      Pull asm-generic fixes from Arnd Bergmann:
       "I have one regression fix for a minor build problem after the
        architecture removal series, plus a rework of the barriers in the
        readl/writel functions, thanks to work by Sinan Kaya:
      
        This started from a discussion on the linuxpcc and rdma mailing
        lists[1]. To summarize, we decided that architectures are responsible
        to serialize readl() and writel() accesses on a device MMIO space
        relative to DMA performed by that device.
      
        This series provides a pessimistic implementation of that behavior for
        asm-generic/io.h, which is in turn used by a number of architectures
        (h8300, microblaze, nios2, openrisc, s390, sparc, um, unicore32, and
        xtensa). Some of those presumably need no extra barriers, or something
        weaker than rmb()/wmb(), and they are advised to override the new
        default for better performance.
      
        For inb()/outb(), the same barriers are used, but architectures might
        want to add another barrier to outb() here if that can guarantee
        non-posted behavior (some architectures can, others cannot do that).
      
        The readl_relaxed()/writel_relaxed() family of functions retains the
        existing behavior with no extra barriers"

      Linus Torvalds authored
      Pull more power management updates from Rafael Wysocki:
       "These include one big-ticket item which is the rework of the idle loop
        in order to prevent CPUs from spending too much time in shallow idle
        states. It reduces idle power on some systems by 10% or more and may
        improve performance of workloads in which the idle loop overhead
        matters. This has been in the works for several weeks and it has been
        tested and reviewed quite thoroughly.
      
        Also included are changes that finalize the cpufreq cleanup moving
        frequency table validation from drivers to the core, a few fixes and
        cleanups of cpufreq drivers, a cpuidle documentation update and a PM
        QoS core update to mark the expected switch fall-throughs in it.
      
        Specifics:
      
         - Rework the idle loop in order to prevent CPUs from spending too
           much time in shallow idle states by making it stop the scheduler
           tick before putting the CPU into an idle state only if the idle
           duration predicted by the idle governor is long enough.
      
           That required the code to be reordered to invoke the idle governor
           before stopping the tick, among other things (Rafael Wysocki,
           Frederic Weisbecker, Arnd Bergmann).
      
         - Add the missing description of the residency sysfs attribute to the
           cpuidle documentation (Prashanth Prakash).
      
         - Finalize the cpufreq cleanup moving frequency table validation from
           drivers to the core (Viresh Kumar).
      
         - Fix a clock leak regression in the armada-37xx cpufreq driver
           (Gregory Clement).
      
         - Fix the initialization of the CPU performance data structures for
           shared policies in the CPPC cpufreq driver (Shunyong Yang).
      
         - Clean up the ti-cpufreq, intel_pstate and CPPC cpufreq drivers a
           bit (Viresh Kumar, Rafael Wysocki).
      
         - Mark the expected switch fall-throughs in the PM QoS core (Gustavo
           Silva)"

      ====================
      l2tp: tunnel creation fixes
      
      L2TP tunnel creation is racy. We need to make sure that the tunnel
      returned by l2tp_tunnel_create() isn't going to be freed while the
      caller is using it. This is done in patch #1, by separating tunnel
      creation from tunnel registration.
      
      With the tunnel registration code in place, we can now check for
      duplicate tunnels in a race-free way. This is done in patch #2, which
      incidentally removes the last use of l2tp_tunnel_find().

      l2tp: fix race in duplicate tunnel detection · f6cd651b
      Guillaume Nault authored
      We can't use l2tp_tunnel_find() to prevent l2tp_nl_cmd_tunnel_create()
      from creating a duplicate tunnel. A tunnel can be concurrently
      registered after l2tp_tunnel_find() returns. Therefore, searching for
      duplicates must be done at registration time.
      
      Finally, remove l2tp_tunnel_find() entirely as it isn't use anywhere
      anymore.
