU recovery triggers an insta-
reboot, so lets remove the TPL1 registers from the snapshot.

From: Ravi Bangoria <ravi.bangoria@linux.ibm.com>

[ Upstream commit 913a90bc5a3a06b1f04c337320e9aeee2328dd77 ]

perf_event_open() limits the sample_period to 63 bits. See:

  0819b2e30ccb ("perf: Limit perf_event_attr::sample_period to 63 bits")

Make ioctl() consistent with it.

Also on PowerPC, negative sample_period could cause a recursive
PMIs leading to a hang (reported when running perf-fuzzer).

[ Upstream commit c24a5c735f87d0549060de31367c095e8810b895 ]

The commit

  080edf75d337 ("dmaengine: hsu: set HSU_CH_MTSR to memory width")

has been mistakenly submitted. The further investigations show that
the original code does better job since the memory side transfer size
has never been configured by DMA users.

As per latest revision of documentation: "Channel minimum transfer size
(CHnMTSR)... For IOSF UART, maximum value that can be programmed is 64 and
minimum value that can be programmed is 1."

This reverts commit 080edf75d337d35faa6fc3df99342b10d2848d16.

[ Upstream commit 3ddbe913e55516d3e2165d43d4d5570761769878 ]

Make it safe to call iommu_disable during early init error conditions
before mmio_base is set, but after the struct amd_iommu has been added
to the amd_iommu_list. For example, this happens if firmware fails to
fill in mmio_phys in the ACPI table leading to a NULL pointer
dereference in iommu_feature_disable.

ida instances allocate some internal memory for ->free_bitmap
in addition to the base 'struct ida'. Use ida_destroy() to release
that memory at module_exit().

[ Upstream commit 3427beb6375d04e9627c67343872e79341a684ea ]

With gcc 4.1:

    net/rxrpc/output.c: In function ‘rxrpc_send_data_packet’:
    net/rxrpc/output.c:338: warning: ‘ret’ may be used uninitialized in this function

Indeed, if the first jump to the send_fragmentable label is made, and
the address family is not handled in the switch() statement, ret will be
used uninitialized.

Fix this by BUG()'ing as is done in other places in rxrpc where internal
support for future address families will need adding.  It should not be
possible to reach this normally as the address families are checked
up-front.

[ Upstream commit 9dea44c91469512d346e638694c22c30a5273992 ]

devm_ioremap_resource() does not currently take 'const' arguments,
which results in a warning from the first driver trying to do it
anyway:

From: Xi Wang <wangxi11@huawei.com>

[ Upstream commit ec5bc2cc69b4fc494e04d10fc5226f6f9cf67c56 ]

When smmu is enable, if execute the perftest command and then use 'kill
-9' to exit, follow this operation repeatedly, the kernel will have a high
probability to print the following smmu event:

  arm-smmu-v3 arm-smmu-v3.1.auto: event 0x10 received:
  arm-smmu-v3 arm-smmu-v3.1.auto:  0x00007d0000000010

  arm-smmu-v3 arm-smmu-v3.1.auto:  0x00000000f47cf000

This is because the hw will periodically refresh the qpc cache until the
next reset.

This patch fixed it by removing the action that release qpc memory in the
'hns_roce_qp_free' function.

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 7c116e02a4a7575c8c62bfd2106e3e3ec8fb99dc ]

clang warns about an overly large stack frame in one function
when it decides to inline all __qed_get_vport_*() functions into
__qed_get_vport_stats():

drivers/net/ethernet/qlogic/qed/qed_l2.c:1889:13: error: stack frame size of 1128 bytes in function '_qed_get_vport_stats' [-Werror,-Wframe-larger-than=]

Use a noinline_for_stack annotation to prevent clang from inlining
these, which keeps the maximum stack usage at around half of that
in the worst case, similar to what we get with gcc.

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit bc83f79bd2119230888fb8574639d5a51b38f903 ]

Generally, declaring a platform device as a static variable is
a bad idea and can cause all kinds of problems, in particular
with the DMA configuration and lifetime rules.

A specific problem we hit here is from a bug in clang that warns
about certain (otherwise valid) macros when used in static variables:

drivers/misc/mic/card/mic_x100.c:285:27: warning: shift count >= width of type [-Wshift-count-overflow]
static u64 mic_dma_mask = DMA_BIT_MASK(64);
                          ^~~~~~~~~~~~~~~~
include/linux/dma-mapping.h:141:54: note: expanded from macro 'DMA_BIT_MASK'
 #define DMA_BIT_MASK(n) (((n) == 64) ? ~0ULL : ((1ULL<<(n))-1))
                                                     ^ ~~~

A slightly better way here is to create the platform device dynamically
and set the dma mask in the probe function.
This avoids the warning and some other problems, but is still not ideal
because the device creation should really be separated from the driver,
and the fact that the device has no parent means we have to force
the dma mask rather than having it set up from the bus that the device
is actually on.

APIC_DM_NMI is clearly not a vector number. It's defined to 0x400 which is
outside the vector space.

Use NMI_VECTOR instead as that's what it is intended to be.

[ Upstream commit 315c69261dd3fa12dbc830d4fa00d1fad98d3b03 ]

Save the offsets of the start of each argument to avoid having to update
pointers to each argument after every corename krealloc and to avoid
having to duplicate the memory for the dump command.

Executable names containing spaces were previously being expanded from
%e or %E and then split in the middle of the filename.  This is
incorrect behaviour since an argument list can represent arguments with
spaces.

The splitting could lead to extra arguments being passed to the core
dump handler that it might have interpreted as options or ignored
completely.

Core dump handlers that are not aware of this Linux kernel issue will be
using %e or %E without considering that it may be split and so they will
be vulnerable to processes with spaces in their names breaking their
argument list.  If their internals are otherwise well written, such as
if they are written in shell but quote arguments, they will work better
after this change than before.  If they are not well written, then there
is a slight chance of breakage depending on the details of the code but
they will already be fairly broken by the split filenames.

Core dump handlers that are aware of this Linux kernel issue will be
placing %e or %E as the last item in their core_pattern and then
aggregating all of the remaining arguments into one, separated by
spaces.  Alternatively they will be obtaining the filename via other
methods.  Both of these will be compatible with the new arrangement.

A side effect from this change is that unknown template types (for
example %z) result in an empty argument to the dump handler instead of
the argument being dropped.  This is a desired change as:

It is easier for dump handlers to process empty arguments than dropped
ones, especially if they are written in shell or don't pass each
template item with a preceding command-line option in order to
differentiate between individual template types.  Most core_patterns in
the wild do not use options so they can confuse different template types
(especially numeric ones) if an earlier one gets dropped in old kernels.
If the kernel introduces a new template type and a core_pattern uses it,
the core dump handler might not expect that the argument can be dropped
in old kernels.

For example, this can result in security issues when %d is dropped in
old kernels.  This happened with the corekeeper package in Debian and
resulted in the interface between corekeeper and Linux having to be
rewritten to use command-line options to differentiate between template
types.

The core_pattern for most core dump handlers is written by the handler
author who would generally not insert unknown template types so this
change should be compatible with all the core dump handlers that exist.

Currently when the call to ext4_htree_store_dirent fails the error return
variable 'ret' is is not being set to the error code and variable count is
instead, hence the error code is not being returned.  Fix this by assigning
ret to the error return code.

[ Upstream commit 33da8e7c814f77310250bb54a9db36a44c5de784 ]

My recent to change to only use force_sig for a synchronous events
wound up breaking signal reception cifs and drbd.  I had overlooked
the fact that by default kthreads start out with all signals set to
SIG_IGN.  So a change I thought was safe turned out to have made it
impossible for those kernel thread to catch their signals.

Reverting the work on force_sig is a bad idea because what the code
was doing was very much a misuse of force_sig.  As the way force_sig
ultimately allowed the signal to happen was to change the signal
handler to SIG_DFL.  Which after the first signal will allow userspace
to send signals to these kernel threads.  At least for
wake_ack_receiver in drbd that does not appear actively wrong.

So correct this problem by adding allow_kernel_signal that will allow
signals whose siginfo reports they were sent by the kernel through,
but will not allow userspace generated signals, and update cifs and
drbd to call allow_kernel_signal in an appropriate place so that their
thread can receive this signal.

Fixing things this way ensures that userspace won't be able to send
signals and cause problems, that it is clear which signals the
threads are expecting to receive, and it guarantees that nothing
else in the system will be affected.

This change was partly inspired by similar cifs and drbd patches that
added allow_signal.

[ Upstream commit 12051b318bc3ce5b42d6d786191008284b067d83 ]

The code in question is modifying a variable declared const through
pointer manipulation.  Such code is explicitly undefined behavior, and
is the lone issue preventing malta_defconfig from booting when built
with Clang:

If an attempt is made to modify an object defined with a const-qualified
type through use of an lvalue with non-const-qualified type, the
behavior is undefined.

LLVM is removing such assignments. A simple fix is to not declare
variables const that you plan on modifying.  Limiting the scope would be
a better method of preventing unwanted writes to such a variable.

Further, the code in question mentions "compiler bugs" without any links
to bug reports, so it is difficult to know if the issue is resolved in
GCC. The patch was authored in 2006, which would have been GCC 4.0.3 or
4.1.1. The minimal supported version of GCC in the Linux kernel is
currently 4.6.

For what its worth, there was UB before the commit in question, it just
added a barrier and got lucky IRT codegen. I don't think there's any
actual compiler bugs related, just runtime bugs due to UB.

From: Linus Torvalds <torvalds@linux-foundation.org>

[ Upstream commit ab9bb6318b0967671e0c9b6537c1537d51ca4f45 ]

Commit dfe2a77fd243 ("kfifo: fix kfifo_alloc() and kfifo_init()") made
the kfifo code round the number of elements up.  That was good for
__kfifo_alloc(), but it's actually wrong for __kfifo_init().

The difference? __kfifo_alloc() will allocate the rounded-up number of
elements, but __kfifo_init() uses an allocation done by the caller.  We
can't just say "use more elements than the caller allocated", and have
to round down.

The good news? All the normal cases will be using power-of-two arrays
anyway, and most users of kfifo's don't use kfifo_init() at all, but one
of the helper macros to declare a KFIFO that enforce the proper
power-of-two behavior.  But it looks like at least ibmvscsis might be
affected.

The bad news? Will Deacon refers to an old thread and points points out
that the memory ordering in kfifo's is questionable.  See

  https://lore.kernel.org/lkml/20181211034032.32338-1-yuleixzhang@tencent.com/

for more.

From: Guenter Roeck <linux@roeck-us.net>

[ Upstream commit 7d82fcc9d9e81241778aaa22fda7be753e237d86 ]

Writes into limit registers fail if the temperature written is negative.
The regmap write operation checks the value range, regmap_write accepts
an unsigned int as parameter, and the temperature value passed to
regmap_write is kept in a variable declared as long. Negative values
are converted large unsigned integers, which fails the range check.
Fix by type casting the temperature to u16 when calling regmap_write().

From: Stephen Boyd <swboyd@chromium.org>

[ Upstream commit 8288022284859acbcc3cf1a073a1e2692d6c2543 ]

We may want to use the device pointer in device_init_wakeup() with
functions that expect the device to already be added with device_add().
For example, if we were to link the device initializing wakeup to
something in sysfs such as a class for wakeups we'll run into an error.
It looks like this code was written with the assumption that the device
would be added before initializing wakeup due to the order of operations
in power_supply_unregister().

Let's change the order of operations so we don't run into problems here.

From: Dan Carpenter <dan.carpenter@oracle.com>

[ Upstream commit 329101244f214952606359d254ae883b7109e1a5 ]

The problem is in gb_lights_request_handler().  If we get a request to
change the config then we release the light with gb_lights_light_release()
and re-allocated it.  However, if the allocation fails part way through
then we call gb_lights_light_release() again.  This can lead to a couple
different double frees where we haven't cleared out the original values:

	gb_lights_light_v4l2_unregister(light);
	...
	kfree(light->channels);
	kfree(light->name);

I also made a small change to how we set "light->channels_count = 0;".
The original code handled this part fine and did not cause a use after
free but it was sort of complicated to read.

[ Upstream commit 6e1cdedcf0362fed3aedfe051d46bd7ee2a85fe1 ]

NETDEV_TX_BUSY really should only be used by drivers that call
netif_tx_stop_queue() at the wrong moment. If dma_map_single() is
failed to map tx DMA buffer, it might trigger an infinite loop.
This patch use NETDEV_TX_OK instead of NETDEV_TX_BUSY, and change
printk to pr_err_ratelimited.

[ Upstream commit 7764d56baa844d7f6206394f21a0e8c1f303c476 ]

If we are able to load an existing inode cache off disk, we set the state
of the cache to BTRFS_CACHE_FINISHED, but we don't wake up any one waiting
for the cache to be available. This means that anyone waiting for the
cache to be available, waiting on the condition that either its state is
BTRFS_CACHE_FINISHED or its available free space is greather than zero,
can hang forever.

This could be observed running fstests with MOUNT_OPTIONS="-o inode_cache",
in particular test case generic/161 triggered it very frequently for me,
producing a trace like the following:

  [63795.739712] BTRFS info (device sdc): enabling inode map caching

Fix this by adding a wake_up() call right after setting the cache state to
BTRFS_CACHE_FINISHED, at start_caching(), when we are able to load the
cache from disk.

[ Upstream commit 49f6c90bf6805948b597eabb499e500a47cf24be ]

sonic_send_packet will be processed in irq or non-irq
context, so it would better use dev_kfree_skb_any
instead of dev_kfree_skb.

addrconf_dad_work is kicked to be scheduled when a device is brought
up. There is a race between addrcond_dad_work getting scheduled and
taking the rtnl lock and a process taking the link down (under rtnl).
The latter removes the host route from the inet6_addr as part of
addrconf_ifdown which is run for NETDEV_DOWN. The former attempts
to use the host route in ipv6_ifa_notify. If the down event removes
the host route due to the race to the rtnl, then the BUG listed above
occurs.

This scenario does not occur when the ipv6 address is not kept
(net.ipv6.conf.all.keep_addr_on_down = 0) as addrconf_ifdown sets the
state of the ifp to DEAD. Handle when the addresses are kept by checking
IF_READY which is reset by addrconf_ifdown.

The 'dead' flag for an inet6_addr is set only under rtnl, in
addrconf_ifdown and it means the device is getting removed (or IPv6 is
disabled). The interesting cases for changing the idev flag are
addrconf_notify (NETDEV_UP and NETDEV_CHANGE) and addrconf_ifdown
(reset the flag). The former does not have the idev lock - only rtnl;
the latter has both. Based on that the existing dead + IF_READY check
can be moved to right after the rtnl_lock in addrconf_dad_work.

[ Upstream commit 3a8ecc935efabdad106b5e06d07b150c394b4465 ]

Commit 7fd8930f26be4

  "nvme: add a common helper to read Identify Controller data"

has re-introduced an issue that we have attempted to work around in the
past, in commit a310acd7a7ea ("NVMe: use split lo_hi_{read,write}q").

The problem is that some PCIe NVMe controllers do not implement 64-bit
outbound accesses correctly, which is why the commit above switched
to using lo_hi_[read|write]q for all 64-bit BAR accesses occuring in
the code.

In the mean time, the NVMe subsystem has been refactored, and now calls
into the PCIe support layer for NVMe via a .reg_read64() method, which
fails to use lo_hi_readq(), and thus reintroduces the problem that the
workaround above aimed to address.

Given that, at the moment, .reg_read64() is only used to read the
capability register [which is known to tolerate split reads], let's
switch .reg_read64() to lo_hi_readq() as well.

This fixes a boot issue on some ARM boxes with NVMe behind a Synopsys
DesignWare PCIe host controller.

[ Upstream commit 36453c852816f19947ca482a595dffdd2efa4965 ]

If llc_conn_state_process() sees that llc_conn_service() put the skb on
a list, it will drop one fewer references to it.  This is wrong because
the current behavior is that llc_conn_service() never consumes a
reference to the skb.

The code also makes the number of skb references being dropped
conditional on which of ind_prim and cfm_prim are nonzero, yet neither
of these affects how many references are *acquired*.  So there is extra
code that tries to fix this up by sometimes taking another reference.

Remove the unnecessary/broken refcounting logic and instead just add an
skb_get() before the only two places where an extra reference is
actually consumed.

From: Antonio Borneo <antonio.borneo@st.com>

[ Upstream commit 5da202c88f8c355ad79bc2e8eb582e6d433060e7 ]

The field "name" in struct ptp_clock_info has a fixed size of 16
chars and is used as zero terminated string by clock_name_show()
in drivers/ptp/ptp_sysfs.c
The current initialization value requires 17 chars to fit also the
null termination, and this causes overflow to the next bytes in
the struct when the string is read as null terminated:
	hexdump -C /sys/class/ptp/ptp0/clock_name
	00000000  73 74 6d 6d 61 63 5f 70  74 70 5f 63 6c 6f 63 6b  |stmmac_ptp_clock|
	00000010  a0 ac b9 03 0a                                    |.....|
where the extra 4 bytes (excluding the newline) after the string
represent the integer 0x03b9aca0 = 62500000 assigned to the field
"max_adj" that follows "name" in the same struct.

There is no strict requirement for the "name" content and in the
comment in ptp_clock_kernel.h it's reported it should just be 'A
short "friendly name" to identify the clock'.
Replace it with "stmmac ptp".

[ Upstream commit 78e31c42261779a01bc73472d0f65f15378e9de3 ]

On msm8998, vblank timeouts are observed because the DSI controller is not
reset properly, which ends up stalling the MDP.  This is because the reset
logic is not correct per the hardware documentation.

The documentation states that after asserting reset, software should wait
some time (no indication of how long), or poll the status register until it
returns 0 before deasserting reset.

wmb() is insufficient for this purpose since it just ensures ordering, not
timing between writes.  Since asserting and deasserting reset occurs on the
same register, ordering is already guaranteed by the architecture, making
the wmb extraneous.

Since we would define a timeout for polling the status register to avoid a
possible infinite loop, lets just use a static delay of 20 ms, since 16.666
ms is the time available to process one frame at 60 fps.

[ Upstream commit bd73dfabdda280fc5f05bdec79b6721b4b2f035f ]

Illegal memory will be touch if SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V3
(41) exceed the size of structure sdma_script_start_addrs(40),
thus cause memory corrupt such as slob block header so that kernel
trap into while() loop forever in slob_free(). Please refer to below
code piece in imx-sdma.c:
for (i = 0; i < sdma->script_number; i++)
	if (addr_arr[i] > 0)
		saddr_arr[i] = addr_arr[i]; /* memory corrupt here */
That issue was brought by commit a572460be9cf ("dmaengine: imx-sdma: Add
support for version 3 firmware") because SDMA_SCRIPT_ADDRS_ARRAY_SIZE_V3
(38->41 3 scripts added) not align with script number added in
sdma_script_start_addrs(2 scripts).

[ Upstream commit a7fa12d15855904aff1716e1fc723c03ba38c5cc ]

To corrupt a GSO frame we first perform segmentation.  We then
proceed using the first segment instead of the full GSO skb and
requeue the rest of the segments as separate packets.

If there are any issues with processing the first segment we
still want to process the rest, therefore we jump to the
finish_segs label.

Commit 177b8007463c ("net: netem: fix backlog accounting for
corrupted GSO frames") started using the pointer to the first
segment in the "rest of segments processing", but as mentioned
above the first segment may had already been freed at this point.

Backlog corrections for parent qdiscs have to be adjusted.

If packet corruption failed we jump to finish_segs and return
NET_XMIT_SUCCESS. Seeing success will make the parent qdisc
increment its backlog, that's incorrect - we need to return
NET_XMIT_DROP.

The reset counter is specific for every QCA700x chip. So move this
into the private driver struct. Otherwise we get unpredictable reset
behavior in setups with multiple QCA700x chips.

By default s_maxbytes is set to MAX_NON_LFS, which limits the usable
file size to 2GB, enforced by the vfs.

Commit b9b1f8d5930a ("AFS: write support fixes") added support for the
64-bit fetch and store server operations, but did not change this value.
As a result, attempts to write past the 2G mark result in EFBIG errors:

 $ dd if=/dev/zero of=foo bs=1M count=1 seek=2048
 dd: error writing 'foo': File too large

Set s_maxbytes to MAX_LFS_FILESIZE.

If dma_alloc_coherent() returns NULL in ioat_alloc_ring(), ring
allocation must not proceed.

Until now, if the first call to dma_alloc_coherent() in
ioat_alloc_ring() returned NULL, the processing could proceed, failing
with NULL-pointer dereferencing further down the line.

Since its initial submission, the driver selects V4L2_COLORSPACE_JPEG
for supported formats other than V4L2_MBUS_FMT_SBGGR8_1X8.  According
to v4l2-compliance test program, V4L2_COLORSPACE_JPEG applies
exclusively to V4L2_PIX_FMT_JPEG.  Since the sensor does not support
JPEG format, fix it to always select V4L2_COLORSPACE_SRGB.

[ Upstream commit 1c6a2b63095154bbf9e8f38d79487a728331bf65 ]

User arguments passed to .get/set_fmt() pad operation callbacks may
contain unsupported values.  The driver takes control over frame size
and pixel code as well as colorspace and field attributes but has never
cared for remainig format attributes, i.e., ycbcr_enc, quantization
and xfer_func, introduced by commit 11ff030c7365 ("[media]
v4l2-mediabus: improve colorspace support").  Fix it.

Set up a static v4l2_mbus_framefmt structure with attributes
initialized to reasonable defaults and use it for updating content of
user provided arguments.  In case of V4L2_SUBDEV_FORMAT_ACTIVE,
postpone frame size update, now performed from inside ov6650_s_fmt()
helper, util the user argument is first updated in ov6650_set_fmt() with
default frame format content.  For V4L2_SUBDEV_FORMAT_TRY, don't copy
all attributes to pad config, only those handled by the driver, then
fill the response with the default frame format updated with resulting
pad config format code and frame size.

[ Upstream commit 39034bb0c26b76a2c3abc54aa28c185f18b40c2f ]

Commit da298c6d98d5 ("[media] v4l2: replace video op g_mbus_fmt by pad
op get_fmt") converted a former ov6650_g_fmt() video operation callback
to an ov6650_get_fmt() pad operation callback.  However, the converted
function disregards a format->which flag that pad operations should
obey and always returns active frame format settings.

That can be fixed by always responding to V4L2_SUBDEV_FORMAT_TRY with
-EINVAL, or providing the response from a pad config argument, likely
updated by a former user call to V4L2_SUBDEV_FORMAT_TRY .set_fmt().
Since implementation of the latter is trivial, go for it.

[ Upstream commit fed8d8c7a6dc2a76d7764842853d81c770b0788e ]

The driver does the wrong thing when cs_change is set on a non-last
xfer in a message.  When cs_change is set, the driver deactivates the
CS and leaves it off until a later xfer again has cs_change set whereas
it should be briefly toggling CS off and on again.

This patch brings the behaviour of the driver back in line with the
documentation and common sense.  The delay of 10 us is the same as is
used by the default spi_transfer_one_message() function in spi.c.

When building with Clang + -Wtautological-pointer-compare:

[ Upstream commit e21be0d1d7bd7f78a77613f6bcb6965e72b22fc1 ]

Save and restore top PLL related configuration registers for big (APLL)
and LITTLE (KPLL) cores during suspend/resume cycle. So far, CPU clocks
were reset to default values after suspend/resume cycle and performance
after system resume was affected when performance governor has been selected.

[ Upstream commit b1335f5b0486f61fb66b123b40f8e7a98e49605d ]

This patch fixes an unintended sign extension on left shifts. From Colin
King: "Shifting a u8 left will cause the value to be promoted to an
integer. If the top bit of the u8 is set then the following conversion to
an u64 will sign extend the value causing the upper 32 bits to be set in
the result."

Fix this by using get_unaligned_be*() instead.

[ Upstream commit 458ea3ad033fc86e291712ce50cbe60c3428cf30 ]

Those regulators are not actually supported by the AB8500 regulator
driver. There is no ab8500_regulator_info for them and no entry in
ab8505_regulator_match.

As such, they cannot be registered successfully, and looking them
up in ab8505_regulator_match causes an out-of-bounds array read.

[ Upstream commit a9af3fdcc4258af406879eca63d82e9d6baa892e ]

In build_sit_entries(), if valid_blocks in SIT block is smaller than
valid_blocks in journal, for below calculation:

sbi->discard_blks += old_valid_blocks - se->valid_blocks;

There will be two times potential overflow:
- old_valid_blocks - se->valid_blocks will overflow, and be a very
large number.
- sbi->discard_blks += result will overflow again, comes out a correct
result accidently.

Anyway, it should be fixed.

[ Upstream commit b756ad928d98e5ef0b74af7546a6a31a8dadde00 ]

KCSAN reported the following data-race [1]

Adding a couple of READ_ONCE()/WRITE_ONCE() should silence it.

Since the report hinted about multiple cpus using the history
concurrently, I added a test avoiding writing on it if the
victim slot already contains the desired value.

[ Upstream commit 74887542fdcc92ad06a48c0cca17cdf09fc8aa00 ]

Per Documentation/DMA-API-HOWTO.txt,
To unmap a scatterlist, just call:
	dma_unmap_sg(dev, sglist, nents, direction);

.. note::

	The 'nents' argument to the dma_unmap_sg call must be
	the _same_ one you passed into the dma_map_sg call,
	it should _NOT_ be the 'count' value _returned_ from the
	dma_map_sg call.

However in the driver, priv->nent is directly assigned with value
returned from dma_map_sg, and dma_unmap_sg use priv->nent for unmap,
this breaks the API usage.

So introduce a new entry orig_nent to remember 'nents'.

[ Upstream commit e34494c8df0cd96fc432efae121db3212c46ae48 ]

The driver was reading the wrong register as the 10-hour digit due to
a misplaced ')'. It was in fact reading the 1-second digit register due
to this bug.

Also remove the use of a magic number for the hour mask and use the define
for it which was already present.

From: Oliver O'Halloran <oohall@gmail.com>

[ Upstream commit 9d72dcef891030545f39ad386a30cf91df517fb2 ]

On PowerNV the PCIe topology is (currently) managed by the powernv platform
code in Linux in cooperation with the platform firmware. Linux's native
PCIe port service drivers operate independently of both and this can cause
problems.

The main issue is that the portbus driver will conflict with the platform
specific hotplug driver (pnv_php) over ownership of the MSI used to notify
the host when a hotplug event occurs. The portbus driver claims this MSI on
behalf of the individual port services because the same interrupt is used
for hotplug events, PMEs (on root ports), and link bandwidth change
notifications. The portbus driver will always claim the interrupt even if
the individual port service drivers, such as pciehp, are compiled out.

The second, bigger, problem is that the hotplug port service driver
fundamentally does not work on PowerNV. The platform assumes that all
PCI devices have a corresponding arch-specific handle derived from the DT
node for the device (pci_dn) and without one the platform will not allow
a PCI device to be enabled. This problem is largely due to historical
baggage, but it can't be resolved without significant re-factoring of the
platform PCI support.

We can fix these problems in the interim by setting the
"pcie_ports_disabled" flag during platform initialisation. The flag
indicates the platform owns the PCIe ports which stops the portbus driver
from being registered.

This does have the side effect of disabling all port services drivers
that is: AER, PME, BW notifications, hotplug, and DPC. However, this is
not a huge disadvantage on PowerNV since these services are either unused
or handled through other means.

[ Upstream commit 62d91dd2851e8ae2ca552f1b090a3575a4edf759 ]

The INTERRUPT_CNTL2 register expects a valid DMA address, but is
currently set with a GPU MC address.  This can cause problems on
systems that detect the resulting DMA read from an invalid address
(found on a Power8 guest).

Instead, use the DMA address of the dummy page because it will always
be safe.

[ Upstream commit 39a1a8941b27c37f79508426e27a2ec29829d66c ]

Older versions of the Juno *SoC* TRM [1] recommended that the UART clock
source should be 7.2738 MHz, whereas the *system* TRM [2] stated a more
correct value of 7.3728 MHz. Somehow the wrong value managed to end up in
our DT.

Doing a prime factorisation, a modulo divide by 115200 and trying
to buy a 7.2738 MHz crystal at your favourite electronics dealer suggest
that the old value was actually a typo. The actual UART clock is driven
by a PLL, configured via a parameter in some board.txt file in the
firmware, which reads 7.37 MHz (sic!).

Fix this to correct the baud rate divisor calculation on the Juno board.

Commit 01c9348c7620ec65

  powerpc: Use hardware RNG for arch_get_random_seed_* not arch_get_random_*

updated arch_get_random_[int|long]() to be NOPs, and moved the hardware
RNG backing to arch_get_random_seed_[int|long]() instead. However, it
failed to take into account that arch_get_random_int() was implemented
in terms of arch_get_random_long(), and so we ended up with a version
of the former that is essentially a NOP as well.

Fix this by calling arch_get_random_seed_long() from
arch_get_random_seed_int() instead.

I didn't think the patch that this fixes (72abe3bcf091) was in 4.9 (it was May 2019)?  Did Eric's patch to switch from force_sig to send_sig get backported as well?

The global change from force_sig caused module unloading of cifs.ko to fail (since the cifsd process could not be killed, "rmmod cifs"
now would always fail)
