Series applied, thanks.

Although two topics for possibly resolving later:

1) That 1ULL bit mask fix is quite expensive on 32-bit, it would
   probably be cheaper to test for that case using a helper function
   that nops out on 64-bit.  Although this is not so important.

2) That static inline forward declaration is ugly, better to remove
   the inline tag (let the compiler handle it) or move the function
   above all the call sites.
