| |
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 v3: - change to the post-fix notation e.g. s/test_le_bit/test_bit_le/
The whole series is available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/mita/linux-2.6.git le-bitops-v4
