Subject[PATCH v5 12/27] bitops: introduce little-endian bitops for most architectures
Date
Introduce little-endian bit operations to the big-endian architectures
which do not have native little-endian bit operations and the little-endian
architectures. (alpha, avr32, blackfin, cris, frv, h8300, ia64, m32r,
mips, mn10300, parisc, sh, sparc, tile, x86, xtensa)

These architectures can just include generic implementation
(asm-generic/bitops/le.h).
