From dba69d1092e291e257fb5673a3ad0e4c87878ebc Mon Sep 17 00:00:00 2001 From: Marcelo Tosatti Date: Sun, 1 Apr 2012 13:53:36 -0300 Subject: x86, kvm: Call restore_sched_clock_state() only after %gs is initialized s2ram broke due to this KVM commit: b74f05d61b73 x86: kvmclock: abstract save/restore sched_clock_state restore_sched_clock_state() methods use percpu data, therefore they must run after %gs is initialized, but before mtrr_bp_restore() (due to lockstat using sched_clock). Move it to the correct place.
