Doing a XE_EXEC with num_batch_buffer == 0 makes signals passed as
argument to be signaled when the last real XE_EXEC is completed.
But to do that it was first pinning all VMAs in drm_gpuvm_exec_lock(),
this patch remove this pinning as it is not required.
This change also help Mesa implementing memory over-commiting recovery
as it needs to unbind not needed VMAs when the whole VM can't fit
in GPU memory but it can only do the unbiding when the last XE_EXEC
is completed.
So with this change Mesa can get the signal it want without getting
out-of-memory errors.

Rather than return an error to the user or ban the VM when userptr VMA
page pin fails with -EFAULT, invalidate VMA mappings. This supports the
UMD use case of freeing userptr while still having bindings.
Now that non-faulting VMs can invalidate VMAs, drop the usm prefix for
the tile_invalidated member.

- Fix build error (CI)
v3:
- Don't invalidate VMA if in fault mode, rather kill VM (Thomas)
- Update commit message with tile_invalidated name chagne (Thomas)
- Wait VM bookkeep slots with VM resv lock (Thomas)
v4:
- Move list_del_init(&userptr.repin_link) after error check (Thomas)
- Assert not in fault mode (Matthew)

None of the callers of drm_panel_get_modes() expect it to return
negative error codes. Either they propagate the return value in their
struct drm_connector_helper_funcs .get_modes() hook (which is also not
supposed to return negative codes), or add it to other counts leading to
bogus values.
On the other hand, many of the struct drm_panel_funcs .get_modes() hooks
do return negative error codes, so handle them gracefully instead of
propagating further.
Return 0 for no modes, whatever the reason.

The hwdb selection logic as a feature that allows it to mark some fields
as 'don't care'. If we match with such a field we memcpy(..)
the current etnaviv_chip_identity into ident.
This step can overwrite some id values read from the GPU with the
'don't care' value.
Fix this issue by restoring the affected values after the memcpy(..).
As this is crucial for user space to know when this feature works as
expected increment the minor version too.

Using the ring_muxer without preemption adds overhead for no
reason since mcbp cannot be triggered.
Moving back to a single queue in this case also helps when
high priority app are used: in this case the gpu_scheduler
priority handling will work as expected - much better than
ring_muxer with its 2 independant schedulers competing for
the same hardware queue.
This change requires moving amdgpu_device_set_mcbp above
amdgpu_device_ip_early_init because we use adev->gfx.mcbp.

First of all calculating the number of dw to patch into a

This is just standard ring buffer calculations. While at it also
reduce the BUG_ON() into WARN_ON().
Then instead of a random bit pattern use 0 as default value for
the number of dw skipped, this way it's not mandatory any more
to patch the conditional execution.
And last make the address to check a parameter of the
