[PATCH v2 0/3] Better handle memory pressure at suspend

[Mario Limonciello]

At suspend time if there is memory pressure then dynamically allocating
memory will cause failures that don't clean up properly when trying
suspend a second time.

Move the bigger memory allocations into Linux PM prepare() callback and
drop allocations that aren't really needed in DC code.

v1: https://patchwork.freedesktop.org/patch/559270/
v1->v2:
 * Handle DC code too
 * Add prepare callback rather than moving symbol calls

Mario Limonciello (3):
  drm/amd: Add support for prepare() callback
  drm/amd: Move evict resources suspend step to prepare()
  drm/amd/display: Destroy DC context while keeping DML
