| 2007-10-19 | define first set of BIT* macros | Jiri Slaby | |
| define first set of BIT* macros - move BITOP_MASK and BITOP_WORD from asm-generic/bitops/atomic.h to include/linux/bitops.h and rename it to BIT_MASK and BIT_WORD - move BITS_TO_LONGS and BITS_PER_BYTE to bitops.h too and allow easily define another BITS_TO_something (e.g. in event.c) by BITS_TO_TYPE macro Remaining (and common) BIT macro will be defined after all occurences and conflicts will be sorted out in the patches.

| 2006-03-26 | [PATCH] bitops: generic __{,test_and_}{set,clear,change}_bit() and test_bit() | Akinobu Mita | |
| This patch introduces the C-language equivalents of the functions below: void __set_bit(int nr, volatile unsigned long *addr); void __clear_bit(int nr, volatile unsigned long *addr); void __change_bit(int nr, volatile unsigned long *addr); int __test_and_set_bit(int nr, volatile unsigned long *addr); int __test_and_clear_bit(int nr, volatile unsigned long *addr); int __test_and_change_bit(int nr, volatile unsigned long *addr); int test_bit(int nr, const volatile unsigned long *addr); In include/asm-generic/bitops/non-atomic.h This code largely copied from: asm-powerpc/bitops.h Signed-off-by: Akinobu Mita <mita@miraclelinux.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> | |||
