If anyone has any objections, please let me know. ------------------ From: Michael Neuling commit 88f094120bd2f012ff494ae50a8d4e0d8af8f69e upstream. Currently if we take hypervisor facility unavaliable (from 0xf80/0x4f80) we mark it as an OS facility unavaliable (0xf60) as the two share the same code path. The becomes a problem in facility_unavailable_exception() as we aren't able to see the hypervisor facility unavailable exceptions. Below fixes this by duplication the required macros.
