- 'perf record --per-thread' mode doesn't have the CPU mask setup, so it
   can use it to figure out the number of mmaps, fix it.
 
 - Fix segfault accessing sample_id xyarray out of bounds, noticed while
   using Intel PT where we have a dummy event to capture text poke perf
   metadata events and we mixup the set of CPUs specified by the user
   with the all CPUs map needed for text poke.
 
 - Fix 'perf bench numa' to check if CPU used to bind task is online.
 
 - Fix 'perf bench numa' usage of affinity for machines with more than
   1000 CPUs.

66dd346b84 nvme-pci: disable namespace identifiers for Qemu controllers
Qemu unconditionally reports a UUID, which depending on the qemu version
is either all-null (which is incorrect but harmless) or contains a single
bit set for all controllers.  In addition it can also optionally report
a eui64 which needs to be manually set.  Disable namespace identifiers
for Qemu controlles entirely even if in some cases they could be set
correctly through manual intervention.

00ff400e6d nvme: add a quirk to disable namespace identifiers
Add a quirk to disable using and exporting namespace identifiers for
controllers where they are broken beyond repair.

The most directly visible problem with non-unique namespace identifiers
is that they break the /dev/disk/by-id/ links, with the link for a
supposedly unique identifier now pointing to one of multiple possible
namespaces that share the same ID, and a somewhat random selection of
which one actually shows up.

b42b6f4485 nvme: don't print verbose errors for internal passthrough requests
Use the RQF_QUIET flag to skip the newly added verbose error reporting,
and set the flag in __nvme_submit_sync_cmd, which is used for most
internal passthrough requests where we do expect errors (e.g. due to
probing for optional functionality).  This is similar to what the SCSI
verbose error logging does.

7dd06a2548 dm: allow dm_accept_partial_bio() for dm_io without duplicate bios
The intent behind commit e6fc9f62ce ("dm: flag clones created by
__send_duplicate_bios") was to formally disallow the use of
dm_accept_partial_bio() where it simply isn't possible -- due to
constraint that multiple bios cannot meaningfully update a shared
tio->len_ptr.

But that commit went too far and disallowed the case where "abormal"
IO (e.g. WRITE_ZEROES) is only using a single bio.  Fix this by
not marking a dm_io with a single dm_target_io (and bio), that happens
to be created by __send_duplicate_bios, as DM_TIO_IS_DUPLICATE_BIO.
Also remove 'unsigned *len' parameter from alloc_multiple_bios().

This commit fixes a dm_accept_partial_bio() BUG_ON() with dm-zoned
when a WRITE_ZEROES bio is issued.

Fixes: 655f3aad7a ("dm: switch dm_target_io booleans over to proper flags")

b3d4650d82 VFS: filename_create(): fix incorrect intent.
When asked to create a path ending '/', but which is not to be a
directory (LOOKUP_DIRECTORY not set), filename_create() will never try
to create the file.  If it doesn't exist, -ENOENT is reported.

However, it still passes LOOKUP_CREATE|LOOKUP_EXCL to the filesystems
->lookup() function, even though there is no intent to create.  This is
misleading and can cause incorrect behaviour.

If you try

   ln -s foo /path/dir/

where 'dir' is a directory on an NFS filesystem which is not currently
known in the dcache, this will fail with ENOENT.

But as the name is not in the dcache, nfs_lookup gets called with
LOOKUP_CREATE|LOOKUP_EXCL and so it returns NULL without performing any
lookup, with the expectation that a subsequent call to create the target
will be made, and the lookup can be combined with the creation.  In the
case with a trailing '/' and no LOOKUP_DIRECTORY, that call is never
made.  Instead filename_create() sees that the dentry is not (yet)
positive and returns -ENOENT - even though the directory actually
exists.

So only set LOOKUP_CREATE|LOOKUP_EXCL if there really is an intent to
create, and use the absence of these flags to decide if -ENOENT should
be returned.

Note that filename_parentat() is only interested in LOOKUP_REVAL, so we
split that out and store it in 'reval_flag'.  __lookup_hash() then gets
reval_flag combined with whatever create flags were determined to be
needed.

ARM: config: Update Gemini defconfig
The Gemini defconfig needs to be updated due to DSA driver
Kconfig changes in the v5.18 merge window:
CONFIG_NET_DSA_REALTEK_SMI is now behind
CONFIG_NET_DSA_REALTEK and the desired DSA switch need
to be selected explicitly with
CONFIG_NET_DSA_REALTEK_RTL8366RB.

Take this opportunity to update some other minor config
options:

- CONFIG_MARVELL_PHY moved around because of Kconfig
  changes.

- CONFIG_SENSORS_DRIVETEMP should be selected since is
  regulates the system critical alert temperature on
  some devices, which is nice if it is handled even
  if initramfs or root fails to mount.

This became an unexpectedly large pull request due to various
 regression fixes in the previous kernels.
 
 The majority of fixes are a series of patches to address the
 regression at probe errors in devres'ed drivers, while there are
 yet more fixes for the x86 SG allocations and for USB-audio
 buffer management.  In addition, a few HD-audio quirks and other
 small fixes are found.

f58faed7fb perf bench: Fix numa bench to fix usage of affinity for machines with #CPUs > 1K
The 'perf bench numa' testcase fails on systems with more than 1K CPUs.

Testcase: perf bench numa mem -p 1 -t 3 -P 512 -s 100 -zZ0qcm --thp  1

Snippet of code:

  <<>>
  perf: bench/numa.c:302: bind_to_node: Assertion `!(ret)' failed.
  Aborted (core dumped)
  <<>>

bind_to_node() uses "sched_getaffinity" to save the original cpumask and
this call is returning EINVAL ((invalid argument).

This happens because the default mask size in glibc is 1024.  To
overcome this 1024 CPUs mask size limitation of cpu_set_t, change the
mask size using the CPU_*_S macros ie, use CPU_ALLOC to allocate
cpumask, CPU_ALLOC_SIZE for size.

Apart from fixing this for "orig_mask", apply same logic to "mask" as
well which is used to setaffinity so that mask size is large enough to
represent number of possible CPU's in the system.

sched_getaffinity is used in one more place in perf numa bench. It is in
"bind_to_cpu" function. Apply the same logic there also. Though
currently no failure is reported from there, it is ideal to change
getaffinity to work with such system configurations having CPU's more
than default mask size supported by glibc.

Also fix "sched_setaffinity" to use mask size which is large enough to
represent number of possible CPU's in the system.

Fixed all places where "bind_cpumask" which is part of "struct
thread_data" is used such that bind_cpumask works in all configuration.

8cb7a188ac perf bench: Fix numa testcase to check if CPU used to bind task is online
Perf numa bench test fails with error:

Testcase:

  ./perf bench numa mem -p 2 -t 1 -P 1024 -C 0,8 -M 1,0 -s 20 -zZq --thp  1 --no-data_rand_walk

Failure snippet:

<<>>
  Running 'numa/mem' benchmark:

  # Running main, "perf bench numa numa-mem -p 2 -t 1 -P 1024 -C 0,8 -M 1,0 -s 20 -zZq --thp 1 --no-data_rand_walk"

  perf: bench/numa.c:333: bind_to_cpumask: Assertion `!(ret)' failed.
<<>>

The Testcases uses CPU's 0 and 8. In function "parse_setup_cpu_list",
There is check to see if cpu number is greater than max cpu's possible
in the system ie via "if (bind_cpu_0 >= g->p.nr_cpus || bind_cpu_1 >=
g->p.nr_cpus) {".

But it could happen that system has say 48 CPU's, but only number of
online CPU's is 0-7. Other CPU's are offlined. Since "g->p.nr_cpus" is
48, so function will go ahead and set bit for CPU 8 also in cpumask (
td->bind_cpumask).

bind_to_cpumask function is called to set affinity using
sched_setaffinity and the cpumask. Since the CPU8 is not present, set
affinity will fail here with EINVAL.

Fix this issue by adding a check to make sure that, CPU's provided in
the input argument values are online before proceeding further and skip
the test. For this, include new helper function "is_cpu_online" in
"tools/perf/util/header.c".

Since "BIT(x)" definition will get included from header.h, remove
that from bench/numa.c

23cfe941b5 rtnetlink: Fix handling of disabled L3 stats in RTM_GETSTATS replies
When L3 stats are disabled, rtnl_offload_xstats_get_size_stats() returns
size of 0, which is supposed to be an indication that the corresponding
attribute should not be emitted. However, instead, the current code
reserves a 0-byte attribute.

The reason this does not show up as a citation on a kasan kernel is that
netdev_offload_xstats_get(), which is supposed to fill in the data, never
ends up getting called, because rtnl_offload_xstats_get_stats() notices
that the stats are not actually used and skips the call.

Thus a zero-length IFLA_OFFLOAD_XSTATS_L3_STATS attribute ends up in a
response, confusing the userspace.

Fix by skipping the L3-stats related block in rtnl_offload_xstats_fill().

00fa91bc9c net: dsa: felix: fix tagging protocol changes with multiple CPU ports
When the device tree has 2 CPU ports defined, a single one is active
(has any dp->cpu_dp pointers point to it). Yet the second one is still a
CPU port, and DSA still calls ->change_tag_protocol on it.

On the NXP LS1028A, the CPU ports are ports 4 and 5. Port 4 is the
active CPU port and port 5 is inactive.

After the following commands:

 # Initial setting
 cat /sys/class/net/eno2/dsa/tagging
 ocelot
 echo ocelot-8021q > /sys/class/net/eno2/dsa/tagging
 echo ocelot > /sys/class/net/eno2/dsa/tagging

traffic is now broken, because the driver has moved the NPI port from
port 4 to port 5, unbeknown to DSA.

The problem can be avoided by detecting that the second CPU port is
unused, and not doing anything for it. Further rework will be needed
when proper support for multiple CPU ports is added.

Treat this as a bug and prepare current kernels to work in single-CPU
mode with multiple-CPU DT blobs.

9e02977bfa dma-direct: avoid redundant memory sync for swiotlb
When we looked into FIO performance with swiotlb enabled in VM, we found
swiotlb_bounce() is always called one more time than expected for each DMA
read request.

It turns out that the bounce buffer is copied to original DMA buffer twice
after the completion of a DMA request (one is done by in
dma_direct_sync_single_for_cpu(), the other by swiotlb_tbl_unmap_single()).
But the content in bounce buffer actually doesn't change between the two
rounds of copy. So, one round of copy is redundant.

Pass DMA_ATTR_SKIP_CPU_SYNC flag to swiotlb_tbl_unmap_single() to
skip the memory copy in it.

This fix increases FIO 64KB sequential read throughput in a guest with
swiotlb=force by 5.6%.

4593c1b6d1 drm/amdgpu: Enable gfxoff quirk on MacBook Pro
Enabling gfxoff quirk results in perfectly usable graphical user
interface on MacBook Pro (15-inch, 2019) with Radeon Pro Vega 20 4 GB.

Without the quirk, X server is completely unusable as every few seconds
there is gpu reset due to ring gfx timeout.

887f75cfd0 drm/amdgpu: Ensure HDA function is suspended before ASIC reset
DP/HDMI audio on AMD PRO VII stops working after S3:
[  149.450391] amdgpu 0000:63:00.0: amdgpu: MODE1 reset
[  149.450395] amdgpu 0000:63:00.0: amdgpu: GPU mode1 reset

...
[  155.432975] snd_hda_intel 0000:63:00.1: CORB reset timeout#2, CORBRP = 65535

The offending commit is daf8de0874 ("drm/amdgpu: always reset the asic in
suspend (v2)"). Commit 34452ac303 ("drm/amdgpu: don't use BACO for
reset in S3 ") doesn't help, so the issue is something different.

Assuming that to make HDA resume to D0 fully realized, it needs to be
successfully put to D3 first. And this guesswork proves working, by
moving amdgpu_asic_reset() to noirq callback, so it's called after HDA
function is in D3.

e4f1541caf drm/amd/display: don't ignore alpha property on pre-multiplied mode
"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as
documented in supported_modes of drm_plane_create_blend_mode_property():
https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c

In this mode, both 'pixel alpha' and 'plane alpha' participate in the
calculation, as described by the pixel blend mode formula in KMS/DRM
documentation:

out.rgb = plane_alpha * fg.rgb +
          (1 - (plane_alpha * fg.alpha)) * bg.rgb

Considering the blend config mechanisms we have in the driver so far,
the alpha mode that better fits this blend mode is the
_PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain
is the plane alpha (global_alpha).

With this change, alpha property stops to be ignored. It also addresses
Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1734

v2:
 * keep the 8-bit value for global_alpha_value (Nicholas)
 * correct the logical ordering for combined global gain (Nicholas)
 * apply to dcn10 too (Nicholas)

a668cc07f9 perf tools: Fix segfault accessing sample_id xyarray
perf_evsel::sample_id is an xyarray which can cause a segfault when
accessed beyond its size. e.g.

  # perf record -e intel_pt// -C 1 sleep 1
  Segmentation fault (core dumped)
  #

That is happening because a dummy event is opened to capture text poke
events accross all CPUs, however the mmap logic is allocating according
to the number of user_requested_cpus.

In general, perf sometimes uses the evsel cpus to open events, and
sometimes the evlist user_requested_cpus. However, it is not necessary
to determine which case is which because the opened event file
descriptors are also in an xyarray, the size of whch can be used
to correctly allocate the size of the sample_id xyarray, because there
is one ID per file descriptor.

Note, in the affected code path, perf_evsel fd array is subsequently
used to get the file descriptor for the mmap, so it makes sense for the
xyarrays to be the same size there.

Fixes: 246eba8e90 ("perf tools: Add support for PERF_RECORD_TEXT_POKE")
