Subject[PATCH v5 21/27] udf: 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.

Change from v4:
- remove casts to "unsigned long *" due to le-bitops prototype change

The whole series is available in the git branch at:
git:// le-bitops-v5
