The ACPI_FADT_LOW_POWER_S0 flag merely means that it is better to
use low-power S0 idle on the given platform than S3 (provided that
the latter is supported) and it doesn't preclude using either of
them (which of them will be used depends on the choices made by user
space).
For this reason, there is no benefit from checking that flag in
use_acpi_alarm_quirks().
First off, it cannot be a bug to do S3 with use_acpi_alarm set,
because S3 can be used on systems with ACPI_FADT_LOW_POWER_S0 and it
must work if really supported, so the ACPI_FADT_LOW_POWER_S0 check is
not needed to protect the S3-capable systems from failing.
Second, suspend-to-idle can be carried out on a system with
ACPI_FADT_LOW_POWER_S0 unset and it is expected to work, so if setting
use_acpi_alarm is needed to handle that case correctly, it should be
set regardless of the ACPI_FADT_LOW_POWER_S0 value.
Accordingly, drop the ACPI_FADT_LOW_POWER_S0 check from
use_acpi_alarm_quirks().

Pull tty / serial driver updates from Greg KH:
"Here is the big set of tty and serial driver changes for 6.0-rc1.
It was delayed from last week as I wanted to make sure the last commit
here got some good testing in linux-next and elsewhere as it seemed to
show up only late in testing for some reason.
Nothing major here, just lots of cleanups from Jiri and Ilpo to make
the tty core cleaner (Jiri) and the rs485 code simpler to use (Ilpo).
Also included in here is the obligatory n_gsm updates from Daniel
Starke and lots of tiny driver updates and minor fixes and tweaks for

git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim:
"In this cycle, we mainly fixed some corner cases that manipulate a
per-file compression flag inappropriately. And, we found f2fs counted
valid blocks in a section incorrectly when zone capacity is set, and
thus, fixed it with additional sysfs entry to check it easily.
Lastly, this series includes several patches with respect to the new
atomic write support such as a couple of bug fixes and re-adding
atomic_write_abort support that we removed by mistake in the previous
release.
Enhancements:
- add sysfs entries to understand atomic write operations and zone
capacity
- introduce memory mode to get a hint for low-memory devices
- adjust the waiting time of foreground GC
- decompress clusters under softirq to avoid non-deterministic
latency
- do not skip updating inode when retrying to flush node page
- enforce single zone capacity
Bug fixes:
- set the compression/no-compression flags correctly
- revive F2FS_IOC_ABORT_VOLATILE_WRITE
- check inline_data during compressed inode conversion
- understand zone capacity when calculating valid block count
As usual, the series includes several minor clean-ups and sanity
checks"

If something manages to set the maximum file size to MAX_OFFSET+1, this
can cause the xfs and ext4 filesystems at least to become corrupt.
Ordinarily, the kernel protects against userspace trying this by
checking the value early in the truncate() and ftruncate() system calls
calls - but there are at least two places that this check is bypassed:
(1) Cachefiles will round up the EOF of the backing file to DIO block
size so as to allow DIO on the final block - but this might push
the offset negative. It then calls notify_change(), but this
inadvertently bypasses the checking. This can be triggered if
someone puts an 8EiB-1 file on a server for someone else to try and
access by, say, nfs.
(2) ksmbd doesn't check the value it is given in set_end_of_file_info()
and then calls vfs_truncate() directly - which also bypasses the
check.
In both cases, it is potentially possible for a network filesystem to
cause a disk filesystem to be corrupted: cachefiles in the client's
cache filesystem; ksmbd in the server's filesystem.
nfsd is okay as it checks the value, but we can then remove this check
too.
Fix this by adding a check to inode_newsize_ok(), as called from
setattr_prepare(), thereby catching the issue as filesystems set up to
perform the truncate with minimal opportunity for bypassing the new
check.

Fixes: f44158485826 ("cifsd: add file operations")

AMD's "Technical Guidance for Mitigating Branch Type Confusion,
Rev. 1.0 2022-07-12" whitepaper, under section 6.1.2 "IBPB On
Privileged Mode Entry / SMT Safety" says:
Similar to the Jmp2Ret mitigation, if the code on the sibling thread
cannot be trusted, software should set STIBP to 1 or disable SMT to
ensure SMT safety when using this mitigation.
So, like already being done for retbleed=unret, and now also for
retbleed=ibpb, force STIBP on machines that have it, and report its SMT
vulnerability status accordingly.

When we call xdp_convert_buff_to_frame() to get xdpf, if it returns
NULL, we should check if xdp_page was allocated by xdp_linearize_page().
If it is newly allocated, it should be freed here alone. Just like any
other "goto err_xdp".

Driver's SME is allowed to fill either BSSID or BSS pointers in struct
cfg80211_connect_resp_params when indicating connect response but a
check in __cfg80211_connect_result() is giving unnecessary warning when
driver's SME fills only BSSID pointer and not BSS pointer in struct
cfg80211_connect_resp_params.
In case of mac80211 with auth/assoc path, it is always expected to fill
BSS pointers in struct cfg80211_connect_resp_params when calling
__cfg80211_connect_result() since cfg80211 must have hold BSS pointers
in cfg80211_mlme_assoc().
So, skip the check for the drivers which support cfg80211 connect
callback, for example with brcmfmac is one such driver which had the
warning:
WARNING: CPU: 5 PID: 514 at net/wireless/sme.c:786 __cfg80211_connect_result+0x2fc/0x5c0 [cfg80211]

This reverts commit 4bf7fda4dce22214c70c49960b1b6438e6260b67.
It turns out that it was hopelessly naive to think that this would work,
considering that we've always done this. The first machine I actually
tested this on broke at bootup, getting to
Reached target cryptsetup.target - Local Encrypted Volumes.
and then hanging. It's unclear what actually fails, since there's a lot
else going on around that time (eg amdgpu probing also happens around
that same time, but it could be some other random init thing that didn't
complete earlier and just caused the boot to hang at that point).
The expectations that we should default to some unsafe and untested mode
seems entirely unfounded, and the belief that this wouldn't affect
modern systems is clearly entirely false. The machine in question is
about two years old, so it's not exactly shiny, but it's also not some
dusty old museum piece PDP-11 in a closet.

git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull more device mapper updates from Mike Snitzer:
- Add flags argument to dm_bufio_client_create and introduce
DM_BUFIO_CLIENT_NO_SLEEP flag to have dm-bufio use spinlock rather
than mutex for its locking.
- Add optional "try_verify_in_tasklet" feature to DM verity target.
This feature gives users the option to improve IO latency by using a
tasklet to verify, using hashes in bufio's cache, rather than wait to
schedule a work item via workqueue. But if there is a bufio cache
miss, or an error, then the tasklet will fallback to using workqueue.
- Incremental changes to both dm-bufio and the DM verity target to use
jump_label to minimize cost of branching associated with the niche
"try_verify_in_tasklet" feature. DM-bufio in particular is used by
quite a few other DM targets so it doesn't make sense to incur
additional bufio cost in those targets purely for the benefit of this
niche verity feature if the feature isn't ever used.
- Optimize verity_verify_io, which is used by both workqueue and
tasklet based verification, if FEC is not configured or tasklet based
verification isn't used.
- Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE
flag since it uses WQ_UNBOUND. Also, use the WQ_HIGHPRI flag if
"try_verify_in_tasklet" is specified.
