Cover letter [kvm-unit-tests PATCH v2 0/2] s390x: program interrupt handler
Add a program interrupt handler and two simple program interrupt tests.
The check for the ADRESSING exception will fail on
- TCG without "target/s390x: addressing exceptions are suppressing"
- Old KVM versions without 492d8642eaef ("KVM: s390: Forward PSW to next instruction for addressing exceptions")
v1 -> v2: (s390x: generate asm offsets for the lowcore)
- Added missing field (mcck extended save area)
- Dropped alignment attribute for naturally aligned struct
v1 -> v2: (pgm interrupt handler and a way to test them)
- Renamed everything from irq->int/interrupt to keep it consistent
- Use global lowcore variable struct lowcore *lc;
- Safe+restore fpr and fpc in interrupt handler
- Setup pgm int handler using mvc instruction
- Renamed received_pgm_irq to check_pgm_int_code() and moved "report" into "check_pgm_int_code()"
- Minor style + comment fixes
