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 arch/x86/include/asm/tlbflush.h | 6 ------ arch/x86/mm/tlb.c | 14 ++++++++++---- mm/rmap.c | 28 +++++++--------------------- 3 files changed, 17 insertions(+), 31 deletions(-) -- 2.5.0 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
