Martin Schwidefsky 51eee033dc s390: add support to start the kernel in 64 bit mode. 
Do the switch to z/Architecture (alias 64 bit) mode early in head.S.
If the machine is already running in 64 bit mode the sigp turns into
a nop. With this change it doesn't matter in which mode the kernel
is started.
