[PATCH] KVM: MMU: Flush guest tlb when reducing permissions on a pte

Browse source

If we reduce permissions on a pte, we must flush the cached copy of the pte
from the guest's tlb.

This is implemented at the moment by flushing the entire guest tlb, and can be
improved by flushing just the relevant virtual address, if it is known.
