I would just fold all three patches into a single one. It is much easier to review that those selects are done properly when you can see that the define is set for the same architecture.

It is always quite painful to track per arch defines. > Laurent Dufour (3): > mm: introduce ARCH_HAS_PTE_SPECIAL > mm: replace __HAVE_ARCH_PTE_SPECIAL > mm: remove __HAVE_ARCH_PTE_SPECIAL > > Documentation/features/vm/pte_special/arch-support.txt | 2 +- > arch/arc/Kconfig | 1 + > arch/arc/include/asm/pgtable.h | 2 -- > arch/arm/Kconfig | 1 + > arch/arm/include/asm/pgtable-3level.h | 1 - > arch/arm64/Kconfig | 1 + > arch/arm64/include/asm/pgtable.h | 2 -- > arch/powerpc/Kconfig | 1 + > arch/powerpc/include/asm/book3s/64/pgtable.h | 3 --- > arch/powerpc/include/asm/pte-common.h | 3 --- > arch/riscv/Kconfig | 1 + > arch/s390/Kconfig | 1 + > arch/s390/include/asm/pgtable.h | 1 - > arch/sh/Kconfig | 1 + > arch/sh/include/asm/pgtable.h | 2 -- > arch/sparc/Kconfig | 1 + > arch/sparc/include/asm/pgtable_64.h | 3 --- > arch/x86/Kconfig | 1 + > arch/x86/include/asm/pgtable_types.h | 1 - > include/linux/pfn_t.h | 4 ++-- > mm/Kconfig | 3 +++ > mm/gup.c | 4 ++-- > mm/memory.c | 2 +- > 23 files changed, 18 insertions(+), 24 deletions(-) > > -- > 2.7.4 -- Michal Hocko SUSE Labs -- To unsubscribe from this list: send the line "unsubscribe linux-s390" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
