Merge branch 'timers-nohz-for-linus' of git://
Pull NOHZ changes from Ingo Molnar: "This tree adds full dynticks support to KVM guests (support the disabling of the timer tick on the guest). The main missing piece was the recognition of guest execution as RCU extended quiescent state and related changes" * 'timers-nohz-for-linus' of git:// kvm,rcu,nohz: use RCU extended quiescent state when running KVM guest context_tracking: Export context_tracking_user_enter/exit context_tracking: Run vtime_user_enter/exit only when state == CONTEXT_USER context_tracking: Add stub context_tracking_is_enabled context_tracking: Generalize context tracking APIs to support user and guest context_tracking: Rename context symbols to prepare for transition state ppc: Remove unused cpp symbols in kvm headers
