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

This seems unrelated.

It is, thanks for catching that.
