       "People are back from the holiday breaks, and it shows.  Here are a
        bunch of fixes for a number of platforms:
         - A couple of small fixes for Nomadik
         - A larger set of changes for kirkwood/mvebu
           - uart driver selection, dt clocks, gpio-poweroff fixups, a few
             __init annotation fixes and some error handling improvement in
             their xor dma driver.
         - i.MX had a couple of minor fixes (and a critical one for flexcan2
           clock setup)
         - MXS has a small board fix and a framebuffer bugfix
         - A set of fixes for Samsung Exynos, fixing default bootargs and some
           Exynos5440 clock issues
         - A set of OMAP changes including PM fixes and a few sparse warning
           fixups
      
        All in all a bit more positive code delta than we'd ideally want to
        see here, mostly from the OMAP PM changes, but nothing overly crazy."

      s390/3215: partially revert tty close handling fix · 6673cd0b
      Heiko Carstens authored
      Partially revert ae289dc1 "s390/3215: fix tty close handling", since this
      leads sometimes to hanging agetty processes and therefore systems that get
      stuck while starting.
      
      This was magically fixed (bisected) by a common code patch from Alan Cox:
      36b3c070 "tty: Move the handling of the tty release logic", however it was
      unrelated.
      
      Since the removed code worked for a decade, nobody knows anymore why it was
      in there in the first place and debugging the observed hang is non-trivial
      (at least for me :) ), let's just re-add the removed code before we see
      other side effects.

      s390/irq: remove split irq fields from /proc/stat · 420f42ec
      Heiko Carstens authored
      Now that irq sum accounting for /proc/stat's "intr" line works again we
      have the oddity that the sum field (first field) contains only the sum
      of the second (external irqs) and third field (I/O interrupts).
      The reason for that is that these two fields are already sums of all other
      fields. So if we would sum up everything we would count every interrupt
      twice.
      This is broken since the split interrupt accounting was merged two years
      ago: 052ff461 "[S390] irq: have detailed
      statistics for interrupt types".
      To fix this remove the split interrupt fields from /proc/stat's "intr"
      line again and only have them in /proc/interrupts.
      
      This restores the old behaviour, seems to be the only sane fix and mimics
      a behaviour from other architectures where /proc/interrupts also contains
      more than /proc/stat's "intr" line does.

      s390/irq: enable irq sum accounting for /proc/stat again · add9bde2
      Heiko Carstens authored
      For more than two years, since f2c66cd8
      "/proc/stat: scalability of irq num per cpu" the output of /proc/stat is
      broken.
      The first field in the "intr" line should contain the sum of all interrupts,
      however since the above mentioned change it is always zero.
      
      The reason for that is that a per cpu irq sum variable had been introduced
      which got incremented when calling kstat_incr_irqs_this_cpu(). However
      on s390 we directly incremented only the per cpu per irq counter by accessing
      the array element via kstat_cpu(smp_processor_id()).irqs[...].
      So fix this and use the kstat_incr_irqs_this_cpu() wrapper which increments
      both: the per cpu per irq counter and the per cpu irq sum counter.

      s390/smp: fix section mismatch for smp_add_present_cpu() · eba61970
      Heiko Carstens authored
      Fixes this section mismatch:
      
      WARNING: vmlinux.o(.text+0x145e4): Section mismatch in reference from the function
         smp_add_present_cpu() to the function .cpuinit.text:register_cpu()
      The function smp_add_present_cpu() references
      the function __cpuinit register_cpu().
      This is often because smp_add_present_cpu lacks a __cpuinit
      annotation or the annotation of register_cpu is wrong.

      s390/debug: Fix s390dbf lockdep problem in debug_(un)register_view() · 5a334c08
      Michael Holzheu authored
      The debug_register/unregister_view() functions call debugfs_remove()
      while holding the debug_info spinlock. Because debugfs_remove() takes
      a mutex and therefore can sleep this is not allowed. To fix the problem
      we give up the debug_info lock before calling debugfs_remove().
      
      The following shows the lockdep message:
      
      [ INFO: possible circular locking dependency detected ]
      -------------------------------------------------------
      rmmod/4379 is trying to acquire lock:

      but task is already holding lock:
