Subject: [RFC][PATCH 0/5] mm, highmem: kmap_atomic rework -v2
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

Next version of the kmap_atomic rework using Andrew's fancy CPP trickery to
avoid having to convert the whole tree at once.

This is compile tested for i386-allmodconfig, frv, mips-sb1250-swarm,
powerpc-ppc6xx_defconfig, sparc32_defconfig, arm-omap3 (all with
HIGHEM=y).

Boot-tested with: i386-defconfig.

Not tested with:
 - tile, stock toolchain doesn't build tile targets
 - nm10300, the arch doesn't build with highmem to begin with


Is this something we can live with?
