Hello Linus,

arm64 fixes seem to come in pairs recently, so please pull these two for
-rc6. We've got a fix for removing device-tree blobs when doing a make
clean and another one addressing a missing include, which fixes build
failures in -next for allmodconfig (spotted by Mark's buildbot).

Hopefully, that's us done for 3.19.

Cheers,

Will

I you haven't pulled this yet, please discard the request. I'll revert
the above commit as it causes a regression, reported here:

https://lore.kernel.org/all/Ybn4EfweLqKtyW0+@fixkernel.com/

Will is already on holiday, so I'll retag the branch tomorrow and send a
new pull request.

Thanks and sorry for the trouble.

Hi Linus,

Please pull this pair of arm64 fixes for -rc6. There's a fix for missing
locking around kernel page-table allocation causing a crash with
virtio-mem and a fix for a smatch warning in the kexec code where we
would return 0 on the error path.

With any luck, that's us done for the year.

Hi Linus,

Here are some arm64 fixes for -rc6. The main changes are relating to our
handling of access/dirty bits, where our low-level page-table helpers
could lead to stale young mappings and loss of the dirty bit in some
cases (the latter has not been observed in practice, but could happen
when clearing "soft-dirty" if we enabled that). These were posted as
part of a larger series, but the rest of that is less urgent and needs a
v2 which I'll get to shortly.

In other news, we've now got a set of fixes to resolve the
lockdep/tracing problems that have been plaguing us for a while, but
they're still a bit "fresh" and I plan to send them to you next week
after we've got some more confidence in them (although initial CI
results look good).

Anyway, summary in the tag; please pull.

Cheers,

Will

Hi Linus,

Please pull this batch of arm64 fixes for -rc6. Although the diffstat is
a bit larger than we'd usually have at this stage, a decent amount of it
is the addition of comments describing our syscall tracing behaviour, and
also a sweep across all the modular arm64 PMU drivers to make them rebust
against unloading and unbinding.

Summary is in the tag. Although there are a couple of minor things kicking
around at the moment (CPU errata and module PLTs for very large modules),
I'm not expecting any significant changes now for us in 5.8

Cheers,

Will

Hi Linus,

Please pull these arm64 fixes for -rc6. They're almost exclusively
related to CPU errata in CPUs from Broadcom and Qualcomm where the
workarounds were either not being enabled when they should have been or
enabled when they shouldn't have been. The only "interesting" fix is
ensuring that writeable, shared mappings are initially mapped as clean
since we inadvertently broke the logic back in v4.14 and then noticed
the problem via code inspection the other day.

The only critical issue we have outstanding is a sporadic NULL
dereference in the scheduler, which doesn't appear to be arm64-specific
and PeterZ is tearing his hair out over it at the moment.

Cheers,

Will

Hi Linus,

Please pull these two KVM/arm fixes for -rc6. Unusually, we're routing them
via the arm64 tree as per Paolo's request on the list:

  https://lore.kernel.org/kvm/21ae69a2-2546-29d0-bff6-2ea825e3d968@redhat.com/

We don't actually have any other arm64 fixes pending at the moment (touch
wood), so I've pulled from Marc, written a merge commit, tagged the
result and run it through my build/boot/bisect scripts.

Cheers,

Will

Hi Linus,

Please pull these arm64 fixes for -rc6. It's mainly a couple of email
address updates to MAINTAINERS, but we've also fixed a UAPI build issue
with musl libc and an accidental double-initialisation of our pgd_cache
due to a naming conflict with a weak symbol.

There are a couple of outstanding issues that have been reported, but
it doesn't look like they're new and we're still a long way off from
fully debugging them.

Cheers,

Will

Hi Linus,

Please pull these two arm64 fixes for -rc6. They resolve a kernel NULL
dereference in kexec and bogus kernel page table dumping when userspace
is configured for 52-bit virtual addressing.

Cheers,

Will

Steve has a fix for the break-before-make[0].

I've posted some fixes for contiguous hugepages support in preparation
for enabling memory failure handling[1] but as the changes touch
multiple architectures, it may take some time to merge.

I'll take a look at the GUP code next but no promises on a timeframe yet.

Thanks,
Punit

I think Punit and Steve (CC'd) are working on this, but the issues run
beyond the lack of break-before-make. The core GUP code, for example,
doesn't even support hugeptes. There are also dormant issues with hugeptes
and swap/migration entries, which would hit if somebody flipped
CONFIG_ARCH_ENABLE_HUGEPAGE_MIGRATION. Hell, even the pte_huge macro is
bogus if you're using contiguous ptes (granted, it's seldom used, but if
the above are fixed maybe it will be).

Quick aside: is this being worked on for 4.12? If not, should we ping
Linaro and look to get some focus on this? It's right to disable this,
but also painful to those wanting to work on various NFV use cases.

Jon.

Hi Linus,

Please pull these two arm64 fixes for -rc6. We've got a regression fix for
the signal raised when userspace makes an unsupported unaligned access and a
revert of the contiguous (hugepte) support for hugetlb, which has once again
been found to be broken. One day, maybe, we'll get it right.

Cheers,

Will

Hi Linus,

Here are a few more arm64 fixes for 4.3. Again, nothing too significant,
but worth having nonetheless. The MINSIGSTKSZ update is a bit grotty,
but the value we currently have is wrong (too small), so anybody using
that will have issues already. It has Arnd's ack for the asm-generic
change.

Please pull,

Will
