Marc Zyngier 98db7259fa KVM: arm64: Set the MTE tag bit before releasing the page 
Setting a page flag without holding a reference to the page
is living dangerously. In the tag-writing path, we drop the
reference to the page by calling kvm_release_pfn_dirty(),
and only then set the PG_mte_tagged bit.

It would be safer to do it the other way round.
