      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.12 kernel cycle.
      
        Core changes:
      
         - Return NULL from gpiod_get_optional() when GPIOLIB is disabled.
           This was a much discussed change. It affects use cases where people
           write drivers that might or might not be using GPIO resources. I
           have decided that this is the lesser evil right now.
      
         - Make gpiod_count() behave consistently across different hardware
           descriptions.
      
         - Fix the syntax around open drain/open source to not infer active
           high/low semantics.
      
        New drivers:
      
         - A new single-register fixed-direction framework driver for hardware
           that have lines controlled by a single register that just work in
           one direction (out or in), including IRQ support.
      
         - Support the Fintek F71889A GPIO SuperIO controller.
      
         - Support the National NI 169445 MMIO GPIO.
      
         - Support for the X-Gene derivative of the DWC GPIO controller
      
         - Support for the Rohm BD9571MWV-M PMIC GPIO controller.
      
         - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver
           and replace both the Gemini and the Moxa ART custom drivers with
           this driver.
      
        Driver improvements:
      
         - A whole slew of drivers have their spinlocks chaned to raw
           spinlocks as they provide irqchips, and thus we are progressing on
           realtime compliance.
      
         - Use devm_irq_alloc_descs() in a slew of drivers, getting managed
           resources.
      
         - Support for the embedded PWM controller inside the MVEBU driver.
      
         - Debounce, open source and open drain support for the Aspeed driver.
      
         - Misc smaller fixes like spelling and syntax and whatnot"

      Pull x86 platform-drivers update from Darren Hart:
       "This represents a significantly larger and more complex set of changes
        than those of prior merge windows.
      
        In particular, we had several changes with dependencies on other
        subsystems which we felt were best managed through merges of immutable
        branches, including one each from input, i2c, and leds. Two patches
        for the watchdog subsystem are included after discussion with Wim and
        Guenter following a collision in linux-next (this should be resolved
        and you should only see these two appear in this pull request). These
        are called out in the "External" section below.
      
        Summary of changes:
         - significant further cleanup of fujitsu-laptop and hp-wmi
         - new model support for ideapad, asus, silead, and xiaomi

      Pull tracing updates from Steven Rostedt:
       "New features for this release:
      
         - Pretty much a full rewrite of the processing of function plugins.
           i.e. echo do_IRQ:stacktrace > set_ftrace_filter
      
         - The rewrite was needed to add plugins to be unique to tracing
           instances. i.e. mkdir instance/foo; cd instances/foo; echo
           do_IRQ:stacktrace > set_ftrace_filter The old way was written very
           hacky. This removes a lot of those hacks.
      
         - New "function-fork" tracing option. When set, pids in the
           set_ftrace_pid will have their children added when the processes
           with their pids listed in the set_ftrace_pid file forks.
      
         - Exposure of "maxactive" for kretprobe in kprobe_events
      
         - Allow for builtin init functions to be traced by the function
           tracer (via the kernel command line). Module init function tracing
           will come in the next release.
      
         - Added more selftests, and have selftests also test in an instance"

      Pull printk updates from Petr Mladek:
      
       - There is a situation when early console is not deregistered because
         the preferred one matches a wrong entry. It caused messages to appear
         twice.
      
         This is the 2nd attempt to fix it. The first one was wrong, see the
         commit c6c7d83b ('Revert "console: don't prefer first registered
         if DT specifies stdout-path"').
      
         The fix is coupled with some small code clean up. Well, the console
         registration code would deserve a big one. We need to think about it.
      
       - Do not lose information about the preemtive context when the console
         semaphore is re-taken.
      
       - Do not block CPU hotplug when someone else is already pushing
         messages to the console.
      
      * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/pmladek/printk:
        printk: fix double printing with earlycon
        printk: rename selected_console -> preferred_console
        printk: fix name/type/scope of preferred_console var
        printk: Correctly handle preemption in console_unlock()
        printk: use console_trylock() in console_cpu_notify()
