The pci_save_state() call in vmd_suspend() can be performed by
pci_pm_suspend_irq(). This also allows VMD to benefit from the call into
pci_prepare_to_sleep().
The pci_restore_state() call in vmd_resume() was restoring state after
pci_pm_resume()::pci_restore_standard_config() had already restored state.
It's also been suspected that the config state should have been restored
before re-requesting IRQs instead of afterwards.
Remove the pci_save_state()/pci_restore_state() calls in
vmd_suspend()/vmd_resume() to allow proper flow through generic PCI core
Power Management code.

If riov and wiov are both defined and they point to different
objects, only riov is initialized. If the wiov is not initialized
by the caller, the function fails returning -EINVAL and printing
"Readable desc 0x... after writable" error message.
This issue happens when descriptors have both readable and writable
buffers (eg. virtio-blk devices has virtio_blk_outhdr in the readable
buffer and status as last byte of writable buffer) and we call
__vringh_iov() to get both type of buffers in two different iovecs.
Let's replace the 'else if' clause with 'if' to initialize both
riov and wiov if they are not NULL.
As checkpatch pointed out, we also avoid crashing the kernel
when riov and wiov are both NULL, replacing BUG() with WARN_ON()
and returning -EINVAL.

set_map() is used by mlx5 vdpa to create a memory region based on the
address map passed by the iotlb argument. If we get successive calls, we
will destroy the current memory region and build another one based on
the new address mapping. We also need to setup the hardware resources
since they depend on the memory region.
If these calls happen before DRIVER_OK, It means that driver VQs may
also not been setup and we may not create them yet. In this case we want
to avoid setting up the other resources and defer this till we get
DRIVER OK.

An architecture may restrict host access to guest memory,
e.g. IBM s390 Secure Execution or AMD SEV.
Provide a new Kconfig entry the architecture can select,
CONFIG_ARCH_HAS_RESTRICTED_VIRTIO_MEMORY_ACCESS, when it provides
the arch_has_restricted_virtio_memory_access callback to advertise
to VIRTIO common code when the architecture restricts memory access
from the host.
The common code can then fail the probe for any device where
VIRTIO_F_ACCESS_PLATFORM is required, but not set.

Pull io_uring updates from Jens Axboe:
"A mix of fixes and a few stragglers. In detail:
- Revert the bogus __read_mostly that we discussed for the initial
pull request.
- Fix a merge window regression with fixed file registration error
path handling.
- Fix io-wq numa node affinities.
- Series abstracting out an io_identity struct, making it both easier
to see what the personality items are, and also easier to to adopt
more. Use this to cover audit logging.
- Fix for read-ahead disabled block condition in async buffered
reads, and using single page read-ahead to unify what
generic_file_buffer_read() path is used.

When the passed token is longer than 4032 bytes, the remaining part
of the token must be copied from the rqstp->rq_arg.pages. But the
copy must make sure it happens in a consecutive way.
With the existing code, the first memcpy copies 'length' bytes from
argv->iobase, but since the header is in front, this never fills the
whole first page of in_token->pages.
The mecpy in the loop copies the following bytes, but starts writing at
the next page of in_token->pages. This leaves the last bytes of page 0
unwritten.
Symptoms were that users with many groups were not able to access NFS
exports, when using Active Directory as the KDC.

Its possible that using AUTH_SYS and mountd manage-gids option a
user may hit the 8k RPC channel buffer limit. This have been observed
on field, causing unanswered RPCs on clients after mountd fails to
write on channel :
rpc.mountd[11231]: auth_unix_gid: error writing reply
Userland nfs-utils uses a buffer size of 32k (RPC_CHAN_BUF_SIZE), so
lets match those two.
