[PATCH 2/4] powerpc/85xx: Remove -Wa,-me500
From: Scott Wood <hidden>
Date: 2013-08-21 02:13:40
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:

This caused lwsync to be converted to sync on 64-bit (on 32-bit lwsync is generated at runtime, and so wasn't affected). Not using lwsync caused a significant slowdown on certain workloads. Setting this flag for any e500-enabled build is also not friendly to multiplatform kernels. Signed-off-by: Scott Wood <redacted> --- arch/powerpc/Makefile | 1 - 1 file changed, 1 deletion(-)
