When commanding chmod and chown on cifs&ksmbd, ksmbd allows it without file
permissions check. There is code to check it in settattr_prepare.
Instead of setting the inode directly, update the mode and uid/gid
through notify_change.

There is a race condition during shutdown in adf_disable_sriov() where
both the PF and the VF drivers are loaded on the host system.
The PF notifies a VF with a "RESTARTING" message due to which the VF
starts an asynchronous worker to stop and shutdown itself.
At the same time the PF calls pci_disable_sriov() which invokes the
remove() routine on the VF device driver triggering the shutdown flow
again.
This change fixes the problem by ensuring that the VF flushes the worker
that performs stop()/shutdown() before these two functions are called in
the remove(). To make sure that no additional PV/VF messages are
processed by the VF, interrupts are disabled before flushing the
workqueue.

All QAT GEN2 devices share the same register offset for masking interrupts,

Currently all the functions related to the activation of the PFVF
protocol, both on PF and VF, include the direction specific "vf2pf"
name.
Replace the existing naming schema with:
- a direction agnostic naming, that applies to both PF and VF, for the
function pointer ("pfvf")
- a direction specific naming schema for the implementations ("pf2vf" or
"vf2pf")
In particular this patch renames:
- adf_pf_enable_vf2pf_comms() in adf_enable_pf2vf_comms()
- enable_vf2pf_comms() in enable_pfvf_comms()

In the PF interrupt handler, the interrupt is disabled for a set of VFs
by writing to the interrupt source mask register, ERRMSK.
The interrupt is re-enabled in the bottom half handler by writing to the
same CSR. This is done through the functions enable_vf2pf_interrupts()
and disable_vf2pf_interrupts() which perform a read-modify-write
operation on the ERRMSK registers to mask and unmask the source of
interrupt.
There can be a race condition where the top half handler for one VF
interrupt runs just as the bottom half for another VF is about to
re-enable the interrupt. Depending on whether the top or bottom half
updates the CSR first, this would result either in a spurious interrupt
or in the interrupt not being re-enabled.
This patch protects the access of ERRMSK with a spinlock.
The functions adf_enable_vf2pf_interrupts() and
adf_disable_vf2pf_interrupts() have been changed to acquire a spin lock
before accessing and modifying the ERRMSK registers. These functions use
spin_lock_irqsave() to disable IRQs and avoid potential deadlocks.
In addition, the function adf_disable_vf2pf_interrupts_irq() has been
added. This uses spin_lock() and it is meant to be used in the top half
only.

There is a chance that the PFVF handler, adf_vf2pf_req_hndl(), runs
twice for the same request when multiple interrupts come simultaneously
from different VFs.
Since the source VF is identified by a positional bit set in the ERRSOU
registers and that is not cleared until the bottom half completes, new
top halves from other VFs may reschedule a second bottom half for
previous interrupts.
This patch solves the problem in the ISR handler by not considering
sources with already disabled interrupts (and processing pending), as
set in the ERRMSK registers.
Also, move some definitions where actually needed.

QAT GEN2 devices suffer from a defect where the MSI interrupt can be
sent multiple times.
If the second (spurious) interrupt is handled before the bottom half
handler runs, then the extra interrupt is effectively ignored because
the bottom half is only scheduled once.
However, if the top half runs again after the bottom half runs, this
will appear as a spurious PF to VF interrupt.
This can be avoided by checking the interrupt mask register in addition
to the interrupt source register in the interrupt handler.
This patch is based on earlier work done by Conor McLoughlin.

The omap-des and omap-sham drivers appear to have a similar issue.
Fix this by using spin_{,un}lock_bh() around device list access in all
the probe and remove functions.

omap_crypto_cleanup() currently copies data from sg to orig if either
copy flag is set. However OMAP_CRYPTO_SG_COPIED means that sg refers
to the same pages as orig, truncated to len bytes. There is no need
to copy in this case.
Only copy data if the OMAP_CRYPTO_DATA_COPIED flag is set.

This essentially reverts "block: remove the extra kobject reference in
bd_link_disk_holder". That commit dropped the extra reference because
the condition in the comment can't be true. But it turns out that
comment did not actually describe the problematic situation, so add
back the extra reference and document it properly.

This reverts commit a955318fe67e ("stmmac: align RX buffers"),
which breaks at least one platform (Nvidia Jetson-X1), causing
packet corruption. This is 100% reproducible, and reverting
the patch results in a working system again.
Given that it is "only" a performance optimisation, let's
return to a known working configuration until we can have a
good understanding of what is happening here.

We currently check for ret != 0 to indicate error, but '1' is a valid
return and just indicates that the allocation succeeded with a wrap.
Correct the check to be for < 0, like it was before the xarray
conversion.

Pull drm fixes from Dave Airlie:
"Regularly scheduled fixes. The ttm one solves a problem of GPU drivers
failing to load if debugfs is off in Kconfig, otherwise the i915 and
mediatek, and amdgpu fixes all fairly normal.
Nouveau has a couple of display fixes, but it has a fix for a
longstanding race condition in it's memory manager code, and the fix
mostly removes some code that wasn't working properly and has no
userspace users. This fix makes the diffstat kinda larger but in a
good (negative line-count) way.
core:
- fix drm_wait_vblank uapi copying bug
ttm:
- fix debugfs init when debugfs is off
amdgpu:
- vega10 SMU workload fix
- DCN VM fix
- DCN 3.01 watermark fix
amdkfd:

nouveau:
- ampere display fixes
- remove MM misfeature to fix a longstanding race condition

- tweaked display workaround for all PCHs
- eDP MSO pipe sanity for ADL-P fix
