If the PER-3 facility is installed, the breaking-event address is to be stored in the low core. There is no facility bit for PER-3 in stfl(e) and Linux always uses the value at address 272 no matter if PER-3 is available or not. We can't hide its existence from the guest. All program interrupts injected via the SIE automatically store this information if the PER-3 facility is available in the hypervisor. Also the itdb contains the address automatically. As there is no switch to turn this mechanism off, let's simply make it consistent and also store the breaking event address in case of manual program interrupt injection.
