This reverts the following commits that change CMA design in MM.

Revert "ARM: CMA: avoid double mapping to the CMA area if CONFIG_HIGHMEM=y"
This reverts commit 3d2054ad8c2d5100b68b0c0405f89fd90bf4107b.

Revert "mm/cma: remove ALLOC_CMA"
This reverts commit 1d47a3ec09b5489cd915e8f492aa623cdab5d002.

Revert "mm/cma: manage the memory of the CMA area by using the ZONE_MOVABLE"
This reverts commit bad8c6c0b1144694ecb0bc5629ede9b8b578b86e.

Ville reported a following error on i386.

Reason for this error is that the span of MOVABLE_ZONE is extended to
whole node span for future CMA initialization, and, normal memory is
wrongly freed here. I submitted the fix and it seems to work, but,
the other problem happened. It's so late time to fix the later problem
so I decide to reverting the series.

Yes. Reverting seems to be a right decision at this moment.
Could you apply original revert patch from Ville?

Thanks.

It's getting rather late and we don't seem to have a final set of fixes
yet.  Perhaps the best approach here is to revert and try again for
4.18?

Okay. I find the reason about this error.

page_address() is called in dma_direct_alloc() and it returns 'NULL'
since PageHighMem() for CMA memory returns 'true' after my patches
that manages CMA memory by using the ZONE_MOVABLE.

page_address()
{
        if (!PageHighMem())
                return lowmem_address()
        try to find kmap mapping
        if failed, return NULL
}

I assumed that the caller, who want to get the virtual address of the
page, calls the PageHighMem() and creates a new mapping if
PageHighMem() is 'true', but, it looks not true in this case. It knows
where the memory comes from so it directly call the page_address().
This usecase is valid so I should fix the issue on my side.

I have an idea to fix this case but I think that reverting the patches
is the best at this moment since there is not enough time to test a
new idea before the release.

My idea is to change the implementation of the PageHighMem() like as
below.

-#define PageHighMem(__p) is_highmem_idx(page_zonenum(__p))
+#define PageHighMem(__p) (page_to_pfn(__p) >= max_low_pfn)

And then, I will rename PageHighMem() to !PageDirectMapped().

Current PageHighMem() is mostly used to check if the direct mapping
exists or not. Until now, pages on the higher zones (ZONE_HIGHMEM,
ZONE_MOVABLE when ZONE_HIGHMEM is used) are not direct mapped so
previous implementation that checks higher zone implys the existence
of the direct mapping. However, with my patches, it's not true anymore
so implementation need to be changed.

With above idea that checks pfn rather than the zone type, existence
of the mapping can be determined correctly, regardless of the zone
where the pages are belong to. And, page_address() will work
correctly.

If someone has other opinion, please let me know.

Thanks.

This gets me past the initial hurdles. But when I tried it on a machine
with an actual 32 bit OS it oopsed again later in the boot.

Good point! Reason of the crash is that the span of MOVABLE_ZONE is
extended to whole node span for future CMA initialization, and,
normal memory is wrongly freed here.

Here goes the fix. Ville, Could you test below patch?
I re-generated the issue on my side and this patch fixed it.

Thanks.

Subject: [PATCH] x86/32/highmem: check if the zone is matched when free
 highmem pages on init

If CONFIG_CMA is enabled, it extends the span of the MOVABLE_ZONE
to manage the CMA memory later. And, in this case, the span of the
MOVABLE_ZONE could overlap the other zone's memory. We need to
avoid freeing this overlapped memory here since it would be the
memory of the other zone. Therefore, this patch adds a check
whether the page is indeed on the requested zone or not. Skipped
page will be freed when the memory of the matched zone is freed.

With DEBUG_VM the machine doesn't get far enough to print anything on
the serial console.

DEBUG_HIGHMEM didn't give me any new output.

For a point of reference, arm with this configuration doesn't hit this bug
because highmem pages are freed via the memblock interface only instead
of iterating through each zone. It looks like the x86 highmem code
assumes only a single highmem zone and/or it's disjoint?

It has CONFIG_HAVE_MEMBLOCK_NODE_MAP so the movable_zone initialization
depends on quite some crazy movable init code paths. So maybe that is
the place to look at.

This smells like a fallout. Reserved pages clearly underflowed which
suggested we are initializating more than we should.

Attached. Not sure there's anything particularly useful in it though
since I've now seen this on all the highmem systems I've booted.


BTW I just noticed that the reported memory sizes look pretty crazy:

Memory: 3926480K/3987424K available (5254K kernel code, 561K rwdata,
2156K rodata, 572K init, 9308K bss, 56848K reserved,
4096K cma-reserved, 3078532K highmem)

vs.

Memory: 7001976K/3987424K available (5254K kernel code, 561K rwdata,
2156K rodata, 572K init, 9308K bss, 4291097664K reserved,
4096K cma-reserved, 7005012K highmem)

I'll see about grabbing another log.

Looking closer, I _think_ that the bug is in set_highmem_pages_init->is_highmem
and zone_movable_is_highmem might force CMA pages in the zone movable to
be initialized as highmem. And that sounds supicious to me. Joonsoo?

Could you provide your .config please?

OK, so this looks the be the source of the problem. -128 would be a
buddy page but I do not see anything that would set the counter to -127
and the real map count updates shouldn't really happen that early.

Maybe CONFIG_DEBUG_VM and CONFIG_DEBUG_HIGHMEM will tell us more.

/proc/zoneinfo with the patch reverted, etc., the usual stuff when
reporting a bug? Thanks.

The machine I have in front of me right now didn't give me anything.
Black screen, and netconsole was silent. No serial port on this
machine unfortunately.

Is there any bug report with some more details? It is much more
preferable to fix the issue rather than to revert the whole thing
right away.

Um, any more details? This looks rather rash IMHO. Or was there some
previous discussion I haven't seen? We are at rc5 so it can still be
fixed rather than reverted?

This reverts commit bad8c6c0b1144694ecb0bc5629ede9b8b578b86e.

Make x86 with HIGHMEM=y and CMA=y boot again.
