Subject: [PATCH v2 0/2] Fixes for batched TLB flushes

The recent introduction of batched TLB flushes causes accounting problems in
vmstat and misses some tracepoints. In addition, I am afraid it might cause
problems in some platforms (Xen, UV) since it uses non-standard APIs.

v1->v2
* Added second patch to use standard api for invalidations
* cc'ing linux-mm

Nadav Amit (2):
  x86/mm: TLB_REMOTE_SEND_IPI should count pages
  mm/rmap: batched invalidations should use existing api
