3  * Hardware-accelerated CRC-32 variants for Linux on z Systems
6  * computing of CRC-32 checksums.
8  * This CRC-32 implementation algorithm processes the most-significant
19 /* Vector register range containing CRC-32 constants */
28  * The CRC-32 constant block contains reduction constants to fold and
31  * For the CRC-32 variants, the constants are precomputed according to
52  * CRC-32 (IEEE 802.3 Ethernet, ...) polynomials:
68  * crc32_be_vgfm_16 - Compute CRC-32 (BE variant) with vector registers
69  * @crc: Initial CRC value, typically ~0.
75  *	V0:	Initial CRC value and intermediate constants and results.
76  *	V1..V4:	Data for CRC computation.
78  *	V9..V14: CRC-32 constants.
