powerpc/64s: Default to 64K pages for 64 bit book3s
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 Signed-off-by: Joel Stanley <joel@jms.id.au> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> BugLink: https://github.com/linuxppc/issues/issues/109 Link: https://lore.kernel.org/r/20211015001649.45591-1-joel@jms.id.au
