      Pull RCU updates from Ingo Molnar:
       "The main RCU changes in this cycle are:
      
         - the combination of tree geometry-initialization simplifications and
           OS-jitter-reduction changes to expedited grace periods.  These two
           are stacked due to the large number of conflicts that would
           otherwise result.
      
         - privatize smp_mb__after_unlock_lock().
      
           This commit moves the definition of smp_mb__after_unlock_lock() to
           kernel/rcu/tree.h, in recognition of the fact that RCU is the only
           thing using this, that nothing else is likely to use it, and that
           it is likely to go away completely.
      
         - documentation updates.
      
         - torture-test updates.
      
         - misc fixes"

        make the code smaller and avoid some potential bugs.
      
        Otherwise another fairly quiet release for the regulator API,

         - a new API for setting voltages based on a minimum, target, maximum

      Pull kvm updates from Paolo Bonzini:
       "A very small release for x86 and s390 KVM.
      
         - s390: timekeeping changes, cleanups and fixes
      
         - x86: support for Hyper-V MSRs to report crashes, and a bunch of
           cleanups.
      
        One interesting feature that was planned for 4.3 (emulating the local
        APIC in kernel while keeping the IOAPIC and 8254 in userspace) had to
        be delayed because Intel complained about my reading of the manual"

      alpha: select CONFIG_ARCH_USE_CMPXCHG_LOCKREF. · 8f8dcb3f
      Matt Turner authored
      On Alpha we have spinlocks that are 32b in size and an efficient
      cmpxchg64 implementation, so we qualify to make use of cmpxchg backed
      lockrefs. Select the ARCH_USE_CMPXCHG_LOCKREF Kconfig symbol and provide
      a trivial implementation of arch_spin_value_unlocked to satisfy the
      lockref code.
