powerpc/8xx: dont save CR in SCRATCH registers CR only needs to be preserved when checking if we are handling a kernel address. So we can preserve CR in a register: - In ITLBMiss, check is done only when CONFIG_MODULES is defined. Otherwise we don't need to do anything at all with CR. - We use r10, then we reload SRR0/MD_EPN into r10 when CR is restored Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Scott Wood <scottwood@freescale.com>
