Merge branch kvm-arm64/virtual-cache-geometry into kvmarm/next

* kvm-arm64/virtual-cache-geometry:
  : Virtualized cache geometry for KVM guests, courtesy of Akihiko Odaki.
  :
  : KVM/arm64 has always exposed the host cache geometry directly to the
  : guest, even though non-secure software should never perform CMOs by
  : Set/Way. This was slightly wrong, as the cache geometry was derived from
  : the PE on which the vCPU thread was running and not a sanitized value.
  :
  : All together this leads to issues migrating VMs on heterogeneous
  : systems, as the cache geometry saved/restored could be inconsistent.
  :
  : KVM/arm64 now presents 1 level of cache with 1 set and 1 way. The cache
  : geometry is entirely controlled by userspace, such that migrations from
  : older kernels continue to work.
  KVM: arm64: Mark some VM-scoped allocations as __GFP_ACCOUNT
  KVM: arm64: Normalize cache configuration
  KVM: arm64: Mask FEAT_CCIDX
  KVM: arm64: Always set HCR_TID2
  arm64/cache: Move CLIDR macro definitions
  arm64/sysreg: Add CCSIDR2_EL1
  arm64/sysreg: Convert CCSIDR_EL1 to automatic generation
  arm64: Allow the definition of UNKNOWN system register fields
