Subject: fsl_rio.c build problem

Hi,
I'm using:
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
and building for ARCH=powerpc - mpc85xx_defconfig
arch/powerpc/sysdev/fsl_rio.c will not build due to a missing
MCSR_MASK bitmask definition.
The attached patch is based on code found in
git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc.git
and - at the least - will fix the build problem.
BR,
Kerstin
