Cross testing emulated instructions has in the past brought up some
issues on all available IBM Z hypervisors. So let's upstream the last
part of multiboot: sclp interrupts and line mode console.

SMP tests are a great way to excercise external interruptions, cpu
resets and sigp. The smp library is always initialized and provides
very rudimentary CPU management for now.

v3:
* Simplified linemode buffering
* Removed error constant use
* Smaller fixes

Janosch Frank (6):
s390x: Use interrupts in SCLP and add locking
s390x: Add linemode console
s390x: Add linemode buffer to fix newline on every print
s390x: Add initial smp code
s390x: Prepare for external calls
s390x: SMP test
