* kvm-arm64/mmu-misc-6.12:
  : .
  : Various minor MMU improvements and bug-fixes:
  :
  : - Prevent MTE tags being restored by userspace if we are actively
  :   logging writes, as that's a recipe for disaster
  :
  : - Correct the refcount on a page that is not considered for MTE
  :   tag copying (such as a device)
  :
  : - When walking a page table to split blocks, keep the DSB at the end
  :   the walk, as there is no need to perform it on every store.
  :
  : - Fix boundary check when transfering memory using FFA
  : .
  KVM: arm64: Add memory length checks and remove inline in do_ffa_mem_xfer
  KVM: arm64: Disallow copying MTE to guest memory while KVM is dirty logging
  KVM: arm64: Release pfn, i.e. put page, if copying MTE tags hits ZONE_DEVICE
  KVM: arm64: Move data barrier to end of split walk
