Message-Id: <20070517101143.3113.60295.sendpatchset@skynet.skynet.ie>

Subject: [PATCH 4/5] Rename GFP_HIGH_MOVABLE to GFP_HIGHUSER_MOVABLE
__GFP_HIGH are used to flag allocations that can access emergency
pools. GFP_HIGH_MOVABLE has little to do with __GFP_HIGH and the name is
misleading. This patch renames GFP_HIGH_MOVABLE to GFP_HIGHUSER_MOVABLE so
that it is clearer.
