      imx-drm updates and encoder atomic_mode_set helper callback
      
      - add pixel clock and DE polarity configuration from device tree
        using display timing bindings for parallel and LVDS output
      - cleanup/remove trivial functions
      - cleanup and fixes in preparation for capture support
      - add atomic_mode_set helper and use it in imx-ldb - this is an
        alternative to the encoder mode_set callback that passes the
        crtc and connector state instead of just the mode. It allows
        drivers to get information from the attached connector without
        having to iterate over all connectors

      Pull power management fixes from Rafael Wysocki:
       "Two hibernation fixes allowing it to work with the recently added
        randomization of the kernel identity mapping base on x86-64 and one
        cpufreq driver regression fix.
      
        Specifics:
      
         - Fix the x86 identity mapping creation helpers to avoid the
           assumption that the base address of the mapping will always be
           aligned at the PGD level, as it may be aligned at the PUD level if
           address space randomization is enabled (Rafael Wysocki).
      
         - Fix the hibernation core to avoid executing tracing functions
           before restoring the processor state completely during resume

      PM / hibernate: Restore processor state before using per-CPU variables · 62822e2e
      Thomas Garnier authored
      Restore the processor state before calling any other functions to
      ensure per-CPU variables can be used with KASLR memory randomization.
      
      Tracing functions use per-CPU variables (GS based on x86) and one was
      called just before restoring the processor state fully. It resulted
      in a double fault when both the tracing & the exception handler
      functions tried to use a per-CPU variable.
      
      Fixes: bb3632c6 (PM / sleep: trace events for suspend/resume)

      nfsd: don't return an unhashed lock stateid after taking mutex · dd257933
      Jeff Layton authored
      nfsd4_lock will take the st_mutex before working with the stateid it
      gets, but between the time when we drop the cl_lock and take the mutex,
      the stateid could become unhashed (a'la FREE_STATEID). If that happens
      the lock stateid returned to the client will be forgotten.
      
      Fix this by first moving the st_mutex acquisition into
      lookup_or_create_lock_state. Then, have it check to see if the lock
      stateid is still hashed after taking the mutex. If it's not, then put
      the stateid and try the find/create again.
