For 64-bit book3s the default should be 64K as that's what modern CPUs
are designed for.
The following defconfigs already set CONFIG_PPC_64K_PAGES:
cell_defconfig
pasemi_defconfig
powernv_defconfig
ppc64_defconfig
pseries_defconfig
skiroot_defconfig
The have the option removed from the defconfig, as it is now the
default.
The defconfigs that now need to set CONFIG_PPC_4K_PAGES to maintain
their existing behaviour are:
g5_defconfig
maple_defconfig
microwatt_defconfig
ps3_defconfig
