[PATCH 00/17] Process Isolation Support

[Alex Deucher]

This patch set enables process isolation mode which
serializes access to the graphics block between processes.
When this mode is active, a cleaner shader is run between
processes to clear shader LDS (Local Data Store) and GPRs
(General Purpose Registers).  A sysfs interface is
also available to manually clear LDS and GPRs if you
for example want to clear LDS and GPRs when a user logs out.

This includes support for GFX 9.4.3 and 9.4.4.  Support for
other GPUs is in progress and will be available when ready.
