We just wanted c sourcefiles out of the top level, not c source
directories.

- * Dr. Ross N. Williams has a great document to introduce the idea of CRC

- * crc64table[256] is the lookup table of a table-driven 64-bit CRC
- * calculation, which is generated by gen_crc64table.c in kernel build
- * time. The polynomial of crc64 arithmetic is from ECMA-182 specification
- * as well, which is defined as,
- *
- * x^64 + x^62 + x^57 + x^55 + x^54 + x^53 + x^52 + x^47 + x^46 + x^45 +
