Hi, Currently loading bad PSW flags does not lead to an exception, which is not correct. This series fixes this by implementing what PoP calls "Early Exception Recognition". Since it applies to both loading PSW with LPSW/LPSWE and to interrupt handling, s390_cpu_set_psw() looks like the right place for it to be in.
Patch 1 fixes the issue, patch 2 adds a test.
