Description

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu/userq: pin mqd and fw object bo to avoid eviction

mqd and fw objects are queue core objects which should remain
valid and never be unmapped and evicted for user queues to work
properly.

During eviction if these buffers are evicted the hw continue to
use the invalid addresses and caused page faults and system hung.
