From 7ab7de87432c7d6544b8c1b45ba6520f4115539f Mon Sep 17 00:00:00 2001 From: Michael Neuling Date: Fri, 9 Aug 2013 17:29:27 +1000 Subject: powerpc: Fix hypervisor facility unavaliable vector number 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.
