[changbin.du at intel.com]

From: Changbin Du <changbin.du at intel.com>

This series of optimization can save about 2MB memory, speed up guest
boot time by ~500ms, lower the hash talbe conflict from 140+ to ones
digit.

v3: Rebase to last stagine brach, fixed a simple conflict of patch #4.
v2: Code improvments, fix comments string.

Changbin Du (6):
  drm/i915/gvt: Optimize MMIO register handling for some large MMIO
    blocks
  drm/i915/gvt: Cleanup struct intel_gvt_mmio_info
  drm/i915/gvt: Make mmio_attribute as type u8 to save 1.5MB memory
  drm/i915/gvt: Make the MMIO attribute wrappers be inline
  drm/i915/gvt: Add helper for tuning MMIO hash table
  drm/i915/gvt: Tuning the size of MMIO hash lookup table to 2048
