Well, it looks OK, but I'm sure people are going to get confused with
fls vs. fls64 vs. __fls all being subtly different.  I'd say it's
worth putting a little file in the Documentation directory to explain
it all.

I'm not sure why the "add __fls to all 64-bit architectures" change
has to be done as a single patch rather than a patch per architecture
going through the architecture maintainers.  I suppose that avoids any
problem with some maintainers not sending it upstream quickly.  I
would expect that if it is a single cross-architecture patch that it
would go through Andrew Morton, though.  But if Andrew wants you to
handle it then I'm happy to give you an Acked-by for it.
