Not sure whether this is really required (I mean select CRC32). The docs
say:
------------------
config CRC32
        tristate "CRC32 functions"
        default y
        select BITREVERSE
        help
          This option is provided for the case where no in-kernel-tree
          modules require CRC32 functions, but a module built outside the
          kernel tree does. Such modules that use library CRC32 functions
------------------

Obviously, hibernation is in the kernel, so maybe we don't need this
after all.

If you know for sure, feel free to point it out.
