        before my family vacation, and this code has not even been in
        linux-next as far as I can tell. But Logan Gunthorpe pleaded for its
        inclusion because the Switchtec driver has apparently been around for
        a while, just never in linux-next - Linus ]

      clean up x86 platform driver default values · 0192f175
      Linus Torvalds authored
      
      
      The updates this merge window added several bogus default enablement for
      new features.  We don't do that.  If people want new behavior, they ask
      for it.
      
      One 'default n' was also removed as pointless.  That's great, but there
      were eight other ones in the same file that were left alone.
      
      Fix it up.

      Pull x86 platform driver updates from Andy Shevchenko:
       "Here is the collected material against Platform Drivers x86 subsystem.
        It's rather bit busy cycle for PDx86, mostly due to Dell SMBIOS driver
        activity
      
        For this cycle we have quite an update for the Dell SMBIOS driver
        including WMI work to provide an interface for SMBIOS tokens via sysfs
        and WMI support for 2017+ Dell laptop models. SMM dispatcher code is
        split into a separate driver followed by a new WMI dispatcher. The
        latter provides a character device interface to user space.
      
        The git history also contains a merge of immutable branch from Wolfram
        Sang in order to apply a dependent fix to the Intel CherryTrail
        Battery Management driver.
      
        Other Intel drivers got a lot of cleanups. The Turbo Boost Max 3.0
        support is added for Intel Skylake.
      
        Peaq WMI hotkeys driver gets its own maintainer and white list of
        supported models.
      
        Silead DMI is expanded to support few additional platforms.
      
        Tablet mode via GMMS ACPI method is added to support some ThinkPad

      platform/x86: silead_dmi: Add silead, home-button property to some tablets · aaa40965
      Hans de Goede authored
      
      
      Add "silead,home-button" property to entries for tablets which have
      a capacitive home button (typically a windows logo on the front).
      
      This new property is checked for by the new capacitive home button
      support in the silead touchscreen driver.

      Pull clk updates from Stephen Boyd:
       "We have two changes to the core framework this time around.
      
        The first being a large change that introduces runtime PM support to
        the clk framework. Now we properly call runtime PM operations on the
        device providing a clk when the clk is in use. This helps on SoCs
        where the clks provided by a device need something to be powered on
        before using the clks, like power domains or regulators. It also helps
        power those things down when clks aren't in use.
      
        The other core change is a devm API addition for clk providers so we
        can get rid of a bunch of clk driver remove functions that are just
        doing of_clk_del_provider().
      
        Outside of the core, we have the usual addition of clk drivers and
        smattering of non-critical fixes to existing drivers. The biggest diff
        is support for Mediatek MT2712 and MT7622 SoCs, but those patches
        really just add a bunch of data.
      
        By the way, we're trying something new here where we build the tree up
        with topic branches. We plan to work this into our workflow so that we
        don't step on each other's toes, and so the fixes branch can be merged
        on an as-needed basis.
      
        Summary:
      
        Core:
         - runtime PM support for clk providers
         - devm API for of_clk_add_hw_provider()
      
        New Drivers:
         - Mediatek MT2712 and MT7622
         - Renesas R-Car V3M SoC
      
        Updates:
         - runtime PM support for Samsung exynos5433/exynos4412 providers
         - removal of clkdev aliases on Samsung SoCs
         - convert clk-gpio to use gpio descriptors
         - various driver cleanups to match kernel coding style
         - Amlogic Video Processing Unit VPU and VAPB clks
         - sigma-delta modulation for Allwinner audio PLLs
         - Allwinner A83t Display clks
         - support for the second display unit clock on Renesas RZ/G1E
         - suspend/resume support for Renesas R-Car Gen3 CPG/MSSR
         - new clock ids for Rockchip rk3188 and rk3368 SoCs
         - various 'const' markings on clk_ops structures
         - RPM clk support on Qualcomm MSM8996/MSM8660 SoCs"

      Pull Kbuild updates from Masahiro Yamada:
       "One of the most remarkable improvements in this cycle is, Kbuild is
        now able to cache the result of shell commands. Some variables are
        expensive to compute, for example, $(call cc-option,...) invokes the
        compiler. It is not efficient to redo this computation every time,
        even when we are not actually building anything. Kbuild creates a
        hidden file ".cache.mk" that contains invoked shell commands and their
        results. The speed-up should be noticeable.

      There is no need to #define the license of the driver, just put it in
      the MODULE_LICENSE() line directly as a text string.
      
      This allows tools that check that the module license matches the source
      code license to work properly, as there is no need to unwind the
      unneeded dereference.

      ipvlan: NULL pointer dereference panic in ipvlan_port_destroy · fe18da60
      Girish Moodalbail authored
      When call to register_netdevice() (called from ipvlan_link_new()) fails,
      we call ipvlan_uninit() (through ndo_uninit()) to destroy the ipvlan
      port. After returning unsuccessfully from register_netdevice() we go
      ahead and call ipvlan_port_destroy() again which causes NULL pointer
      dereference panic. Fix the issue by making ipvlan_init() and
      ipvlan_uninit() call symmetric.
      
      The ipvlan port will now be created inside ipvlan_init() and will be
      destroyed in ipvlan_uninit().

      route: also update fnhe_genid when updating a route cache · cebe84c6
      Xin Long authored
      Now when ip route flush cache and it turn out all fnhe_genid != genid.
      If a redirect/pmtu icmp packet comes and the old fnhe is found and all
      it's members but fnhe_genid will be updated.
      
      Then next time when it looks up route and tries to rebind this fnhe to
      the new dst, the fnhe will be flushed due to fnhe_genid != genid. It
      causes this redirect/pmtu icmp packet acutally not to be applied.
      
      This patch is to also reset fnhe_genid when updating a route cache.

      route: update fnhe_expires for redirect when the fnhe exists · e39d5246
      Xin Long authored
      Now when creating fnhe for redirect, it sets fnhe_expires for this
      new route cache. But when updating the exist one, it doesn't do it.
      It will cause this fnhe never to be expired.
      
      Paolo already noticed it before, in Jianlin's test case, it became
      even worse:
      
      When ip route flush cache, the old fnhe is not to be removed, but
      only clean it's members. When redirect comes again, this fnhe will
      be found and updated, but never be expired due to fnhe_expires not
      being set.
      
      So fix it by simply updating fnhe_expires even it's for redirect.
