bitops: merge little and big endian definisions in asm-generic/bitops/le.h
This patch series introduces little-endian bit operations in asm/bitops.h for all architectures and converts all ext2 non-atomic and minix bit operations to use little-endian bit operations. It enables us to remove ext2 non-atomic and minix bit operations from asm/bitops.h. The reason they should be removed from asm/bitops.h is as follows: For ext2 non-atomic bit operations, they are used for little-endian byte order bitmap access by some filesystems and modules. But using ext2_*() functions on a module other than ext2 filesystem makes some feel strange. For minix bit operations, they are only used by minix filesystem and are useless by other modules. Because byte order of inode and block bitmap is This patch: In order to make the forthcoming changes smaller, this merges macro definisions in asm-generic/bitops/le.h for big-endian and little-endian as much as possible. This also removes unused BITOP_WORD macro.
