Sure,

[ 0.543862] crc32: CRC_LE_BITS = 64, CRC_BE BITS = 64
[ 0.543864] crc32: self tests passed, processed 225944 bytes in 118678 nsec
[ 0.543986] crc32c: CRC_LE_BITS = 64
[ 0.543987] crc32c: self tests passed, processed 112972 bytes in 58932 nsec
[ 0.569479] crc32_combine: 8373 self tests passed
[ 0.595330] crc32c_combine: 8373 self tests passed

it does the trick. Thanks!
