thanks, looks nice, except for a small detail:

there should be an #else here i think, which maps find_next_bit to 
__find_next_bit / etc.

small syntactic nit:

> +unsigned long __find_next_bit(const unsigned long *addr,
> +		unsigned long size, unsigned long offset);

should be explicitly "extern", so that we see that it's a prototype 
declaration.
