[kvm-unit-tests PATCH v1 0/9] s390x: Further extend instruction interception tests

[Nico Boehr <nrb@linux.ibm.com>]

Further extend the instruction interception tests for s390x. This series focuses
on SIGP, STSI and TPROT instructions.

Some instructions such as STSI already had some coverage and the existing tests
were extended to increase coverage.

The SIGP instruction has coverage, but not for all orders. Orders
STORE_ADTL_STATUS, SET_PREFIX and CONDITIONAL_EMERGENCY didn't
have coverage before and new tests are added. For EMERGENCY_SIGNAL, the existing
test is extended to cover an invalid CPU address. Additionally, new tests are
added for quite a few invalid arguments to SIGP.

TPROT was used in skrf tests, but only for storage keys, so add tests for the
other uses as well.

Nico Boehr (9):
  s390x: smp: add tests for several invalid SIGP orders
  s390x: smp: stop already stopped CPU
  s390x: gs: move to new header file
  s390x: smp: add test for SIGP_STORE_ADTL_STATUS order
  s390x: smp: add tests for SET_PREFIX
  s390x: smp: add test for EMERGENCY_SIGNAL with invalid CPU address
  s390x: smp: add tests for CONDITIONAL EMERGENCY
  s390x: add TPROT tests
  s390x: stsi: check zero and ignored bits in r0 and r1
