Pull io_uring fixes from Jens Axboe:
- When PF_NO_SETAFFINITY was removed for io-wq threads, we kind of
forgot about the SQPOLL thread. Remove it there as well, there's even
less of a reason to set it there (Michal)
- Fixup a confusing 'ret' setting (Li)
- When MSG_RING is used to send a direct descriptor to another ring,
it's possible to have it allocate it on the target ring rather than
provide a specific index for it. If this is done, return the chosen
value in the CQE, like we would've done locally (Pavel)
- Fix a regression in this series on huge page bvec collapsing (Pavel)

When running as non-root the following error is seen in turbostat:

turbostat and the man page have information on how to avoid other

Provide better /dev/cpu_dma_latency warnings that provide instructions on
how to avoid the error, and update the man page.

Before commit bdc1ddad3e5f ("compat_ioctl: block: move
blkdev_compat_ioctl() into ioctl.c"), the config BLOCK_COMPAT was used to
include compat_ioctl.c into the kernel build. With this commit, the code
is moved into ioctl.c and included with the config COMPAT. So, since then,
the config BLOCK_COMPAT has no effect and any further purpose.
Remove this obsolete config BLOCK_COMPAT.

Mark reports an issue with the recent patches coalescing compound pages
while registering them in io_uring. The reason is that we try to drop
excessive references with folio_put_refs(), but pages were acquired
with pin_user_pages(), which has extra accounting and so should be put
down with matching unpin_user_pages() or at least gup_put_folio().
As a fix unpin_user_pages() all but first page instead, and let's figure
out a better API after.

msg_ring requests transferring files support auto index selection via
IORING_FILE_INDEX_ALLOC, however they don't return the selected index
to the target ring and there is no other good way for the userspace to
know where is the receieved file.
Return the index for allocated slots and 0 otherwise, which is
consistent with other fixed file installing requests.

[Why]
In USB4 DP tunneling, it's possible to have this scenario that
the path becomes unavailable and CM tears down the path a little bit late.
So, in this case, the HPD is high but fails to read any DPCD register.
That causes the link connection type to be set to sst.
And not all sinks are removed behind the MST branch.
[How]
Restore the link connection type if it fails to read DPCD register.

[WHY]
Hot plugging and then hot unplugging leads to k1 and k2 values to
change, as signal is detected as a virtual signal on hot unplug. Writing
these values to OTG_PIXEL_RATE_DIV register might cause primary display
to blank (known hw bug).
[HOW]
No longer write k1 and k2 values to register if signal is virtual, we
have safe guards in place in the case that k1 and k2 is unassigned so
that an unknown value is not written to the register either.

While using iostat for raid, I observed very strange 'await'
occasionally, and turns out it's due to that 'ios' and 'sectors' is
counted in bdev_start_io_acct(), while 'nsecs' is counted in
bdev_end_io_acct(). I'm not sure why they are ccounted like that
but I think this behaviour is obviously wrong because user will get
wrong disk stats.
Fix the problem by counting 'ios' and 'sectors' when io is done, like
what rq-based device does.

An nvme target ->queue_response() operation implementation may free the
request passed as argument. Such implementation potentially could result
in a use after free of the request pointer when percpu_ref_put() is
called in nvmet_req_complete().
Avoid such problem by using a local variable to save the sq pointer
before calling __nvmet_req_complete(), thus avoiding dereferencing the
req pointer after that function call.

For non in-capsule writes we reuse the request pdu space for a h2cdata
pdu in order to avoid over allocating space (either preallocate or
dynamically upon receving an r2t pdu). However if the request times out
the core expects to find the opcode in the start of the request, which
we override.
In order to prevent that, without sacrificing additional 24 bytes per
request, we just use the tail of the command pdu space instead (last
24 bytes from the 72 bytes command pdu). That should make the command
opcode always available, and we get away from allocating more space.
If in the future we would need the last 24 bytes of the nvme command
available we would need to allocate a dedicated space for it in the
request, but until then we can avoid doing so.
