[v4,0/2] Splitting intel-gtt calls for non-x86 platforms

Message

The intel-gtt module defines some functions used by i915, but they are
only supported by x86 platforms. In order to bring i915 to a more
arch-neutral state, we split out these functions and provide stubs in
the case of non-x86 builds.

There may be a better filename choice for the files used in splitting
the calls, it's very much open to discussion.

v2: Refactored to move gmch functions, renamed exported functions
v3: Added drm/i915_drm.h header
v4: Rebased on drm-intel-next, resolved build and naming issues

Casey Bowman (2):
  drm/i915/gt: Split intel-gtt functions by arch
  drm/i915: Require INTEL_GTT to depend on X86
