Andrew, please consider to include this patch series into -mm.

Changelog:

 * v3
 - add Acked-by: lines

 * v2
(cover letter for v2 was not delivered to any mailing lists I've CCed may be
due to Too many recipients to the message)
 - fix argument of test_and_{set,clear}_le_bit() for s390, arm, m68k
 - move ext2 bitops to fs/ext2/ext2.h, not include/linux/ext2_fs.h
 - fix m68k minix bitops incorrect conversion noticed by Andreas Schwab
 - rewrite minix bitops removal patch based on the suggestion by Arnd

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 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 someone feel strange.

For minix bit operations, they are only used by minix filesystem and useless
by other modules. Because byte order of inode and block bitmap is defferent
on each architecture.

Akinobu Mita (22):

  bitops: introduce little-endian bitops for most architectures
  rds: stop including asm-generic/bitops/le.h
  kvm: stop including asm-generic/bitops/le.h
  asm-generic: use little-endian bitops
