From 7fbb2d3bdd33e58f54e360df0723d754f0b66153 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Sat, 15 Aug 2009 11:25:32 +0900 Subject: [PATCH] sh: consolidate flush_dcache_mmap_lock/unlock() definitions. All of the flush_dcache_mmap_lock()/flush_dcache_mmap_unlock() definitions are identical across all CPUs, so just provide them generically in asm/cacheflush.h.
