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.
