This patch enables the LMT line for a PF/VF by setting the
LMT_ENA bit in the APR_LMT_MAP_ENTRY_S structure.
Additionally, it simplifies the logic for calculating the
LMTST table index by consistently using the maximum
number of hw supported VFs (i.e., 256).

After freed the tipc_crypto tx by delete namespace, tipc_aead_encrypt_done

ip netns exec ns1 tipc node set key this_is_a_master_key master
ip netns exec ns1 tipc bearer disable media eth dev veth1
ip netns del ns1
The key of reproduction is that, simd_aead_encrypt is interrupted, leading
to crypto_simd_usable() return false. Thus, the cryptd_queue_worker is
triggered, and the tipc_crypto tx will be visited.
tipc_disc_timeout

cryptd_aead_encrypt_enqueue

net_sched: Fix HFSC qlen/backlog accounting bug and add selftest
This series addresses a long-standing bug in the HFSC qdisc where queue length
and backlog accounting could become inconsistent if a packet is dropped during
a peek-induced dequeue operation, and adds a corresponding selftest to tc-testing.

This test reproduces a scenario where HFSC queue length and backlog accounting
can become inconsistent when a peek operation triggers a dequeue and possible
drop before the parent qdisc updates its counters. The test sets up a DRR root
qdisc with an HFSC class, netem, and blackhole children, and uses Scapy to
inject a packet. It helps to verify that HFSC correctly tracks qlen and backlog
even when packets are dropped during peek-induced dequeue.

When enqueuing the first packet to an HFSC class, hfsc_enqueue() calls the
child qdisc's peek() operation before incrementing sch->q.qlen and
sch->qstats.backlog. If the child qdisc uses qdisc_peek_dequeued(), this may
trigger an immediate dequeue and potential packet drop. In such cases,
qdisc_tree_reduce_backlog() is called, but the HFSC qdisc's qlen and backlog
have not yet been updated, leading to inconsistent queue accounting. This
can leave an empty HFSC class in the active list, causing further
consequences like use-after-free.
This patch fixes the bug by moving the increment of sch->q.qlen and
sch->qstats.backlog before the call to the child qdisc's peek() operation.
This ensures that queue length and backlog are always accurate when packet
drops or dequeues are triggered during the peek.

When applying a recent commit to the <uapi/linux/perf_event.h>
header I noticed that we have accumulated quite a bit of
historic noise in this header, so do a bit of spring cleaning:
- Define bitfields in a vertically aligned fashion, like
perf_event_mmap_page::capabilities already does. This
makes it easier to see the distribution and sizing of
bits within a word, at a glance. The following is much
more readable:
__u64 cap_bit0 : 1,
cap_bit0_is_deprecated : 1,
cap_user_rdpmc : 1,
cap_user_time : 1,
cap_user_time_zero : 1,
cap_user_time_short : 1,
cap_____res : 58;
Than:
__u64 cap_bit0:1,
cap_bit0_is_deprecated:1,
cap_user_rdpmc:1,
cap_user_time:1,
cap_user_time_zero:1,
cap_user_time_short:1,
cap_____res:58;
So convert all bitfield definitions from the latter style to the
former style.
- Fix typos and grammar
- Fix capitalization
- Remove whitespace noise
- Harmonize the definitions of various generations and groups of
PERF_MEM_ ABI values.
- Vertically align all definitions and assignments to the same
column (48), as the first definition (enum perf_type_id),
throughout the entire header.
- And in general make the code and comments to be more in sync
with each other and to be more readable overall.
No change in functionality.
Copy the changes over to tools/include/uapi/linux/perf_event.h.

We are no longer calling gfs2_find_jhead() on the same log twice, so
there is no more reason for keeping the log contents cached across those
calls. In addition, log head lookup and log header writing didn't go
through the same address space and so the caching wasn't even fully
working, anyway.

Currently at mount time, the recovery code looks up the current log head
and, if necessary, replays the log and writes a recovery header to
indicate that the log is clean. It does that for each log that may need
recovery. We also know that our own log will always be checked as part
of that process. Then, the mount code looks up the log head of our own
log again.
The double log head lookup can be costly, but more importantly, it is
unnecessary because we can trivially compute the position of the log
head after recovery; all we need to do for that is bump the position and
lh_sequence by one when writing a recovery header.
With that in mind, move the call to gfs2_log_pointers_init() into
gfs2_recover_func() and get rid of the double lookup in
gfs2_make_fs_rw().

Before this change, the log head lookup code in freeze_go_xmote_bh()
didn't update sdp->sd_log_flush_head. This is now fixed, but the code
in freeze_go_xmote_bh() appears to be pretty useless in the first place:
on a frozen filesystem, the log head will not change.

Commit 8d391972ae2d ("gfs2: Remove __gfs2_writepage()") changed the log
flush code in gfs2_ail1_start_one() to call aops->writepages() instead
of aops->writepage(). For jdata inodes, this means that we will now try
to reserve log space and start a transaction before we can determine
that the pages in question have already been journaled. When this
happens in the context of gfs2_logd(), it can now appear that not enough
log space is available for freeing up log space, and we will lock up.
Fix that by issuing journal writes directly instead of going through
aops->writepages() in the log flush code.

__get_log_header() was using crc32_le_shift() to update a CRC with four
zero bytes. However, this is about 5x slower than just CRC'ing four
zero bytes in the normal way. Just do that instead.
(We could instead make crc32_le_shift() faster on short lengths. But
all its callers do just fine without it, so I'd like to just remove it.)

Since commit eb65540aa9fc ("iomap: warn on zero range of a post-eof
folio"), iomap_zero_range() warns when asked to zero a folio beyond eof.
The warning triggers on the following code path:
gfs2_fallocate(FALLOC_FL_PUNCH_HOLE | FALLOC_FL_KEEP_SIZE)
__gfs2_punch_hole()
gfs2_block_zero_range()
iomap_zero_range()
In __gfs2_punch_hole(), gfs2 zeroes out partial folios at the beginning
and at the end of the specified range, whether those folios are beyond
eof or not. This may add folios to the page cache which are entirely
beyond eof, which isn't of any use. Avoid that by truncating the range
to zero out at eof.

Generally PASID support requires ACS settings that usually create
single device groups, but there are some niche cases where we can get
multi-device groups and still have working PASID support. The primary
issue is that PCI switches are not required to treat PASID tagged TLPs
specially so appropriate ACS settings are required to route all TLPs to
the host bridge if PASID is going to work properly.
pci_enable_pasid() does check that each device that will use PASID has
the proper ACS settings to achieve this routing.
However, no-PASID devices can be combined with PASID capable devices
within the same topology using non-uniform ACS settings. In this case
the no-PASID devices may not have strict route to host ACS flags and
end up being grouped with the PASID devices.
This configuration fails to allow use of the PASID within the iommu
core code which wrongly checks if the no-PASID device supports PASID.
Fix this by ignoring no-PASID devices during the PASID validation. They
will never issue a PASID TLP anyhow so they can be ignored.

SPI and I2C into the tas2781_hda lib
Calibration data getting function for SPI and I2C HDA drivers are almost
same, which read the calibration data from UEFI. To put them into
tas2781_hda lib for code cleanup is more reasonable than to still keep
them in the codec driver. For tas2781 codec driver, there're two different
sources for calibrated data, one is from bin file, generated in factory
test, requested and read in codec driver side; the other is from user
space during device bootup.

SINK_COUNT_ESI read
Due to a problem in the iTBT DP-in adapter's firmware the sink on a TBT
link may get disconnected inadvertently if the SINK_COUNT_ESI and the
DP_LINK_SERVICE_IRQ_VECTOR_ESI0 registers are read in a single AUX
transaction. Work around the issue by reading these registers in
separate transactions.
The issue affects MTL+ platforms and will be fixed in the DP-in adapter
firmware, however releasing that firmware fix may take some time and is
not guaranteed to be available for all systems. Based on this apply the
workaround on affected platforms.
See HSD #13013007775.

When attempting to use an archive file, such as APEX on android,
as a file-backed mount source, it fails because EROFS image within
the archive file does not start at offset 0. As a result, a loop
or a dm device is still needed to attach the image file at an
appropriate offset first. Similarly, if an EROFS image within a
block device does not start at offset 0, it cannot be mounted
directly either.
To address this issue, this patch adds a new mount option `fsoffset=x'
to accept a start offset for the primary device. The offset should be
aligned to the block size. EROFS will add this offset before performing
read requests.

This violates NAPI rules, because after napi_complete_done(),
current thread lost napi ownership.
Move the test against POLL_MODE before the napi_complete_done().

I found that rename fails after cifs mount due to update of
lookup_one_qstr_excl().
mv a/c b/
mv: cannot move 'a/c' to 'b/c': No such file or directory
In order to rename to a new name regardless of whether the dentry is
negative, we need to get the dentry through lookup_one_qstr_excl().
So It will not return error if the name doesn't exist.

Subsystem rstat locks are dynamically allocated per-cpu. It was discovered
that a panic can occur during this allocation when the lock size is zero.
This is the case on non-smp systems, since arch_spinlock_t is defined as an
empty struct. Prevent this allocation when !CONFIG_SMP by adding a
pre-processor conditional around the affected block.

If a shorter than assumed transfer was seen, a partial buffer will have
been filled. For that case it isn't sane to attempt to fill more into
the bundle before posting a completion, as that will cause a gap in
the received data.
Check if the iterator has hit zero and only allow to continue a bundle
operation if that is the case.
Also ensure that for putting finished buffers, only the current transfer
is accounted. Otherwise too many buffers may be put for a short transfer.
