This series continues the arch atomic rework started with the smp_mb__ interface cleanup. In this series we (mostly) reduce the atomic implementations by eliminating repetition through use of CPP macros. A future series will use these macros to implement more atomic ops. With these macros we can end up with more atomic ops while the total LoC still shrinks. Furthermore, rewrite the asm-generic/atomic implementations to require less and provide more. This series is compile tested on a number of archs, but only boot tested on x86_64. XXX: someone should try and unify all the hash locked atomic implementations, there's about 4 of them in the tree. --- arch/alpha/include/asm/atomic.h | 225 ++++-------- arch/arc/include/asm/atomic.h | 194 +++------- arch/arm/include/asm/atomic.h | 313 ++++++----------- arch/arm64/include/asm/atomic.h | 213 ++++------- arch/avr32/include/asm/atomic.h | 96 ++--- arch/cris/include/arch-v10/arch/system.h | 2 arch/cris/include/asm/atomic.h | 57 +-- arch/hexagon/include/asm/atomic.h | 68 ++- arch/ia64/include/asm/atomic.h | 182 ++++----- arch/m32r/include/asm/atomic.h | 151 +++----- arch/m68k/include/asm/atomic.h | 119 +++--- arch/metag/include/asm/atomic_lnkget.h | 121 ++---- arch/metag/include/asm/atomic_lock1.h | 76 +--- arch/mips/include/asm/atomic.h | 565 ++++++++++--------------------- arch/mn10300/include/asm/atomic.h | 129 ++----- arch/parisc/include/asm/atomic.h | 121 ++++-- arch/powerpc/include/asm/atomic.h | 216 ++++------- arch/sh/include/asm/atomic-grb.h | 121 ++---- arch/sh/include/asm/atomic-irq.h | 62 +-- arch/sh/include/asm/atomic-llsc.h | 101 ++--- arch/sparc/include/asm/atomic_32.h | 19 - arch/sparc/include/asm/atomic_64.h | 49 +- arch/sparc/include/asm/barrier_32.h | 1 arch/sparc/include/asm/processor.h | 2 arch/sparc/kernel/smp_64.c | 2 arch/sparc/lib/atomic32.c | 25 - arch/sparc/lib/atomic_64.S | 175 ++++----- arch/sparc/lib/ksyms.c | 25 - arch/x86/include/asm/atomic.h | 15 arch/xtensa/include/asm/atomic.h | 231 ++++-------- include/asm-generic/atomic.h | 174 ++++----- include/asm-generic/atomic64.h | 20 - lib/atomic64.c | 83 +--- 33 files changed, 1609 insertions(+), 2344 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
