[Intel-gfx] [RFCv3 0/3] Introduce private PAT management

[Zhi Wang]

This patchset introduces private PPAT managment which enables dynamically
configuring PPAT at runtime. The previous static PPAT configuration is
kept unchanged.

v3:
- Remove intel_ppat_reserved. (Chris)

v2:

sits in i915.

Zhi Wang (3):
  drm/i915: Factor out setup_private_pat()
  drm/i915: Introduce private PAT management
  drm/i915: Introduce per-platform PPAT configurations
