From 891219a9d3958860b915021f622f7119b9b880d8 Mon Sep 17 00:00:00 2001 From: Tim Deegan Date: Thu, 27 Feb 2014 15:06:33 +0000 Subject: [PATCH] x86/hvm: assert that we we saved a sane number of MSRs. Just as a backstop measure against later changes that add MSRs to the save function without updating the count in the init function.
