Yeah, I just threw it out as a trial balloon without thinking about it
properly.  We need to test:

include/asm-alpha/types.h:#include <asm-generic/int-l64.h>
include/asm-ia64/types.h:#include <asm-generic/int-l64.h>
include/asm-mips/types.h:# include <asm-generic/int-l64.h>
include/asm-powerpc/types.h:# include <asm-generic/int-l64.h>
include/asm-s390/types.h:# include <asm-generic/int-l64.h>
include/asm-sparc/types.h:#include <asm-generic/int-l64.h>

I can take care of ia64 easily enough.  Ben is, I presume, willing to
take care of powerpc.  Just need to find suckers^W people willing to fix
up alpha, mips, s390 and sparc.

I don't think this needs to go in during the merge window, I'm happy to
wait until -rc2 or something.  Anyway, initial patch at
http://git.kernel.org/?p=linux/kernel/git/willy/misc.git;a=shortlog;h=u64-ull
so if anyone wants to get started early ...
