[PATCH v3 1/2] drm/i915/gtt: grab wakeref in gen6_alloc_va_range

[Matthew Auld]

Some steps in gen6_alloc_va_range require the HW to be awake, so ideally
we should be grabbing the wakeref ourselves and not relying on the
caller already holding it for us.

[PATCH v3 2/2] drm/i915: add in-kernel blitter client

[Matthew Auld]

The plan is to use the blitter engine for async object clearing when
using local memory, but before we can move the worker to get_pages() we
have to first tame some more of our struct_mutex usage. With this in
mind we should be able to upstream the object clearing as some
selftests, which should serve as a guinea pig for the ongoing locking
rework and upcoming asyc get_pages() framework.
