Date: Wed, 10 Feb 2010 19:22:41 +0200 From: Avi Kivity <avi@...hat.com> To: kvm@...r.kernel.org Cc: linux-kernel@...r.kernel.org Subject: [PATCH 12/40] x86: Raise vsyscall priority on hotplug notifier chain From: Sheng Yang <sheng@...ux.intel.com> KVM need vsyscall_init() to initialize MSR_TSC_AUX before it read the value. Per Avi's suggestion, this patch raised vsyscall priority on hotplug notifier chain, to 30.
