amd_powerplay_destroy() expects a handle pointing to a struct pp_instance.
On chips without PowerPlay, pp_handle points to a struct amdgpu_device. The
resulting attempt to kfree() fields of the wrong struct ends in fire:

These patches fix problems that occur when attempting to unload the amdgpu
module on my R9 290. It now unloads without any (obvious) errors.
Unfortunately, however, I hit a snag when trying to load the module again after
unloading it:

We unref the man->move fence in ttm_bo_clean_mm() and then call
ttm_bo_force_list_clean() which waits on it, except the refcount is now
zero so a warning is generated (or worse):

[149492.279309] [ cut here ]

For userspace BO allocations, replace AMDGPU_GEM_CREATE_CPU_ACCESS_REQUIRED
with a new AMDGPU_BO_FLAG_CPU_ACCESS flag. This flag will be used to
indicate that a BO should currently be CPU accessible. Unlike the
CPU_ACCESS_REQUIRED flag, it is meant to be an ephemeral rather than a
permanent constra

drm_prop_enum_lists are not supposed to change at runtime. All functions
working with drm_prop_enum_list provided by work with
const drm_prop_enum_list. So mark the non-const structs as const.

This allows us to write the mapped PTEs into
an IB instead of the table directly.
