Pull ARM SoC fixes from Olof Johansson:
 "We didn't have any fixes sent up for -rc2, so this is a slightly
  larger batch.  A bit all over the place platform-wise; OMAP, at91,
  marvell, renesas, sunxi, ux500, etc.

  I tried to summarize highlights but there isn't a whole lot to point
  out.  Lots of little things fixed all over.  A couple of defconfig
  updates due to new/changing options."

<title>serial: 8250_dw: Add valid clk pointer check</title>

Commit ffc3ae6dd "serial: 8250_dw: Enable runtime PM" introduced runtime
PM management, which enables/disables the clk without checking if the clk
is valid. However, this driver allows to be probed without a defined clk,
using clock-frequency, as a fallback.

Therefore, on platforms that are device tree probed using clock-frequency
instead of clk, we get an ugly NULL pointer dereference.

This patch fixes it by simply adding a check before accessing the clk api.

UART IP slave idle handling now taken care by runtime pm backend(hwmod layer)
so remove the hackery from the driver.

As discussed on the list, in future if dma mode needs to be brought
back to this driver, UART sysc handling needs to be updated in
framework such a way that no-idle/force idle profile can be supported.
Given the broken dma mode for OMAP uarts, its very unlikely.

Pull MIPS updates from Ralf Baechle:

 - More work on DT support for various platforms

 - Various fixes that were to late to make it straight into 3.9

 - Improved platform support, in particular the Netlogic XLR and
   BCM63xx, and the SEAD3 and Malta eval boards.

 - Support for several Ralink SOC families.

 - Complete support for the microMIPS ASE which basically reencodes the
   existing MIPS32/MIPS64 ISA to use non-constant size instructions.

 - Some fallout from LTO work which remove old cruft and will generally
   make the MIPS kernel easier to maintain and resistant to compiler
   optimization, even in absence of LTO.

 - KVM support.  While MIPS has announced hardware virtualization
   extensions this KVM extension uses trap and emulate mode for
   virtualization of MIPS32.  More KVM work to add support for VZ
   hardware virtualizaiton extensions and MIPS64 will probably already
   be merged for 3.11.

Most of this has been sitting in -next for a long time.  All defconfigs
have been build or run time tested except three for which fixes are being
sent by other maintainers.

Semantic conflict with kvm updates done as per Ralf
