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
