[GIT PULL] kmemcheck updates for tip/kmemcheck

[Vegard Nossum <vegard.nossum@gmail.com>]

Hi Ingo,

A rather large update, most of it is implementing the correct REP MOVS/STOS
handling on P4s. I've tested it on both 32-bit and 64-bit and everything
seems good! Also included is the DMA API hooks which prevents false-positive
reports from reads in DMA-able memory.
