This is due to a pending parport patch, obviously not yet
integrated. NB: The patch has been posted to linux-kernel
some time ago (with overwhelming feedback 8-)) and is also
on Andrew Tridgell's Jitterbug Page...

No, your guess is wrong.

Since there are several modules that need the "hamming weight" (aka
population
count) functionality and several CPU archs have instructions for this
that are faster than the generic C code, my idea was to move these
routines
to arch specific code. This is also in a pending patch, obviously not
yet
integrated.

What I want from Linus is a statement whether the moving of these
routines
to asm/bitops.h (or wherever) is ok or not.
