From 6dbd972850c092e50e10bd14a3324e2abe88997a Mon Sep 17 00:00:00 2001 From: Deng-Cheng Zhu Date: Tue, 12 Oct 2010 19:37:20 +0800 Subject: [PATCH] MIPS: define local_xchg from xchg_local to atomic_long_xchg Perf-events is now using local_t helper functions internally. There is a use of local_xchg(). On MIPS, this is defined to xchg_local() which is missing in asm/system.h. This patch re-defines local_xchg() in asm/local.h to atomic_long_xchg(). Then Perf-events can pass the build.
