* 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 Signed-off-by: Oliver Upton <oliver.upton@linux.dev>
