3.19.8-ckt4 -stable review patch. If anyone has any objections, please let me know.

From: Paolo Bonzini <pbonzini@redhat.com>
commit 69a1220060c1523fd0515216eaa29e22f133b894 upstream.
The argument to KVM_GET_DIRTY_LOG is a memslot id; it may not match the position in the memslots array, which is sorted by gfn.
