  : letter:
  :
  : "This small series fixes the granule size selection for software stage-1
  :  and stage-2 walks. Previously we treat the guest's TCR/VTCR.TGx as-is
  :  and use the encoded granule size for the walks. However this is
  :  incorrect if the granule sizes are not advertised in the guest's
  :  ID_AA64MMFR0_EL1.TGRAN*. The architecture specifies that when an
  :  unsupported size is programed in TGx, it must be treated as an
  :  implemented size. Fix this by choosing an available one while
  :  prioritizing PAGE_SIZE."
  : .
  KVM: arm64: Fallback to a supported value for unsupported guest TGx
  KVM: arm64: nv: Use literal granule size in TLBI range calculation
  KVM: arm64: Factor out TG0/1 decoding of VTCR and TCR
  KVM: arm64: nv: Rename vtcr_to_walk_info() to setup_s2_walk()
