3  * cleaned up code to current version of sparse and added the slicing-by-8
4  * algorithm to the closely similar existing slicing-by-4 algorithm.
9  * subsequently included in the kernel, thus was re-licensed under the
10  * GNU GPL v2.
16  * Some xor at the end with ~0.  The generic crc32() function takes
17  * seed as an argument, and doesn't xor at the end.  Then individual
19  *   drivers/net/smc9194.c uses seed ~0, doesn't xor with ~0.
20  *   fs/jffs2 uses seed 0, doesn't xor with ~0.
21  *   fs/partitions/efi.c uses seed ~0, xor's with ~0.
