Subject: [PATCH 1/8] powerpc/pseries: hypervisor facility unavailable use correct handler
Date: Tue, 13 Sep 2016 13:08:39 +1000 [thread overview]
Message-ID: <20160913030846.29790-2-npiggin@gmail.com> (raw)
In-Reply-To: <20160913030846.29790-1-npiggin@gmail.com>
The 0xf80 hv_facility_unavailable trampoline branches to the 0xf60
handler. This works because they both do the same thing, but it should
be fixed.
