Pull io_uring fixes from Jens Axboe:

 - Fix a typo in the mock_file help text

 - Fix a comment regarding IORING_SETUP_TASKRUN_FLAG in the
   io_uring.h UAPI header

 - Use READ_ONCE() for reading refill queue entries

 - Reject SEND_VECTORIZED for fixed buffer sends, as it isn't
   implemented. Currently this flag is silently ignored

   This is in preparation for making these work, but first we
   need a fixup so that older kernels will correctly reject them

 - Ensure "0" means default for the rx page size

A return type fix for ttm, a display fix for solomon, several misc fixes

possible build failure fix for dma-buf, a doc warning fix for sched, a

include/uapi/linux/dma-buf.h uses several macros from ioctl.h to define
its ioctl commands. However, it does not include ioctl.h itself. So,
if userspace source code tries to include the dma-buf.h file without
including ioctl.h, it can result in build failures.

Therefore, include ioctl.h in the dma-buf UAPI header.

Pull scheduler fixes from Ingo Molnar:

 - Fix zero_vruntime tracking when there's a single task running

 - Fix slice protection logic

 - Fix the ->vprot logic for reniced tasks

 - Fix lag clamping in mixed slice workloads

 - Fix objtool uaccess warning (and bug) in the
   !CONFIG_RSEQ_SLICE_EXTENSION case caused by unexpected un-inlining,
   which triggers with older compilers

 - Fix a comment in the rseq registration rseq_size bound check code

 - Fix a legacy RSEQ ABI quirk that handled 32-byte area sizes
   differently, which special size we now reached naturally and want to
   avoid. The visible ugliness of the new reserved field will be avoided
   the next time the RSEQ area is extended.

Sync with a recent liburing fix, which corrects the comment explaining
when the IORING_SETUP_TASKRUN_FLAG setup flag is valid to use. May be
use with COOP_TASKRUN or DEFER_TASKRUN, not useful without either of
this task_work mechanisms being used.

fb82437fdd8c ("PCI: Change capability register offsets to hex") incorrectly
converted the PCI_CAP_EXP_ENDPOINT_SIZEOF_V2 value from decimal 52 to hex
0x32:

  -#define PCI_CAP_EXP_ENDPOINT_SIZEOF_V2 52      /* v2 endpoints with link end here */
  +#define PCI_CAP_EXP_ENDPOINT_SIZEOF_V2 0x32    /* end of v2 EPs w/ link */

This broke PCI capabilities in a VMM because subsequent ones weren't
DWORD-aligned.

Change PCI_CAP_EXP_ENDPOINT_SIZEOF_V2 to the correct value of 0x34.

fb82437fdd8c was from Baruch Siach <baruch@tkos.co.il>, but this was not
Baruch's fault; it's a mistake I made when applying the patch.

Before rseq became extensible, its original size was 32 bytes even
though the active rseq area was only 20 bytes. This had the following
impact in terms of userspace ecosystem evolution:

* The GNU libc between 2.35 and 2.39 expose a __rseq_size symbol set
  to 32, even though the size of the active rseq area is really 20.
* The GNU libc 2.40 changes this __rseq_size to 20, thus making it
  express the active rseq area.
* Starting from glibc 2.41, __rseq_size corresponds to the
  AT_RSEQ_FEATURE_SIZE from getauxval(3).

This means that users of __rseq_size can always expect it to
correspond to the active rseq area, except for the value 32, for
which the active rseq area is 20 bytes.

Exposing a 32 bytes feature size would make life needlessly painful
for userspace. Therefore, add a reserved field at the end of the
rseq area to bump the feature size to 33 bytes. This reserved field
is expected to be replaced with whatever field will come next,
expecting that this field will be larger than 1 byte.

The effect of this change is to increase the size from 32 to 64 bytes
before we actually have fields using that memory.

Clarify the allocation size and alignment requirements in the struct
rseq uapi comment.

Change the value returned by getauxval(AT_RSEQ_ALIGN) to return the
value of the active rseq area size rounded up to next power of 2, which
guarantees that the rseq structure will always be aligned on the nearest
power of two large enough to contain it, even as it grows. Change the
alignment check in the rseq registration accordingly.

This will minimize the amount of ABI corner-cases we need to document
and require userspace to play games with. The rule stays simple when
__rseq_size != 32:

  #define rseq_field_available(field)	(__rseq_size >= offsetofend(struct rseq_abi, field))
