From mboxrd@z Thu Jan 1 00:00:00 1970 From: Akinobu Mita Subject: [PATCH v2 0/6] remove CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT} Date: Tue, 26 Apr 2011 22:23:37 +0900 Message-ID: <1303824223-3566-1-git-send-email-akinobu.mita@gmail.com> Return-path: Received: from mail-pz0-f46.google.com ([209.85.210.46]:55095 "EHLO mail-pz0-f46.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752848Ab1DZNXu (ORCPT ); Tue, 26 Apr 2011 09:23:50 -0400 Sender: linux-arch-owner@vger.kernel.org List-ID: To: linux-kernel@vger.kernel.org, linux-arch@vger.kernel.org, akpm@linux-foundation.org, arnd@arndb.de Cc: Akinobu Mita Changelog v2: - Add Acked-by: line - Rebase to mainline The style that we normally use in asm-generic is to test the macro itself for existence, so in asm-generic, do: #ifndef find_next_zero_bit_le extern unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset); #endif and in the architectures, write static inline unsigned long find_next_zero_bit_le(const void *addr, unsigned long size, unsigned long offset) #define find_next_zero_bit_le find_next_zero_bit_le But CONFIG_GENERIC_FIND_{NEXT_BIT,BIT_LE,LAST_BIT} options are used to test for existence of find bitops now. 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 due 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
