#     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.
