Darrick J. Wong - March 7, 2012, 12:03 a.m.
The crc32c implementation in the kernel has been refactored a bit to reduce the
amount of code that needs to be maintained, and to speed up tune2fs/e2fsck on
PowerPC by 5-10%.  Port the crc32c changes over, and provide a crc32_be so that
we can remove the duplicate functionality from e2fsck.  Also drop crc32c_be and
crc32_le since neither got used.
