Classic Algorithm (one bit at a time)

configname: CONFIG_CRC32_BIT

CRC32 implementation
└─>Classic Algorithm (one bit at a time)
In linux kernel since version 3.1 (release Date: 2011-10-24)  
Calculate checksum one bit at a time. This is VERY slow, but has
no lookup table. This is provided as a debugging option.

Only choose this option if you are debugging crc32.
