[PATCH 0/2] Properly suspend/resume sub-allocator

[alexdeucher at gmail.com]

From: Alex Deucher <alexander.deucher at amd.com>

This patch set is a bit of a heavy hammer, but I'm
not sure it's worth the effort to create separate
suspend functions for all sub-allocator
users that basically just calls radeon_sa_bo_manager_suspend()
and fix up all the sub allocator init functions to
call radeon_sa_bo_manager_start() since all we are really
avoiding is the allocation of sub-allocator bo.  Additionally
in the VM case, we have to tear down all the VMs on suspend
since the physical addresses of various buffers may have changed
on resume.

The first patch fixes suspend and resume on cards with VM in use.

The second patches doesn't fix any bugs that I know of, but
the current code seems wrong to me unless I'm missing something.

  drm/radeon: fix S/R on VM systems (cayman/TN/SI)
  drm/radeon: tear down the IB pool on suspend
