If you also added

#define for_each_bit(bit, addr, size) for_each_set_bit((bit), (addr), (size))

Then the transition can be made not as painful i.e. less likely to impact
on new users of for_each_bit() that may not currently be in Linus' tree.

(and the patch to bitops.h could be submitted on its own, and the other
parts could be sent to their respective maintainer - which also lowers
the pain for them with conflicts etc).
