[v2,00/10] s390x: smp: Improve smp code part 2

Message

Let's continue cleaning up the smp test and smp related functions.

We add:
   * Test for external/emergency calls after reset
   * Test SIGP restart while running
   * SIGP stop and store status while running
   * CR testing on reset

We fix:
   * Proper check for sigp completion
   * smp_cpu_setup_state() loop and return address in r14


GIT: https://github.com/frankjaa/kvm-unit-tests/tree/smp_cleanup2

v2:
	* Added some rev-bys and acks
	* Explicitly stop and start cpu before hot restart test
