    SubjectRe: crc32 cleanups
    That doesn't solve the problem, if your kernel doesn't use the crc
    functions but an externel one (special driver - eventually binary) module
    needs the code. The external driver may give a message like "crc functions
    needed - please recompile your kernel with crc support". Is this ok for
    the normal user ?

    > Just use the existing linker features. Link the crc code as an .a library.
    > If some code needs it it'll get included. If it needs initialization
    > use the existing __initcall() setup. It'll generate a call to the
    > initialization function when it is linked in, and none if it is not.
