MCSR_MASK is not defined anywhere, so when I compile this code, I get this:

CC arch/powerpc/sysdev/fsl_rio.o
arch/powerpc/sysdev/fsl_rio.c: In function 'fsl_rio_mcheck_exception':
arch/powerpc/sysdev/fsl_rio.c:248: error: 'MCSR_MASK' undeclared
(first use in this function)
arch/powerpc/sysdev/fsl_rio.c:248: error: (Each undeclared identifier
is reported only once
arch/powerpc/sysdev/fsl_rio.c:248: error: for each function it appears in.)
