Subject[PATCH] make do_signal static on i386
Hi Linus,

This patch makes do_signal static in arch/i386/kernel/signal.c which
means its declaration can be removed from asm-i386/signal.h which may
help Jeff out with UML.

I am not sure whether we need the FASTCALL() or whether the change
in the comment in asm-um/signal.h makes sense. (Does UML work on
x86_64, yet?)
