15d9fcbb3e arm64: dts: qcom: sm8250-mtp: fix reset line polarity
The driver for the codec, when resetting the chip, first drives the line
low, and then high. This means that the line is active low. Change the
annotation in the DTS accordingly.

76d21ffc5d arm64: dts: qcom: msm8996: fix sound card reset line polarity
When resetting the block, the reset line is being driven low and then
high, which means that the line in DTS should be annotated as "active
low". It will become important when wcd9335 driver will be converted
to gpiod API that respects declared line polarities.

9d561dc4e5 arm64: dts: qcom: sm8450: disable SDHCI SDR104/SDR50 on all boards
SDHCI on SM8450 HDK also has problems with SDR104/SDR50:

  mmc0: card never left busy state
  mmc0: error -110 whilst initialising SD card

so I think it is safe to assume this issue affects all SM8450 boards.
Move the quirk disallowing these modes to the SoC DTSI, to spare people
working on other boards the misery of debugging this issue.

We had to start passing in some information about audio requirements a

move all this type of information here for other protocols too.

Certain methods will be blocked on non-acquired outputs now, preventing
NULL pointer derefs from KMS driver bugs.

118e021b4b xfs: write page faults in iomap are not buffered writes
When we reserve a delalloc region in xfs_buffered_write_iomap_begin,
we mark the iomap as IOMAP_F_NEW so that the the write context
understands that it allocated the delalloc region.

If we then fail that buffered write, xfs_buffered_write_iomap_end()
checks for the IOMAP_F_NEW flag and if it is set, it punches out
the unused delalloc region that was allocated for the write.

The assumption this code makes is that all buffered write operations
that can allocate space are run under an exclusive lock (i_rwsem).
This is an invalid assumption: page faults in mmap()d regions call
through this same function pair to map the file range being faulted
and this runs only holding the inode->i_mapping->invalidate_lock in
shared mode.

IOWs, we can have races between page faults and write() calls that
fail the nested page cache write operation that result in data loss.
That is, the failing iomap_end call will punch out the data that
the other racing iomap iteration brought into the page cache. This
can be reproduced with generic/34[46] if we arbitrarily fail page
cache copy-in operations from write() syscalls.

Code analysis tells us that the iomap_page_mkwrite() function holds
the already instantiated and uptodate folio locked across the iomap
mapping iterations. Hence the folio cannot be removed from memory
whilst we are mapping the range it covers, and as such we do not
care if the mapping changes state underneath the iomap iteration
loop:

1. if the folio is not already dirty, there is no writeback races
   possible.
2. if we allocated the mapping (delalloc or unwritten), the folio
   cannot already be dirty. See #1.
3. If the folio is already dirty, it must be up to date. As we hold
   it locked, it cannot be reclaimed from memory. Hence we always
   have valid data in the page cache while iterating the mapping.
4. Valid data in the page cache can exist when the underlying
   mapping is DELALLOC, UNWRITTEN or WRITTEN. Having the mapping
   change from DELALLOC->UNWRITTEN or UNWRITTEN->WRITTEN does not
   change the data in the page - it only affects actions if we are
   initialising a new page. Hence #3 applies  and we don't care
   about these extent map transitions racing with
   iomap_page_mkwrite().
5. iomap_page_mkwrite() checks for page invalidation races
   (truncate, hole punch, etc) after it locks the folio. We also
   hold the mapping->invalidation_lock here, and hence the mapping
   cannot change due to extent removal operations while we are
   iterating the folio.

As such, filesystems that don't use bufferheads will never fail
the iomap_folio_mkwrite_iter() operation on the current mapping,
regardless of whether the iomap should be considered stale.

Further, the range we are asked to iterate is limited to the range
inside EOF that the folio spans. Hence, for XFS, we will only map
the exact range we are asked for, and we will only do speculative
preallocation with delalloc if we are mapping a hole at the EOF
page. The iterator will consume the entire range of the folio that
is within EOF, and anything beyond the EOF block cannot be accessed.
We never need to truncate this post-EOF speculative prealloc away in
the context of the iomap_page_mkwrite() iterator because if it
remains unused we'll remove it when the last reference to the inode
goes away.

Hence we don't actually need an .iomap_end() cleanup/error handling
path at all for iomap_page_mkwrite() for XFS. This means we can
separate the page fault processing from the complexity of the
.iomap_end() processing in the buffered write path. This also means
that the buffered write path will also be able to take the
mapping->invalidate_lock as necessary.

Pull cxl fixes from Dan Williams:
 "Several fixes for CXL region creation crashes, leaks and failures.

  This is mainly fallout from the original implementation of dynamic CXL
  region creation (instantiate new physical memory pools) that arrived
  in v6.0-rc1.

  Given the theme of "failures in the presence of pass-through decoders"
  this also includes new regression test infrastructure for that case.

  Summary:

   - Fix region creation crash with pass-through decoders

   - Fix region creation crash when no decoder allocation fails

   - Fix region creation crash when scanning regions to enforce the
     increasing physical address order constraint that CXL mandates

   - Fix a memory leak for cxl_pmem_region objects, track 1:N instead of

aa52994915 hwmon fixes for v6.1-rc4
Fix two regressions:
 
 - Commit 54cc3dbfc1 ("hwmon: (pmbus) Add regulator supply into macro")
   resulted in regulator undercount when disabling regulators. Revert it.
 
 - The thermal subsystem rework caused the scmi driver to no longer register
   with the thermal subsystem because index values no longer match.
   To fix the problem, the scmi driver now directly registers with the
   thermal subsystem, no longer through the hwmon core.

abef378c43 RDMA/mlx5: Change debug log level for remote access error syndromes
The mlx5 driver dumps the entire CQE buffer by default for few syndromes.
Some syndromes are expected due to the application behavior [ex:
MLX5_CQE_SYNDROME_REMOTE_ACCESS_ERR, MLX5_CQE_SYNDROME_REMOTE_OP_ERR and
MLX5_CQE_SYNDROME_LOCAL_PROT_ERR]. Hence, for these syndromes, the patch
converts the log level from KERN_WARNING to KERN_DEBUG. This enables the
application to get the CQE buffer dump by changing to KERN_DEBUG level
as and when needed.

b1599915f0 x86/cpufeatures: Move X86_FEATURE_CALL_DEPTH from bit 18 to bit 19 of word 11, to leave space for WIP X86_FEATURE_SGX_EDECCSSA bit
Reallocate a soft-cpufeatures bit allocated for call-depth tracking
code, which clashes with this recent KVM/SGX patch being worked on:

        KVM/VMX: Allow exposing EDECCSSA user leaf function to KVM guest

Instead of reallocating cpufeatures bits in evil merges, make the
allocation explicit.

9f2a1d9fb3 ext4: fix wrong return err in ext4_load_and_init_journal()
The return value is wrong in ext4_load_and_init_journal(). The local
variable 'err' need to be initialized before goto out. The original code
in __ext4_fill_super() is fine because it has two return values 'ret'
and 'err' and 'ret' is initialized as -EINVAL. After we factor out
ext4_load_and_init_journal(), this code is broken. So fix it by directly
returning -EINVAL in the error handler path.

17a0bc9bd6 ext4: fix BUG_ON() when directory entry has invalid rec_len
The rec_len field in the directory entry has to be a multiple of 4.  A
corrupted filesystem image can be used to hit a BUG() in
ext4_rec_len_to_disk(), called from make_indexed_dir().

The fix simply adds a call to ext4_check_dir_entry() to validate the
directory entry, returning -EFSCORRUPTED if the entry is invalid.
