Applied everything else except #8, that might require more thought. Gave it a test under z/VM and TCG. Under z/VM I get: ABORT: smp: cpu reset: Unexpected external call interrupt (code 0x1201): on cpu 1 at 0x110f4 Which - I think - is expected with older kernels (on 5.4.13) that miss the reset of local interrupts via the new kernel interface https://github.com/davidhildenbrand/qemu.git s390-tcg-next Thanks!
