    [PATCH] __crc_... is intended to be absolute
    i386 boot/compressed/relocs checks for absolute symbols and warns about
    unexpected ones.  If you build with modversions, you get ~2500 warnings
    about __crc_<symbol>.  These suckers are really absolute symbols - we
    do _not_ want to modify them on relocation.
    They are generated by genksyms - EXPORT_... generates a weak alias, then
    genksyms produces an ld script with __crc_<symbol> = <checksum> and it's
    fed to ld to produce the final object file.  Their only use is to match
    kernel and module at modprobe time; they _must_ be absolute.
    boot/compressed/relocs has a whitelist of known absolute symbols, but
    it doesn't know about __crc_... stuff.  As the result, we get shitloads
    of false positives on any ld(1) version.
