Subject[PATCH] Consolidate signal numbers
Hi Linus,

I noticed that 13 of our architectures share the same set of signal
numbers (and um doesn't really count) so this patch creates
asm-generic/signum.h containing that set (it happens to be the set used by
i386). I also created asm-*/signum.h so that it is clearer (I think) what
the idea is for future architectures.

Here is the generic and i386 parts of the patch. Does this look worth
while doing, and do you want the rest of the patch? The diffstat for the
whole thing looks like this:

I intend to try to consolidate some more of the signal code over time,
this is just a small beginning.
