       "Another week, another small batch of fixes.
        Most of these make zynq, socfpga and sunxi platforms work a bit
         - due to new requirements for regulators, DWMMC on socfpga broke past
         - SMP spinup fix for socfpga
         - a few DT fixes for zynq
         - another option (FIXED_REGULATOR) for sunxi is needed that used to
           be selected by other options but no longer is.
         - a couple of small DT fixes for at91

       "This is material that didn't make it to my 3.18-rc1 pull request for
        various reasons, mostly related to timing and travel (LinuxCon EU /
        LPC) plus a couple of fixes for recent bugs.
        The only really new thing here is the PM QoS class for memory
        bandwidth, but it is simple enough and users of it will be added in
        the next cycle.  One major change in behavior is that platform devices
        enumerated by ACPI will use 32-bit DMA mask by default.  Also included
        is an ACPICA update to a new upstream release, but that's mostly
        cleanups, changes in tools and similar.  The rest is fixes and
        cleanups mostly.
         - Fix for a recent PCI power management change that overlooked the
           fact that some IRQ chips might not be able to configure PCIe PME
           for system wakeup from Lucas Stach.
         - Fix for a bug introduced in 3.17 where acpi_device_wakeup() is
           called with a wrong ordering of arguments from Zhang Rui.
         - A bunch of intel_pstate driver fixes (all -stable candidates) from
           Dirk Brandewie, Gabriele Mazzotta and Pali Rohár.
         - Fixes for a rather long-standing problem with the OOM killer and
           the freezer that frozen processes killed by the OOM do not actually
           release any memory until they are thawed, so OOM-killing them is
           rather pointless, with a couple of cleanups on top (Michal Hocko,
           Cong Wang, Rafael J Wysocki).
         - ACPICA update to upstream release 20140926, inlcuding mostly
           cleanups reducing differences between the upstream ACPICA and the
           kernel code, tools changes (acpidump, acpiexec) and support for the
           _DDN object (Bob Moore, Lv Zheng).
         - New PM QoS class for memory bandwidth from Tomeu Vizoso.
         - Default 32-bit DMA mask for platform devices enumerated by ACPI
           (this change is mostly needed for some drivers development in
           progress targeted at 3.19) from Heikki Krogerus.

      arm64: Fix memblock current_limit with 64K pages and 48-bit VA · 3dec0fe4
      Catalin Marinas authored
      With 48-bit VA space, the 64K page configuration uses 3 levels instead
      of 2 and PUD_SIZE != PMD_SIZE. Since with 64K pages we only cover
      PMD_SIZE with the initial swapper_pg_dir populated in head.S, the
      memblock current_limit needs to be set accordingly in map_mem() to avoid
      allocating unmapped memory. The memblock current_limit is progressively
      increased as more blocks are mapped.
