3  * Normal 64-bit CRC calculation.
9  * Dr. Ross N. Williams has a great document to introduce the idea of CRC
13  * http://www.ross.net/crc/download/crc_v3.txt
15  * crc64table[256] is the lookup table of a table-driven 64-bit CRC
46  * @crc: seed value for computation. 0 or (u64)~0 for a new CRC calculation,
51 u64 __pure crc64_be(u64 crc, const void *p, size_t len)  in crc64_be()  argument
58 		t = ((crc >> 56) ^ (*_p++)) & 0xFF;  in crc64_be()
59 		crc = crc64table[t] ^ (crc << 8);  in crc64_be()
62 	return crc;  in crc64_be()
68  * @crc: seed value for computation. 0 for a new CRC calculation, or the
73 u64 __pure crc64_rocksoft_generic(u64 crc, const void *p, size_t len)  in crc64_rocksoft_generic()  argument
78 	crc = ~crc;  in crc64_rocksoft_generic()
81 		crc = (crc >> 8) ^ crc64rocksofttable[(crc & 0xff) ^ *_p++];  in crc64_rocksoft_generic()
83 	return ~crc;  in crc64_rocksoft_generic()
