         - A fixup for a build breakage that hits on arm64 allmodconfig in
           QCOM SCM firmware drivers
         - MMC fixes for OMAP that had quite a bit of breakage this merge

      Fixes for omaps for v4.3-rc cycle:
      
      - Two more patches to fix most of the MMC regressions with the
        PBIAS regulator changes. At least two MMC driver related issues
        still seems to remain for omap3 legacy booting and omap4 duovero.
        Note that the dts changes depend on a recent regulator fix, and
        are based on the regulator commit now in mainline kernel
      
      - Enable autoidle for am43xx clocks to prevent clocks from staying
        always on
      
      - Fix i2c5 pinctrl offsets for omap5-uevm

      Prior to the VRF change the oif was not set in the flow struct, so the
      VRF support should really have only added the vrf_master_ifindex lookup.

      IB/ipoib: increase the max mcast backlog queue · 2866196f
      Doug Ledford authored
      When performing sendonly joins, we queue the packets that trigger
      the join until the join completes.  This may take on the order of
      hundreds of milliseconds.  It is easy to have many more than three
      packets come in during that time.  Expand the maximum queue depth
      in order to try and prevent dropped packets during the time it
      takes to join the multicast group.

      Pull another cgroup fix from Tejun Heo:
       "The cgroup writeback support got inadvertently enabled for traditional
        hierarchies revealing two regressions which are currently being worked
        on.  It shouldn't have been enabled on traditional hierarchies, so
        disable it on them.  This is enough to make the regressions go away
        for people who aren't experimenting with cgroup"

      ppp: fix lockdep splat in ppp_dev_uninit() · 58a89eca
      Guillaume Nault authored
      ppp_dev_uninit() locks all_ppp_mutex while under rtnl mutex protection.
      ppp_create_interface() must then lock these mutexes in that same order
      to avoid possible deadlock.
