      Pull ARM DT updates from Arnd Bergmann:
       "Lots of changes as usual, so I'm trying to be brief here. Most of the
        new hardware support has the respective driver changes merged through
        other trees or has had it available for a while, so this is where
        things come together.
      
        We get a DT descriptions for a couple of new SoCs, all of them
        variants of other chips we already support, and usually coming with a
        new evaluation board:
      
         - Oxford semiconductor (now Broadcom) OX820 SoC for NAS devices
         - Qualcomm MDM9615 LTE baseband
         - NXP imx6ull, the latest and smallest i.MX6 application processor variant
         - Renesas RZ/G (r8a7743 and r8a7745) application processors
         - Rockchip PX3, a variant of the rk3188 chip used in Android tablets
         - Rockchip rk1108 single-core application processor
         - ST stm32f746 Cortex-M7 based microcontroller
         - TI DRA71x automotive processors
      
        These are commercially available consumer platforms we now support:
      
         - Motorola Droid 4 (xt894) mobile phone
         - Rikomagic MK808 Android TV stick based on Rockchips rx3066
         - Cloud Engines PogoPlug v3 based on OX820
         - Various Broadcom based wireless devices:
            - Netgear R8500 router
            - Tenda AC9 router
            - TP-LINK Archer C9 V1
            - Luxul XAP-1510 Access point
         - Turris Omnia open hardware router based on Armada 385
      
        And a couple of new boards targeted at developers, makers or
        industrial integration:
      
         - Macnica Sodia development platform for Altera socfpga (Cyclone V)
         - MicroZed board based on Xilinx Zynq FPGA platforms
         - TOPEET itop/elite based on exynos4412
         - WP8548 MangOH Open Hardware platform for IOT, based on Qualcomm MDM9615
         - NextThing CHIP Pro gadget
         - NanoPi M1 development board
         - AM571x-IDK industrial board based on TI AM5718
         - i.MX6SX UDOO Neo
         - Boundary Devices Nitrogen6_SOM2 (i.MX6)
         - Engicam i.CoreM6
         - Grinn i.MX6UL liteSOM/liteBoard
         - Toradex Colibri iMX6 module
      
        Other changes:
      
         - added peripherals on renesas, davinci, stm32f429, uniphier, sti,
           mediatek, integrator, at91, imx, vybrid, ls1021a, omap, qualcomm,
           mvebu, allwinner, broadcom, exynos, zynq
      
         - Continued fixes for W=1 dtc warnings
      
         - The old STiH415/416 SoC support gets removed, these never made it
           into products and have served their purpose in the kernel as a
           template for teh newer chips from ST
      
         - The exynos4415 dtsi file is removed as nothing uses it.
      
         - Intel PXA25x can now be booted using devicetree"

       "Changes to platform code for 64-bit ARM platforms. We are not adding
        any new platforms that require code or Kconfig changes this time, so
        it's basically just defconfig changes to enable support for more
        drivers used on the existing platforms.
      
        This is mainly interesting for the Raspberry Pi 3, which should now
        work much better with the default build"

      Pull ARM SoC platform updates from Arnd Bergmann:
       "These are updates for platform specific code on 32-bit ARM machines,
        essentially anything that can not (yet) be expressed using DT files.
      
        Noteworthy changes include:
      
         - Added support for the TI DRA71x family of SoCs in mach-omap2, this
           is an new variant of the the DRA72x/DRA74x automotive infotainment
           chips we already supported for a while.
      
         - Added support for the ST STM32F746 SoC, the first Cortex-M7 based
           microcontroller we support, related to the smaller STM32F4 family.
      
         - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile, see
           http://elinux.org/RZ-G
      
         - SMP is now supported on the OX820 platform
      
         - A lot of code in mach-omap2 gets removed as a follow-up to removing
           support for board files in the previous release
      
         - Davinci has some new work to improve USB support
      
         - For i.MX, the performance monitor now supports profiling the memory

       "As usual, we queue up a few fixes that don't seem urgent enough to go
        in through -rc, or that just came a little too late given their size.
      
        The zx fixes make the platform finally boot on real hardware, the
        davinci and imx31 get the DT support working better for some of the
        machines that are still normally used with classic board files. One
        tegra fix is important for new bootloader versions, but the bug has
        been around for a while without anyone noticing.

      Linus Torvalds authored
      Pull i2c updates from Wolfram Sang:
      
       - the first series of making i2c_device_id optional instead of
         mandatory (in favor of alternatives like of_device_id).
      
         This involves adding a new probe callback (probe_new) which removes
         some peculiarities I2C had for a long time now. The new probe is
         matching the other subsystems now and the old one will be removed
         once all users are converted. It is expected to take a while but
         there is ongoing interest in that.
      
       - SMBus Host Notify introduced 4.9 got refactored. They are now using
         interrupts instead of the alert callback which solves multiple
         issues.
      
       - new drivers for iMX LowPower I2C, Mellanox CPLD and its I2C mux
      
       - significant refactoring for bcm2835 driver

      This turns out to be a false positive as the pr_info call cannot be
      reached if tp_features.hotkey_tablet (global scope) is 0, and
      in_tablet_mode and type are assigned in both places
      tp_features.hotkey_tablet is assigned.
      
      Regardless, to make it explicit and avoid further reports, initialize
      in_tablet_mode to 0 and type to NULL.

      redo: radix tree test suite: fix compilation · b9a0deb9
      Matthew Wilcox authored
      [ This resurrects commit 53855d10, which was reverted in
        2b41226b.  It depended on commit d544abd5 ("lib/radix-tree:
        Convert to hotplug state machine") so now it is correct to apply ]
      
      Patch "lib/radix-tree: Convert to hotplug state machine" breaks the test
      suite as it adds a call to cpuhp_setup_state_nocalls() which is not
      currently emulated in the test suite.  Add it, and delete the emulation
      of the old CPU hotplug mechanism.

      printk: remove console flushing special cases for partial buffered lines · 5c2992ee
      Linus Torvalds authored
      It actively hurts proper merging, and makes for a lot of special cases.
      There was a good(ish) reason for doing it originally, but it's getting
      too painful to maintain.  And most of the original reasons for it are
      long gone.
      
      So instead of having special code to flush partial lines to the console
      (as opposed to the record buffers), do _all_ the console writing from
      the record buffer, and be done with it.
      
      If an oops happens (or some other synchronous event), we will flush the
      partial lines due to the oops printing activity, so this does not affect
      that.  It does mean that if you have a completely hung machine, a
      partial preceding line may not have been printed out.
      
      That was some of the original reason for this complexity, in fact, back
      when we used to test for the historical i386 "halt" instruction problem
      by doing
      
      	pr_info("Checking 'hlt' instruction... ");
      
      	if (!boot_cpu_data.hlt_works_ok) {
      		pr_cont("disabled\n");
      		return;
      	}
      	halt();
      	halt();
      	halt();
      	halt();
      	pr_cont("OK\n");
      
      and that model no longer works (it the 'hlt' instruction kills the
      machine, the partial line won't have been flushed, so you won't even see
      it).
      
      Of course, that was also back in the days when people actually had
      textual console output rather than a graphical splash-screen at bootup.
      How times change..

      printk: remove games with previous record flags · 5aa068ea
      Linus Torvalds authored
      The record logging code looks at the previous record flags in various
      ways, and they are all wrong.
      
      You can't use the previous record flags to determine anything about the
      next record, because they may simply not be related.  In particular, the
      reason the previous record was a continuation record may well be exactly
      _because_ the new record was printed by a different process, which is
      why the previous record was flushed.
      
      So all those games are simply wrong, and make the code hard to
      understand (because the code fundamentally cdoes not make sense).
      
      So remove it.

      docs: add back 'Documentation/Changes' file (as symlink) · 852d21ae
      Linus Torvalds authored
      Jaegeuk Kim reports that the debian kernel package build gets confused
      by the lack of Documentation/Changes file.  We also refer to that path
      name in ver_linux and various how-to files and Kconfig files.
      
      The file got renamed away in commit 186128f7 ("docs-rst: add
      documents to development-process"), and as Jaegeuk Kim points out, the
      commit message for that change says "use symlinks instead of renames",
      but then the commit itself actually does renames after all.
      
      Maybe we should do the other files too, but for now this just adds the
      minimal symlink back to the historical name, so that people looking for
      Documentation/Changes will actually find what they are looking for, and
      the debian scripts continue to work.

      radix-tree: ensure counts are initialised · e8de4340
      Matthew Wilcox authored
      radix_tree_join() was freeing nodes with a non-zero ->exceptional count,
      and radix_tree_split() wasn't zeroing ->exceptional when it allocated
      the new node.  Fix this by making all callers of radix_tree_node_alloc()
      pass in the new counts (and some other always-initialised fields), which
      will prevent the problem recurring if in future we decide to do

      radix tree test suite: cache recently freed objects · bbe9d71f
      Matthew Wilcox authored
      The kmem_cache_alloc implementation simply allocates new memory from
      malloc() and calls the ctor, which zeroes out the entire object.  This
      means it cannot spot bugs where the object isn't properly reinitialised
      before being freed.
      
      Add a small (11 objects) cache before freeing objects back to malloc.
      This is enough to let us write a test to catch it, although the memory
      allocator is now aware of the structure of the radix tree node, since it
      chains free objects through ->private_data (like the percpu cache does).

      idr: reduce the number of bits per level from 8 to 6 · 424251a4
      Matthew Wilcox authored
      In preparation for merging the IDR and radix tree, reduce the fanout at
      each level from 256 to 64.  If this causes a performance problem then a
      bisect will point to this commit, and we'll have a better idea about
      what we might do to fix it.
