Subject: [PATCH 0/2] make kvm guest mode to be rcu quiescent state

CPU may spend a lot of time in a guest mode while other CPUs wait for
rcu grace period to elapse. This patch series makes guest mode into
quiescent state to shorten wait time.

Gleb Natapov (2):
  rcu: provide rcu_virt_note_context_switch() function.
  KVM: make guest mode entry to be rcu quiescent state
