Commit 33729a5fc0ca ("iommu/io-pgtable-arm: Remove split on unmap

In the case of Panthor, that means an attempt to run a VM_BIND unmap
operation on a memory region whose start address and size aren't 2MiB
aligned, in the event it intersects with a huge page, would lead to ARM
IOMMU management code to fail and a warning being raised.
Presently, and for lack of a better alternative, it's best to have
Panthor handle partial unmaps at the driver level, by unmapping entire
huge pages and remapping the difference between them and the requested
unmap region.
This could change in the future when the VM_BIND uAPI is expanded to
enforce huge page alignment and map/unmap operational constraints that
render this code unnecessary.
When a partial unmap for a huge PTE is attempted, we also need to expand
the locked region to encompass whole huge pages.

drm/sched: Add several job helpers to avoid drivers touching scheduler state
In the past, drivers used to reach into scheduler internals—this must
end because it makes it difficult to change scheduler internals, as
driver-side code must also be updated.
Add helpers to check if the scheduler is stopped and to query a job’s
signaled state to avoid reaching into scheduler internals. These are
expected to be used driver-side in recovery and debug flows.
Brown paper bag time. This is a silly oversight where I missed to drop
the error condition checking to ensure we clean up on early error
returns. I have an internal unit testset coming up for this which will
catch all such issues going forward.

accel/amdxdna: Fix race where send ring appears full due to delayed head update
The firmware sends a response and interrupts the driver before advancing
the mailbox send ring head pointer. As a result, the driver may observe
the response and attempt to send a new request before the firmware has
updated the head pointer. In this window, the send ring still appears
full, causing the driver to incorrectly fail the send operation.
This race can be triggered more easily in a multithreaded environment,
leading to unexpected and spurious "send ring full" failures.
To address this, poll the send ring head pointer for up to 100us before
returning a full-ring condition. This allows the firmware time to update
the head pointer.
