[PATCH] powerpc/pseries: Kill all prefetch streams on context switch

2013-05-29 Thread Michael Neuling
On context switch, we should have no prefetch streams leak from one userspace process to another. This frees up prefetch resources for the next process. Based on patch from Milton Miller. Signed-off-by: Michael Neuling diff --git a/arch/powerpc/include/asm/ppc_asm.h b/arch/powerpc/include/asm
