After commit 936e4d49ecbc ("Input: atkbd - skip ATKBD_CMD_GETID in
translated mode") not only the getid command is skipped, but also
the de-activating of the keyboard at the end of atkbd_probe(), potentially
re-introducing the problem fixed by commit be2d7e4233a4 ("Input: atkbd -
fix multi-byte scancode handling on reconnect").
Make sure multi-byte scancode handling on reconnect is still handled
correctly by not skipping the atkbd_deactivate() call.

After commit 936e4d49ecbc ("Input: atkbd - skip ATKBD_CMD_GETID in
translated mode") the keyboard on Dell XPS 13 9350 / 9360 / 9370 models
has stopped working after a suspend/resume.
The problem appears to be that atkbd_probe() fails when called
from atkbd_reconnect() on resume, which on systems where
ATKBD_CMD_GETID is skipped can only happen by ATKBD_CMD_SETLEDS
failing. ATKBD_CMD_SETLEDS failing because ATKBD_CMD_GETID was
skipped is weird, but apparently that is what is happening.
Fix this by also skipping ATKBD_CMD_SETLEDS when skipping
ATKBD_CMD_GETID.

UAPI Changes:
- Only allow a single user-fence per exec / bind.
The reason for this clarification fix is a limitation in the implementation
which can be lifted moving forward, if needed.
Driver Changes:
- A crash fix
- A fix for an assert due to missing mem_acces ref
- Only allow a single user-fence per exec / bind.
- Some sparse warning fixes
- Two fixes for compilation failures on various odd
combinations of gcc / arch pointed out on LKML.
- Fix a fragile partial allocation pointed out on LKML.
Cross-driver Change:
- A sysfs ABI documentation warning fix
This also touches i915 and is acked by i915 maintainers.

This reverts commit abe2023b4cea192ab266b351fd38dc9dbd846df0.
Changing the locking order means that scheduler/msm_job_run() can race
with the recovery kthread worker, with the result that the GPU gets an
extra runpm get when we are trying to power it off. Leaving the GPU in
an unrecovered state.
I'll need to come up with a different scheme for appeasing lockdep.

During the testing of Gnome on Qualcomm Robotics platform screen
corruption has been observed. Lowering GPU's highest_bank_bit from 14 to
13 seems to fix the screen corruption.
Note, the MDSS and DPU drivers use HBB=1 (which maps to the
highest_bank_bit = 14). So this change merely works around the UBWC
swizzling issue on this platform until the real cause is found.

The original code didn't update the firmware version if the
"next slot" of the AFI register isn't zero or if the
"current slot" field is zero; in those cases it assumed
that a reset was needed.
However, the NVMe specification doesn't exclude the possibility that
the "next slot" value is equal to the "current slot" value,
meaning that the same firmware slot will be activated after performing
a controller level reset; in this case a reset is clearly not
necessary and we can safely update the firmware version.
Modify the code so the kernel will report that a Controller Level Reset
is needed only in the following cases:
1) If the "current slot" field is zero. This is invalid and means that
something is wrong, a reset is needed.
or
2) if the "next slot" field isn't zero AND it's not equal to the
"current slot" value. This means that at the next reset a different
firmware slot will be activated.

In the arm random config file, kconfig option 'CONFIG_AEABI' is

This causes the compiler to add padding in virtchnl2_ptype

In commit ac5047671758 ("hv_netvsc: Disable NAPI before closing the
VMBus channel"), napi_disable was getting called for all channels,
including all subchannels without confirming if they are enabled or not.
This caused hv_netvsc getting hung at napi_disable, when netvsc_probe()
has finished running but nvdev->subchan_work has not started yet.
netvsc_subchan_work() -> rndis_set_subchannel() has not created the
sub-channels and because of that netvsc_sc_open() is not running.
netvsc_remove() calls cancel_work_sync(&nvdev->subchan_work), for which
netvsc_subchan_work did not run.
netif_napi_add() sets the bit NAPI_STATE_SCHED because it ensures NAPI
cannot be scheduled. Then netvsc_sc_open() -> napi_enable will clear the
NAPIF_STATE_SCHED bit, so it can be scheduled. napi_disable() does the
opposite.
Now during netvsc_device_remove(), when napi_disable is called for those
subchannels, napi_disable gets stuck on infinite msleep.
This fix addresses this problem by ensuring that napi_disable() is not
getting called for non-enabled NAPI struct.
But netif_napi_del() is still necessary for these non-enabled NAPI struct
for cleanup purpose.

Invoking the make_tx_response() / push_tx_responses() pair with no lock
held would be acceptable only if all such invocations happened from the
same context (NAPI instance or dealloc thread). Since this isn't the
case, and since the interface "spec" also doesn't demand that multicast
operations may only be performed with no in-flight transmits,
MCAST_{ADD,DEL} processing also needs to acquire the response lock
around the invocations.
To prevent similar mistakes going forward, "downgrade" the present
functions to private helpers of just the two remaining ones using them
directly, with no forward declarations anymore. This involves renaming
what so far was make_tx_response(), for the new function of that name
to serve the new (wrapper) purpose.
While there,
- constify the txp parameters,
- correct xenvif_idx_release()'s status parameter's type,
- rename {,_}make_tx_response()'s status parameters for consistency with
xenvif_idx_release()'s.

Commit d7ac8dca938c ("nvme: quiet user passthrough command errors")
disabled error logging for user passthrough commands. This commit
adds the ability to opt-in to passthrough admin error logging. IO
commands initiated as passthrough will always be logged.
The logging output for passthrough commands (Admin and IO) has been
changed to include CDWXX fields.
nvme0n1: Read(0x2), LBA Out of Range (sct 0x0 / sc 0x80) DNR cdw10=0x0 cdw11=0x1
cdw12=0x70000 cdw13=0x0 cdw14=0x0 cdw15=0x0
Add a helper function nvme_log_err_passthru() which allows us to log
error for passthru commands by decoding cdw10-cdw15 values of nvme
command.
Add a new sysfs attr passthru_err_log_enabled that allows user to conditionally
enable passthrough command logging for either passthrough Admin commands sent to
the controller or passthrough IO commands sent to a namespace.
By default, passthrough error logging is disabled.
To enable passthrough admin error logging:
echo 1 > /sys/class/nvme/nvme0/passthru_err_log_enabled
To disable passthrough admin error logging:
echo 0 > /sys/class/nvme/nvme0/passthru_err_log_enabled

The hostport data structure is shared between the association, this why
we keep track of the users via a refcount. So we should not decrement
the refcount on a match and free the hostport several times.

When the target executes a disconnect and the host triggers a reconnect
immediately, the reconnect command still finds an existing association.
The reconnect crashes later on because nvmet_fc_delete_target_assoc
blindly removes resources while the reconnect code wants to use it.
To address this, nvmet_fc_find_target_assoc should not be able to
lookup an association which is being removed. The association list
is already under RCU lifetime management, so let's properly use it
and remove the association from the list and wait for a grace period
before cleaning up all. This means we also can drop the RCU management
on the queues, because this is now handled via the association itself.
A second step split the execution context so that the initial disconnect
command can complete without running the reconnect code in the same
context. As usual, this is done by deferring the ->done to a workqueue.

The module exit path has race between deleting all controllers and
freeing 'left over IDs'. To prevent double free a synchronization
between nvme_delete_ctrl and ida_destroy has been added by the initial
commit.
There is some logic around trying to prevent from hanging forever in
wait_for_completion, though it does not handling all cases. E.g.
blktests is able to reproduce the situation where the module unload
hangs forever.
If we completely rely on the cleanup code executed from the
nvme_delete_ctrl path, all IDs will be freed eventually. This makes
calling ida_destroy unnecessary. We only have to ensure that all
nvme_delete_ctrl code has been executed before we leave
nvme_fc_exit_module. This is done by flushing the nvme_delete_wq
workqueue.
While at it, remove the unused nvme_fc_wq workqueue too.

XDP queues are created/destroyed when a XDP program

Previously with tegra-smmu, even with CONFIG_IOMMU_DMA, the default domain
could have been left as NULL. The NULL domain is specially recognized by
host1x_client_iommu_attach() as meaning it is not the DMA domain and
should be replaced with the special shared domain.
This happened prior to the below commit because tegra-smmu was using the
NULL domain to mean IDENTITY.
Now that the domain is properly labled the test in DRM doesn't see NULL.
Check for IDENTITY as well to enable the special domains.

The ops->default_domain flow used a 0 req_type to select the default
domain and this was enforced by iommu_group_alloc_default_domain().
When !CONFIG_IOMMU_DMA started forcing the old ARM32 drivers into IDENTITY
it also overroad the 0 req_type of the ops->default_domain drivers to
IDENTITY which ends up causing failures during device probe.
Make iommu_group_alloc_default_domain() accept a req_type that matches the
ops->default_domain and have iommu_group_alloc_default_domain() generate a
req_type that matches the default_domain.
This way the req_type always describes what kind of domain should be
attached and ops->default_domain overrides all other mechanisms to choose
the default domain.

It appears that Sony DVMC-DA1 has a quirk that the descriptor leaf entry
locates just after the vendor directory entry in root directory. This is
not conformant to the legacy layout of configuration ROM described in
Configuration ROM for AV/C Devices 1.0 (1394 Trading Association, Dec 2000,
TA Document 1999027).
This commit changes current implementation to parse configuration ROM for
device attributes so that the descriptor leaf entry can be detected for
the vendor name.

The construct allocating only parts of the vma structure when
the userptr part is not needed is very fragile. A developer could
add additional fields below the userptr part, and the code could
easily attempt to access the userptr part even if its not persent.
So introduce xe_userptr_vma which subclasses struct xe_vma the
proper way, and accordingly modify a couple of interfaces.
This should also help if adding userptr helpers to drm_gpuvm.
v2:
- Fix documentation of to_userptr_vma() (Matthew Brost)
- Fix allocation and freeing of vmas to clearer distinguish
between the types.
