powerpc/mm: Allow ARCH_FORCE_MAX_ORDER up to 12
Christophe reported that the change to ARCH_FORCE_MAX_ORDER to limit the
range to 10 had broken his ability to configure hugepages:
# echo 1 > /sys/kernel/mm/hugepages/hugepages-8192kB/nr_hugepages
sh: write error: Invalid argument
Several of the powerpc defconfigs previously set the
ARCH_FORCE_MAX_ORDER value to 12, via the definition in
arch/powerpc/configs/fsl-emb-nonhw.config, used by:
mpc85xx_defconfig
mpc85xx_smp_defconfig
corenet32_smp_defconfig
corenet64_smp_defconfig
mpc86xx_defconfig
mpc86xx_smp_defconfig
Fix it by increasing the allowed range to 12 to restore the previous
behaviour.
