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 Link: https://github.com/linuxppc/issues/issues/109 Signed-off-by: Joel Stanley <joel@jms.id.au> --- arch/powerpc/Kconfig | 1 + arch/powerpc/configs/cell_defconfig | 1 - arch/powerpc/configs/g5_defconfig | 1 + arch/powerpc/configs/maple_defconfig | 1 + arch/powerpc/configs/microwatt_defconfig | 2 +- arch/powerpc/configs/pasemi_defconfig | 1 - arch/powerpc/configs/powernv_defconfig | 1 - arch/powerpc/configs/ppc64_defconfig | 1 - arch/powerpc/configs/ps3_defconfig | 1 + arch/powerpc/configs/pseries_defconfig | 1 - arch/powerpc/configs/skiroot_defconfig | 1 - 11 files changed, 5 insertions(+), 7 deletions(-)
