asm-generic: add another generic ext2 atomic bitops ... The majority of architectures implement ext2 atomic bitops as test_and_{set,clear}_bit() without spinlock. This adds this type of generic implementation in ext2-atomic-setbit.h and use it wherever possible.

asm-generic: use little-endian bitops ... As a preparation for removing ext2 non-atomic bit operations from asm/bitops.h. This converts ext2 non-atomic bit operations to little-endian bit operations.

[PATCH] bitops: generic ext2_{set,clear}_bit_atomic() ... This patch introduces the C-language equivalents of the functions below: int ext2_set_bit_atomic(int nr, volatile unsigned long *addr); int ext2_clear_bit_atomic(int nr, volatile unsigned long *addr); In include/asm-generic/bitops/ext2-atomic.h This code largely copied from: include/asm-sparc/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> Akinobu Mita   authored and   Linus Torvalds   commited 2006-03-26 08:57:11 -08:00	765f34fe32
