[Intel-gfx] [PATCH 00/11] aliasing ppgtt support v2

[Daniel Vetter]

Hi all,

Changes since the last submission:
- fixed issues pointed out by Chris Wilson on irc.
- fixed an oops on pre-snb, shame on me for that one.
- added two new patches to only bind objects to the global gtt when required.
- added a new patch so that userspace can find out whether ppgtt is on. This is
  required to use MI_STORE/LOAD commands correctly from userspace batchbuffers.
  Luckily no currently released userspace code depends on this, it's just prep
  work.

Comments, test reports, reviews and flames highly welcome.

Yours, Daniel
