[PATCH 52/83] hsa/radeon: Add process queue manager module
From: Ben Goz
The queue scheduler divides into two sections, one section is process bounded
and the other section is device bounded.
The process bounded section is handled by this module. The PQM handles HSA
queue setup, updates and tear-down.
