From 3bc28c8edc4f5f78d9ec23fb0f20df29b7b3a072 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 18 Jan 2011 13:30:33 +0000 Subject: [PATCH] ARM: v6k: DMA_CACHE_RWFO isn't appropriate for non-v6k CPUs Limit DMA_CACHE_RWFO to only v6k SMP CPUs - V6 CPUs aren't SMP capable, so the read/write for ownership work-around doesn't apply to them.
