In addition to the header, we have to do these other small changes: - move the 'extern' declarations out of memset_io/memcpy_io to make them visible to the symbol version generator - move the exports from bitops.h to {change,clear,set,...}bit.S - move the exports from csumpartialgeneric.S into the files including it I couldn't find the correct prototypes for the compiler builtins, so I went with the fake 'void f(void)' prototypes that we had before.
