From be43f83dada2cf0e9e01c9a0ba42977c5bd70f9d Mon Sep 17 00:00:00 2001 From: Sheng Yang <sheng@linux.intel.com> Date: Fri, 18 Dec 2009 16:48:45 +0800 Subject: x86: Raise vsyscall priority on hotplug notifier chain 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.
