From 8b75cbbe647603f2b3c17ead35ee3cefa88397e7 Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Fri, 20 Sep 2013 14:52:37 +1000 Subject: [PATCH] KVM: PPC: BookE: Add GET/SET_ONE_REG interface for VRSAVE This makes the VRSAVE register value for a vcpu accessible through the GET/SET_ONE_REG interface on Book E systems (in addition to the existing GET/SET_SREGS interface), for consistency with Book 3S.
