From 49ea06957bf637b28aa338fba26432d5bafdeb99 Mon Sep 17 00:00:00 2001 From: Scott Wood Date: Mon, 28 Mar 2011 15:01:24 -0500 Subject: [PATCH] KVM: PPC: fix exit accounting for SPRs, tlbwe, tlbsx The exit type setting for mfspr/mtspr is moved from 44x to toplevel SPR emulation. This enables it on e500, and makes sure that all SPRs are covered. Exit accounting for tlbwe and tlbsx is added to e500.
