Subject: [PATCH 1/5] powerpc: Fix hypervisor facility unavaliable vector number
Date: Fri, 9 Aug 2013 17:29:27 +1000 [thread overview]
Message-ID: <1376033371-28713-1-git-send-email-mikey@neuling.org> (raw)
In-Reply-To: <25550.1375872955@ale.ozlabs.ibm.com>
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.
