Subject: powerpc: Fix hypervisor facility unavaliable vector number
From: Michael Neuling <mikey@xxxxxxxxxxx>
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.
