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.
