From 8c95ead6039d46d2d5c375d3cadac8708121fbe4 Mon Sep 17 00:00:00 2001 From: Bharat Bhushan Date: Fri, 25 Jul 2014 11:32:43 +0530 Subject: KVM: PPC: Remove comment saying SPRG1 is used for vcpu pointer Scott Wood pointed out that We are no longer using SPRG1 for vcpu pointer, but using SPRN_SPRG_THREAD <=> SPRG3 (thread->vcpu). So this comment is not valid now. Note: SPRN_SPRG3R is not supported (do not see any need as of now), and if we want to support this in future then we have to shift to using SPRG1 for VCPU pointer.
