From 916e97834e023f89b31f796b53cc9c7956e7fe17 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Sat, 15 Aug 2009 11:38:05 +0900 Subject: [PATCH] sh: Kill off unused flush_icache_user_range(). We use flush_cache_page() outright in copy_to_user_page(), and nothing else needs it, so just kill it off. SH-5 still defines its own version, but that too will go away in the same fashion once it converts over.
