From 324b3e63167bce69e6622c2be182595790bf7e38 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 4 Jan 2013 18:28:51 +0100 Subject: KVM: PPC: BookE: Add EPR ONE_REG sync We need to be able to read and write the contents of the EPR register from user space. This patch implements that logic through the ONE_REG API and declares its (never implemented) SREGS counterpart as deprecated.
