After commit f227f0faf63b ("slub: fix unreclaimable slab stat for bulk
free"), the check for free nonslab page is replaced by VM_BUG_ON_PAGE,
which only check with CONFIG_DEBUG_VM enabled, but this config may
impact performance, so it only for debug.
Commit 0937502af7c9 ("slub: Add check for kfree() of non slab objects.")
add the ability, which should be needed in any configs to catch the
invalid free, they even could be potential issue, eg, memory corruption,
use after free and double free, so replace VM_BUG_ON_PAGE to
WARN_ON_ONCE, add object address printing to help use to debug the
issue.

The fallthrough comment for an ignored cmpxchg() return value produces a
harmless warning with 'make W=1':
fs/posix_acl.c: In function 'get_acl':
fs/posix_acl.c:127:36: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]
127 | /* fall through */ ;
| ^
Simplify it as a step towards a clean W=1 build. As all architectures
define cmpxchg() as a statement expression these days, it is no longer
necessary to evaluate its return code, and the if() can just be droped.

ocfs2_zero_range_for_truncate() can try to zero pages beyond current
inode size despite the fact that underlying blocks should be already
zeroed out and writeback will skip writing such pages anyway. Avoid the
pointless work.

Patch series "ocfs2: Truncate data corruption fix".
As further testing has shown, commit 5314454ea3f ("ocfs2: fix data
corruption after conversion from inline format") didn't fix all the data
corruption issues the customer started observing after 6dbf7bb55598
("fs: Don't invalidate page buffers in block_write_full_page()") This
time I have tracked them down to two bugs in ocfs2 truncation code.
One bug (truncating page cache before clearing tail cluster and setting
i_size) could cause data corruption even before 6dbf7bb55598, but before
that commit it needed a race with page fault, after 6dbf7bb55598 it
started to be pretty deterministic.
Another bug (zeroing pages beyond old i_size) used to be harmless
inefficiency before commit 6dbf7bb55598. But after commit 6dbf7bb55598
in combination with the first bug it resulted in deterministic data
corruption.
Although fixing only the first problem is needed to stop data
corruption, I've fixed both issues to make the code more robust.
This patch (of 2):
ocfs2_truncate_file() did unmap invalidate page cache pages before
zeroing partial tail cluster and setting i_size. Thus some pages could
be left (and likely have left if the cluster zeroing happened) in the
page cache beyond i_size after truncate finished letting user possibly
see stale data once the file was extended again. Also the tail cluster
zeroing was not guaranteed to finish before truncate finished causing
possible stale data exposure. The problem started to be particularly
easy to hit after commit 6dbf7bb55598 "fs: Don't invalidate page buffers
in block_write_full_page()" stopped invalidation of pages beyond i_size
from page writeback path.
Fix these problems by unmapping and invalidating pages in the page cache
after the i_size is reduced and tail cluster is zeroed out.

The reference counting issue happens in two exception handling paths of
ocfs2_replay_truncate_records(). When executing these two exception
handling paths, the function forgets to decrease the refcount of handle
increased by ocfs2_start_trans(), causing a refcount leak.
Fix this issue by using ocfs2_commit_trans() to decrease the refcount of
handle in two handling paths.

If both "mistake" version and "correction" version are the same, a
warning message is created by checkpatch which is impossible to fix.
But it was noticed that Colan Ian King created a commit e6c0a0889b80
("ALSA: aloop: Fix spelling mistake "synchronization" ->
"synchronization"") which suggests that this spelling mistake was fixed
by replacing the word "synchronization" with itself. But the actual
diff shows that the mistake in the code was "sychronization". It is
rather likely that the "mistake" in spelling.txt should have been the
latter.

elf_validity_check() checks ELF headers for errors and ELF Spec.
compliance and if any of them fail it returns -ENOEXEC from all of
these error paths. Almost all of them don't print any messages.
When elf_validity_check() returns an error, load_module() prints an
error message without error code. It is hard to determine why the
module ELF structure is invalid, even if load_module() prints the
error code which is -ENOEXEC in all of these cases.
Change to print useful error messages from elf_validity_check() to
clearly say what went wrong and why the ELF validity checks failed.
Remove the load_module() error message which is no longer needed.
This patch includes changes to fix build warns on 32-bit platforms:

validate_section_offset() uses unsigned long local variable to
add/store shdr->sh_offset and shdr->sh_size on all platforms.
unsigned long is too short when sh_offset is Elf64_Off which
would be the case on 64bit ELF headers.
Without this fix applied we were shorting the design of modules
to have section headers placed within the 32-bit boundary (4 GiB)
instead of 64-bits when on 64-bit architectures (which allows for
up to 16,777,216 TiB). In practice this just meant we were limiting
modules sections to below 4 GiB even on 64-bit systems. This then
should not really affect any real-world use case as modules these
days obviously should likely never exceed 1 GiB in size overall.
A specially crafted invalid module might succeed to skip validation
in validate_section_offset() due to this mistake, but in such case
no impact is observed through code inspection given the correct data
types are used for the copy of the module when needed on move_module()
when the section type is not SHT_NOBITS (which indicates no the
section occupies no space on the file).
Fix the overflow problem using the right size local variable when
CONFIG_64BIT is defined.

Pull SCSI updates from James Bottomley:
"This consists of the usual driver updates (ufs, smartpqi, lpfc,
target, megaraid_sas, hisi_sas, qla2xxx) and minor updates and bug
fixes.
Notable core changes are the removal of scsi->tag which caused some
churn in obsolete drivers and a sweep through all drivers to call
scsi_done() directly instead of scsi->done() which removes a pointer
indirection from the hot path and a move to register core sysfs files
earlier, which means they're available to KOBJ_ADD processing, which
necessitates switching all drivers to using attribute groups"

Pull pin control updates from Linus Walleij:
"The most interesting aspect is that we now have initial support for
the Apple pin controller as used in the M1 laptops and the iPhones
which is a step forward for using Linux efficiently on this Apple
silicon.
Core changes:
- Add infrastructure for per-parent interrupt data to support the
Apple pin controller.
New drivers:
- New combined pin control and GPIO driver for the Apple SoC. This is
used in all modern Apple silicon such as the M1 laptops but also in
at least recent iPhone variants.
- New subdriver for the Qualcomm SM6350
- New subdriver for the Qualcomm QCM2290
- New subdriver for the Qualcomm PM6350
- New subdriver for the Uniphier NX1
- New subdriver for the Samsung ExynosAutoV9
- New subdriver for the Mediatek MT7986
- New subdriver for the nVidia Tegra194
Improvements:
- Improve power management in the Mediatek driver.
- Improvements to the Renesas internal consistency checker.
- Convert the Rockchip pin control device tree bindings to YAML.
- Finally convert the Qualcomm PMIC SSBI and SPMI MPP GPIO driver to
use hierarchical interrupts.
