[PATCH 0/5] drm/msm+iommu/arm-smmu-qcom: tlbinv optimizations

[Rob Clark]

From: Rob Clark <robdclark at chromium.org>

Two additions to adreno_smmu_priv to allow for a couple of
optimizations:

 + Use a separate ASID for each set of pgtables to avoid
   over-invalidation.
 + Detect the case of unmapping from non-current pgtables
   where we can skip the redundant tlbinv

Rob Clark (5):
  iommu/arm-smmu-qcom: Fix indentation
  iommu/arm-smmu-qcom: Provide way to access current TTBR0
  iommu/arm-smmu-qcom: Add private interface to tlbinv by ASID
  drm/msm: Use separate ASID for each set of pgtables
  drm/msm: Skip tlbinv on unmap from non-current pgtables
