From f9e2bdfdbb4c9da13422b349227be8c7b41dbd44 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 9 Sep 2009 17:14:19 +0900 Subject: sh: Factor in cpu id for selection of cache colour fixmap. In the SMP VIPT case the page copy/clear ops still perform colouring, care needs to be taken that CPUs don't end up stepping on each other, so we give them a bit of room to work with. At the same time, we reduce the worst-case colouring given that these pages are always consumed.
