From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>
Add the rest of the CRC library functions to kernel-api.
- try to clarify crc32() by adding '@' to a function parameter
- reorder kernel-api CRC functions to be less random
- add more CRC functions to kernel-api
- correct the function parameter names in several places
