      Pull power management fixes from Rafael Wysocki:
       "These fix a potential regression introduced during the 4.3 cycle
        (generic power domains framework), a nasty bug that has been present
        forever (power capping RAPL driver), a build issue (Tegra cpufreq
        driver) and a minor ugliness introduced recently (intel_pstate).
      
        Specifics:
      
         - Fix a potential regression in the generic power domains framework
           introduced during the 4.3 development cycle that may lead to
           spurious failures of system suspend in certain situations (Ulf
           Hansson).
      
         - Fix a problem in the power capping RAPL (Running Average Power
           Limits) driver that causes it to initialize successfully on some
           systems where it is not supposed to do that which is due to an
           incorrect check in an initialization routine (Prarit Bhargava).
      
         - Fix a build problem in the cpufreq Tegra driver that depends on the
           regulator framework, but that dependency is not reflected in
           Kconfig (Arnd Bergmann).
      
         - Fix a recent mistake in the intel_pstate driver where a numeric
           constant is used directly instead of a symbol defined specifically
           for the case in question (Prarit Bhargava)"

      Pull SCSI fixes from James Bottomley:
       "Three fixes this time, two in SES picked up by KASAN for various types
        of buffer overrun.  The first is a USB array which returns page 8
        whatever is asked for and causes us to overrun with incorrect data
        format assumptions and the second is an invalid iteration of page 10
        (the additional information page).
      
        The final fix is a reversion of a NULL deref fix which caused
        suspend/resume not to be called in pairs leading to incorrect device
        operation (Jens has queued a more proper fix for the problem in
        block)"

      Input: elants_i2c - fix wake-on-touch · 478e5ed1
      James Chen authored
      When sending "SLEEP" command to the controller it ceases scanning
      completely and is unable to wake the system up from sleep, so if it is
      configured as a wakeup source we should simply configure interrupt for
      wakeup and rely on idle logic within the controller to reduce power
      consumption while it is not used.

      This is because we mistake a raw socket as a tcp socket.
      We should check both sk->sk_type and sk->sk_protocol to ensure
      it is a tcp socket.
      
      Willem points out __skb_complete_tx_timestamp() needs to fix as well.

      Currently the Tx flow control is based on reading the hardware state,
      which is not accurate since it may not reflect the descriptors that
      are not yet reached the memory.

      af_unix: Revert 'lock_interruptible' in stream receive code · 3822b5c2
      Rainer Weikusat authored
      With b3ca9b02, the AF_UNIX SOCK_STREAM
      receive code was changed from using mutex_lock(&u->readlock) to
      mutex_lock_interruptible(&u->readlock) to prevent signals from being
      delayed for an indefinite time if a thread sleeping on the mutex
      happened to be selected for handling the signal. But this was never a
      problem with the stream receive code (as opposed to its datagram
      counterpart) as that never went to sleep waiting for new messages with the
      mutex held and thus, wouldn't cause secondary readers to block on the
      mutex waiting for the sleeping primary reader. As the interruptible
      locking makes the code more complicated in exchange for no benefit,
      change it back to using mutex_lock.
