From 9959cd88679a227b44195a3db93bd4540899b2fb Mon Sep 17 00:00:00 2001
From: Tim Blechmann <tim@klingt.org>
Date: Mon, 30 Aug 2010 12:20:19 +0200
Subject: [PATCH] perf: Provide kmap_atomic_direct for !CONFIG_HIGHMEM
commit 327735e61bcee29f59a6fd053db894cdddff987e in tip.
ddeca6231cbdebd0fa0f1bac816f1e1e6eae485b doesn't compile, if CONFIG_HIGHMEM
is not enabled, because kmap_atomic_direct and kunmap_atomic_direct are
undefined.
