From f49596a4cf4753d13951608f24f939a59fdcc653 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Tue, 20 Aug 2013 19:53:10 -0500 Subject: [PATCH] powerpc/85xx: Remove -Wa,-me500 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.
