After write-protecting the region, currently KVM invalidates the entire TLB entries using kvm_flush_remote_tlbs(). Instead, scope the invalidation only to the targeted memslot. If supported, the architecture would use the range-based TLBI instructions to flush the memslot or else fallback to flushing all of the TLBs.
