[kvm-unit-tests PATCH v2 0/3] better smp interrupt checks

[Claudio Imbrenda <imbrenda@linux.ibm.com>]

Use per-CPU flags and callbacks for Program, Extern, and I/O interrupts
instead of global variables.
    
This allows for more accurate error handling; a CPU waiting for an
interrupt will not have it "stolen" by a different CPU that was not
supposed to wait for one, and now two CPUs can wait for interrupts at
the same time.

Also fix skey.c to be compatible with the new interrupt handling.

Add some utility functions to manipulate bits in the PSW mask, to
improve readability.

  lib: s390x: add functions to set and clear PSW bits
