mbuesch@freenet.de e5a5b54ab6 [PATCH] fix asmlinkage 
This patch fixes the reintroduced bug with the
sig_handler(), if we link against a -mregparm=3 compiled
klibc on i386.
It also fixes some compiler warnings about redefined
asmlinkage on some systems.
Also some (broken?) compilers on distros throw out warnings
if asmlinkage is before "static void". This fixes it, too.
