This patch series switches find bitops to follow the normal style described above. This change enables arm and s390 to use asm-generic/bitops/le.h header file and fixes m68knommu build error due to the lack of find_next_bit_le(). Akinobu Mita (6): arch: add #define for each of optimized find bitops bitops: add #ifndef for each of find bitops arch: remove CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT} arm: use asm-generic/bitops/le.h s390: use asm-generic/bitops/le.h m68knommu: fix build error dule to the lack of find_next_bit_le() arch/alpha/Kconfig | 4 --- arch/arm/include/asm/bitops.h | 46 ++++++------------------------------ arch/avr32/include/asm/bitops.h | 15 ++++++++++++ arch/blackfin/Kconfig | 3 -- arch/cris/Kconfig | 4 --- arch/frv/Kconfig | 8 ------ arch/h8300/Kconfig | 8 ------ arch/ia64/Kconfig | 4 --- arch/m32r/Kconfig | 8 ------ arch/m68k/Kconfig.nommu | 4 --- arch/m68k/include/asm/bitops_mm.h | 8 ++++++ arch/m68k/include/asm/bitops_no.h | 4 +++ arch/microblaze/Kconfig | 6 ----- arch/mips/Kconfig | 8 ------ arch/mn10300/Kconfig | 3 -- arch/parisc/Kconfig | 8 ------ arch/powerpc/Kconfig | 8 ------ arch/s390/include/asm/bitops.h | 45 ++++++++---------------------------- arch/score/Kconfig | 3 -- arch/sh/Kconfig | 6 ----- arch/sparc/Kconfig | 8 ------ arch/tile/Kconfig | 1 - arch/um/Kconfig.x86 | 1 - arch/x86/Kconfig | 1 - arch/xtensa/Kconfig | 6 ----- include/asm-generic/bitops/find.h | 4 +++ include/asm-generic/bitops/le.h | 7 +++++ include/linux/bitops.h | 4 +- lib/Kconfig | 10 -------- lib/Makefile | 9 ++----- lib/find_last_bit.c | 4 +++ lib/find_next_bit.c | 18 +++++++++----- 32 files changed, 77 insertions(+), 199 deletions(-) -- 1.7.4.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
