Hi,

This is a follow-up series for [1].

The fix has been committed.

I asked Christian what might be a good alternative for the
mmio-debug-exit device for testing, and he suggested to look into
shutdown/panic actions.

Patch 1 adds a new panic action.
Patch 2 tests unaligned stores to s390x low-address-protected lowcore;
it performs a shutdown on success and panic on failure.

Best regards,
Ilya

v2: https://lists.gnu.org/archive/html/qemu-devel/2022-07/msg04129.html
v2 -> v3: Add @since tag (Eric).
          Fix a small style issue in the test.
