From 5ee86c4190f9e19a9e13906389069c73d7f75bfb Mon Sep 17 00:00:00 2001
From: Ben Skeggs <bskeggs@redhat.com>
Date: Mon, 1 Jul 2013 14:32:42 +1000
Subject: drm/nve0-/gr: some new gpc registers can have multiple copies

GK110 exposes more than one, and needs to be dealt with in the ctxsw
ucode just like the TPC sets are.

Broadcast is at +0xe00.
