From 2b15811c8cd4dbe8dcde32320936fe74e51e4279 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Tue, 25 Sep 2012 17:12:21 +0000 Subject: ppc/pseries: Reset VPA registration on CPU reset The ppc specific CPU state contains several variables which track the VPA, SLB shadow and dispatch trace log. These are structures shared between OS and hypervisor that are used on the pseries machine to track various per-CPU quantities. The address of these structures needs to be registered by the guest on each boot, however currently this registration is not cleared when we reset the cpu. This patch corrects this bug.
