Pull module updates from Petr Pavlu:
- Remove unnecessary module::args. Nowadays, no parameter-handling code
points into the module::args buffer. The last user of module::args in

The lid switch reports "close" but can miss the matching "open", leaving
_LID closed after resume. systemd-logind then suspends the system again
roughly every 35 seconds.
Reading the embedded controller's PSTA byte while _LID is stale shows that
bit 0x04 is set, which the DSDT treats as open. The DSDT returns the cached
LIDS byte from _LID. Its wake path aborts in RTEC on an unhandled
SystemCMOS region before copying PSTA to LIDS.
Initialize the lid state to open on resume, matching the existing quirk
for the Razer Blade Stealth 13 late 2019. With
button.lid_init_state=open, a physical close suspended once and resume
reported open without another suspend.

When a burst of packets is handed down to the driver, the driver defers
the doorbell to the end by setting txr->kick_pending = 1. The normal TX
path handles this, but the SW USO path can miss it if it returns
early.
If bnxt_sw_udp_gso_xmit runs but returns early with NETDEV_TX_BUSY and
txr->kick_pending was previously set to 1, then the TX queue can
stall because the driver wrote some BDs but never wrote the doorbell.
The device won't know to do the TX which would generate the completion
that would wake the queue back up.
Simplify bnxt_sw_udp_gso_xmit to set txr->kick_pending in its success
case and check the flag on return. The added check after
bnxt_sw_udp_gso_xmit returns ensures that any pending doorbells are
written handling both successful USO and any early returns, which
prevents the TX queue stall mentioned above.
This TX queue stall was observed on a production system with a netdev TX
watchdog informing about the queue stall.

now the following warning is observed:
tegra210-ope 2908000.processing-engine: Driver needs fixing: Unsorted
reg_defaults, sorting the copy
This warning occurs because register defaults in the structure
tegra210_mbdrc_reg_defaults are not specified in ascending order which
is required by regmap. Fix this by sorting the register defaults
according to their address. Note that in order to do this it is
necessary to replace the macro MBDRC_FILTER_REG_DEFAULTS with a per

Commit f234fdaae1ca ("ACPI: scan: Avoid registering platform devices
with resource overlaps") attempted to avoid platform device registration
errors due to overlaps of resources of the same type returned by the
same _CRS object in the ACPI tables. It did that by combining two or
more overlapping resources into one, but it went too far and also
caused resources that overlap completely to be combined which broke
the arm-cmn driver that expects two MMIO resources to be present for
each device it binds to and it expects those two resources to overlap
completely.
Address this issue by adding checks for completely overlapping
resources to acpi_platform_adjust_resources() and add a comment
explaining what is done there.

Port the LZX and XPRESS decompressors from the userspace
ntfs-3g-system-compression plugin (Eric Biggers,
https://github.com/ebiggers/ntfs-3g-system-compression) into the in-tree
NTFS driver under lib/, and adapt them to the kernel environment.
The upstream plugin implements WOF ("Windows Overlay Filesystem", a.k.a.
system compression / "Compact OS") decompression for the NTFS-3G FUSE
driver, and itself borrows the LZX/XPRESS decompressors that the same
author wrote for wimlib (https://wimlib.net/). The XPRESS and LZX
formats used here are identical to those used in WIM archives. This
commit is the kernel-side port that lets fs/ntfs/wof.c read
system-compressed files.
The library keeps the upstream subtable-based Huffman decoder (root
table + contiguous subtables decoded with MAKE_DECODE_TABLE_ENTRY()), so
long codewords only need one extra lookup instead of bit-by-bit tree
traversal. The ntfs_codec_ops interface exported to fs/ntfs/wof.c
(ntfs_lzx32k_codec_ops and ntfs_xpress{4k,8k,16k}_codec_ops) matches
what the WOF layer expects.
Modifications made while porting from the upstream plugin:
- Replace the variable LZX window order (2^15..2^21) with a fixed
32768-byte window, which is the only size WOF uses
- Simplify the bitstream helper:
- bitstream_ensure_bits() now guarantees 16 valid bits instead of the
carried-over 17-bit refill path from wimlib. Neither LZX (max
codeword length 16) nor XPRESS (max 15) needs more than 16 bits.
- Refactor codes to satisfy checkpatch.

An user reported a bug where he managed to evade group's quota
by changing a file's gid to a different group id the same user
belonged to, even though quotas were enforced on both gids and the
file's size was big enough to exceed the quota's hardlimit.
Commit eba0549bc7d1 replaced a capable() call by a
has_capability_noaudit() to prevent unnecessary selinux audit messages.
Turns out that both calls have slightly different semantics even though
their documentation seems similar. Where in a nutshell:
capable() - Tests the task's effective credentials
has_ns_capability_noaudit() - Tests the task's real credentials
This most of the time has no practical difference but in some cases like
changing attrs (specifically group id in this case) through a NFS client
this will allow the quota code to use XFS_QMOPT_FORCE_RES, effectively
bypassing quota accounting checks.
Using instead ns_capable_noaudit() should fix this issue and prevent
selinux audit messages.
This also fix the remaining calls to has_capability_noaudit()

When testing on very fast storage devices, I've observed writers using
io_uring creating many open zones with just a few kiB written to it,
which then don't get used. I tracked this down to multiple io_uring
helper threads finding a full zone in i_private, and then going on to
select a one, with the final one winning the race and leaving it in
i_private.
Fix this by dropping full zones from i_private as soon we find them,
checking cached for a cached zoned when a single writes needs a new zone,
and by keeping an existing cached zone in xfs_set_cached_zone when it
still has space available, dropping the newly found/allocated one
instead. This uses i_flags_lock as a low-level spinlock for short
hold times to avoid interactions with the ilock, which is used for
completions.

xfs_sync_sb_buf() holds sb/rtsb buffer locks across a synchronous
xfs_trans_commit(), which flushes the CIL push workqueue internally.
If shutdown occurs during the CIL push, xfs_buf_item_unpin() needs to
lock these buffers to fail them, causing a deadlock:
setlabel: holds buf lock -> flush_workqueue(xfs-cil)
CIL push worker: xfs_buf_item_unpin -> xfs_buf_lock(same buf)
Remove the xfs_trans_bhold() calls so that commit releases the buffer
locks normally. After the sync commit, re-acquire the buffers via
mp->m_sb_bp / mp->m_rtsb_bp for the on-disk writeback.
