Darrick J. Wong	033c338490	libext2fs: optimize the CRC32c implementation ... 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. Signed-off-by: Darrick J.

Darrick J. Wong	db8bbf27c9	libext2fs: Add crc32c implementation for metadata checksumming ... Add a slicing-by-8 CRC32c implementation for metadata checksumming. Adapted from Bob Pearson's kernel patch. Also added a self-test mechanism so we can verify that the crc32c implementation is working correctly. Signed-off-by: Darrick J.
