In some cases it appears the invalidation of a hwpoisoned page fails
because the page is still mapped in another process. This can cause a
program to be continuously restarted and die when it page faults on the
page that was not invalidated. Avoid that problem by unmapping the
hwpoisoned page when we find it.
Another issue is that sometimes we end up oopsing in finish_fault, if
the code tries to do something with the now-NULL vmf->page. I did not
hit this error when submitting the previous patch because there are
several opportunities for alloc_set_pte to bail out before accessing
vmf->page, and that apparently happened on those systems, and most of
the time on other systems, too.
However, across several million systems that error does occur a handful
of times a day. It can be avoided by returning VM_FAULT_NOPAGE which
will cause do_read_fault to return before calling finish_fault.

If the kfence object is allocated to be used for objects vector, then
this slot of the pool eventually being occupied permanently since the
vector is never freed. The solutions could be (1) freeing vector when
the kfence object is freed or (2) allocating all vectors statically.
Since the memory consumption of object vectors is low, it is better to
chose (2) to fix the issue and it is also can reduce overhead of vectors
allocating in the future.

The access to mlock_pvec is protected by disabling preemption via
get_cpu_var() or implicit by having preemption disabled by the caller
(in mlock_page_drain() case). This breaks on PREEMPT_RT since
folio_lruvec_lock_irq() acquires a sleeping lock in this section.
Create struct mlock_pvec which consits of the local_lock_t and the
pagevec. Acquire the local_lock() before accessing the per-CPU pagevec.
Replace mlock_page_drain() with a _local() version which is invoked on
the local CPU and acquires the local_lock_t and a _remote() version
which uses the pagevec from a remote CPU which offline.

Update Documentation/vm/unevictable-lru.rst to reflect the changes made
by the mm/munlock series: keeping an mlock_count instead of page_mlock()
(formerly try_to_munlock()) and munlock_vma_pages_all() etc. Also make
other little updates or cleanups wherever noticed.
But, I apologize, this is already out of date, in that "folio" appears
nowhere: 5.18 will be in a transitional state from "page" to "folio",
and documenting its current mix of the two does not help to understand
"the Unevictable LRU". Should be revisited when naming is more settled.

Mike reports that LTP memcg_stat_test usually leads to
memcg_stat_test 3 TINFO: Test unevictable with MAP_LOCKED
memcg_stat_test 3 TINFO: Running memcg_process --mmap-lock1 -s 135168
memcg_stat_test 3 TINFO: Warming up pid: 3460
memcg_stat_test 3 TINFO: Process is still here after warm up: 3460
memcg_stat_test 3 TFAIL: unevictable is 122880, 135168 expected
but may also lead to

memcg_stat_test 4 TINFO: Warming up pid: 4271
memcg_stat_test 4 TINFO: Process is still here after warm up: 4271
memcg_stat_test 4 TFAIL: unevictable is 122880, 135168 expected
or both. A wee bit flaky.
follow_page_pte() used to have an lru_add_drain() per each page mlocked,
and the test came to rely on accurate stats. The pagevec to be drained
is different now, but still covered by lru_add_drain(); and, never mind
the test, I believe it's in everyone's interest that a bulk faulting
interface like populate_vma_page_range() or faultin_vma_page_range()
should drain its local pagevecs at the end, to save others sometimes
needing the much more expensive lru_add_drain_all().
This does not absolutely guarantee exact stats - the mlocking task can
be migrated between CPUs as it proceeds - but it's good enough and the
tests pass.

Patch series "nilfs2 lockdep warning fixes".
The first two are to resolve the lockdep warning issue, and the last one
is the accompanying cleanup and low priority.
Based on your comment, this series solves the issue by separating inode
object as needed. Since I was worried about the impact of the object
composition changes, I tested the series carefully not to cause
regressions especially for delicate functions such like disk space
reclamation and snapshots.
This patch (of 3):
If CONFIG_LOCKDEP is enabled, nilfs2 hits lockdep warnings at
inode_to_wb() during page/folio operations for btree nodes:

This is because nilfs2 uses two page caches for each inode and
inode->i_mapping never points to one of them, the btree node cache.
This causes inode_to_wb(inode) to refer to a different page cache than
the caller page/folio operations such like __folio_start_writeback(),
__folio_end_writeback(), or __folio_mark_dirty() acquired the lock.
This patch resolves the issue by allocating and using an additional
inode to hold the page cache of btree nodes. The inode is attached
one-to-one to the traditional nilfs2 inode if it requires a block
mapping with b-tree. This setup change is in memory only and does not
affect the disk format.

This reverts commit 08095d6310a7 ("mm: madvise: skip unmapped vma holes
passed to process_madvise") as process_madvise() fails to return the
exact processed bytes in other cases too.
As an example: if process_madvise() hits mlocked pages after processing
some initial bytes passed in [start, end), it just returns EINVAL
although some bytes are processed. Thus making an exception only for
ENOMEM is partially fixing the problem of returning the proper advised
bytes.
Thus revert this patch and return proper bytes advised.

Expanded testing of DM's bio polling support (using more fio threads
to dm-linear ontop of null_blk) exposed the possibility for polled
bios to hang (repeatedly polling in io_uring) when null_blk responds
with BLK_STS_AGAIN (due to lack of resources):
1) io_complete_rw_iopoll() is called from blkdev_bio_end_io_async() to
notify kiocb is done, that is the completion interface between block
layer and io_uring
2) io_complete_rw_iopoll() is called from io_do_iopoll()
3) dm returns BLK_STS_AGAIN for one bio (on behalf of underlying
driver), then io_complete_rw_iopoll is called, but io_do_iopoll()
doesn't handle -EAGAIN at all (due to logic in io_rw_should_reissue)
4) reason for dm's BLK_STS_AGAIN is underlying null_blk driver ran out
of requests (easier to reproduce by setting low hw_queue_depth).
5) dm should handle BLK_STS_AGAIN for POLLED underlying IO, and may
retry in dm layer.
This fix adds REQ_POLLED specific BLK_STS_AGAIN handling to
dm_io_complete() that clears REQ_POLLED and requeues the bio to DM
using queue_io().

Early alpha processors cannot write a single byte or short; they read 8
bytes, modify the value in registers and write back 8 bytes.
This could cause race condition in the structure dm_io - if the fields
flags and io_count are modified simultaneously.
Fix this bug by using 32-bit flags if we are on Alpha and if we are
compiling for a processor that doesn't have the byte-word-extension.

This reverts commit 6580c5c18fb3df2b11c5e0452372f815deeff895.
This patch is buggy, as noted in the patch linked below. The root cause
has been solved by removing '-mno-global-merge' for the entire kernel.

This flag is specific to clang, where it is only used by the 32-bit and
64-bit ARM backends. In certain situations, the presence of this flag
will cause a warning, as shown by commit 6580c5c18fb3 ("um: clang: Strip
out -mno-global-merge from USER_CFLAGS").
Since commit 61163efae020 ("kbuild: LLVMLinux: Add Kbuild support for
building kernel with Clang") that added this flag back in 2014, there
have been quite a few changes to the GlobalMerge pass in LLVM. Building
several different ARCH=arm and ARCH=arm64 configurations with LLVM 11
(minimum) and 15 (current main version) with this flag removed (i.e.,
with the default of '-mglobal-merge') reveals no modpost warnings, so it
is likely that the issue noted in the comment is no longer relevant due
to changes in LLVM or modpost, meaning this flag can be removed.
If any new warnings show up that are a result of the removal of this
flag, it can be added back under arch/arm{,64}/Makefile to avoid
warnings on other architectures.

pgprot_decrypted is used by AMD SME systems to allow access to memory
that was set to not encrypted using set_memory_decrypted. That only
happens for dma-direct memory as the IOMMU solves the addressing
challenges for the encryption bit using its own remapping.
Move the pgprot_decrypted call out of dma_pgprot which is also used
by the IOMMU mappings and into dma-direct so that it is only used with
memory that was set decrypted.

This reverts commit 37ef4c19b4c659926ce65a7ac709ceaefb211c40.
The touchpad present in the Dell Precision 7550 and 7750 laptops
reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However,
the device is not a clickpad, it is a touchpad with physical buttons.
In order to fix this issue, a quirk for the device was introduced in
libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property:
[Precision 7x50 Touchpad]
MatchBus=i2c
MatchUdevType=touchpad
MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50*
AttrInputPropDisable=INPUT_PROP_BUTTONPAD
However, because of the change introduced in 37ef4c19b4 ("Input: clear
BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped
anymore breaking the device right click button and making impossible to
workaround it in user space.
In order to avoid breakage on other present or future devices, revert
the patch causing the issue.

Before this commit, VolumeDirty will be cleared first in
writeback if 'dirsync' or 'sync' is not enabled. If the power
is suddenly cut off after cleaning VolumeDirty but other
updates are not written, the exFAT filesystem will not be able
to detect the power failure in the next mount.
And VolumeDirty will be set again but not cleared when updating
the parent directory. It means that BootSector will be written at
least once in each write-back, which will shorten the life of the
device.

The Linux kernel exfat driver currently unconditionally strips
trailing periods '.' from path components. This isdone intentionally,
loosely following Windows behaviour and specifications
which state:
#exFAT
The concatenated file name has the same set of illegal characters as
other FAT-based file systems (see Table 31).
#FAT
...
Leading and trailing spaces in a long name are ignored.
Leading and embedded periods are allowed in a name and are stored in
the long name. Trailing periods are ignored.
Note: Leading and trailing space ' ' characters are currently retained
by Linux kernel exfat, in conflict with the above specification.
On Windows 10, trailing and leading space ' ' characters are stripped
from the filenames.
Some implementations, such as fuse-exfat, don't perform path trailer
removal. When mounting images which contain trailing-dot paths, these
paths are unreachable, e.g.:
+ mount.exfat-fuse /dev/zram0 /mnt/test/
FUSE exfat 1.3.0
+ cd /mnt/test/
+ touch fuse_created_dots... ' fuse_created_spaces '

This commit adds "keep_last_dots" mount option that controls whether or
not trailing periods '.' are stripped
from path components during file lookup or file creation.
This mount option can be used to access
paths with trailing periods and disallow creating files with names with
trailing periods. E.g. continuing from the previous example:
+ mount -t exfat -o keep_last_dots /dev/zram0 /mnt/test
+ cd /mnt/test

Debugfs console_log uses devm memory (e.g. debug_info in
cros_ec_console_log_poll()). However, lifecycles of device and debugfs
are independent. An use-after-free issue is observed if userland
program operates the debugfs after the memory has been freed.
The call trace:
do_raw_spin_lock
_raw_spin_lock_irqsave
remove_wait_queue
ep_unregister_pollwait
ep_remove
do_epoll_ctl
A Python example to reproduce the issue:
... import select
... p = select.epoll()
... f = open('/sys/kernel/debug/cros_scp/console_log')
... p.register(f, select.POLLIN)
... p.poll(1)
[(4, 1)] # 4=fd, 1=select.POLLIN
[ shutdown cros_scp at the point ]
... p.poll(1)
[(4, 16)] # 4=fd, 16=select.POLLHUP
... p.unregister(f)
An use-after-free issue raises here. It called epoll_ctl with
EPOLL_CTL_DEL which in turn to use the workqueue in the devm (i.e.
log_wq).
Detaches log reader's workqueue from devm to make sure it is persistent
even if the device has been removed.

cros_ec_trace.h defined 5 tracing events, 2 for cros_ec_proto and
3 for cros_ec_sensorhub_ring.
These 2 files are in different kernel modules, the traces are defined
twice in the kernel which leads to problem enabling only some traces.
Move sensorhub traces from cros_ec_trace.h to cros_ec_sensorhub_trace.h
and enable them only in cros_ec_sensorhub kernel module.
Check we can now enable any single traces: without this patch,
we can only enable all sensorhub traces or none.
