When NO_IOMEM is enabled (e.g. score architecture), some drivers which
need HAS_IOMEM need notice about it, or it will report related warning:

  warning: (GPIO_SCH && GPIO_ICH && GPIO_VX855 && GPIO_RDC321X && IE6XX_WDT && RADIO_WL1273 && HID_SENSOR_HUB && MFD_NVEC) selects MFD_CORE which has unmet direct dependencies (HAS_IOMEM)

dyn_callback_lock is being taken from IRQ context through hid_irq_in() ->
hid_input_report() -> sensor_hub_raw_event() -> sensor_hub_get_callback(),
therefore anyone else acquiring it needs to disable IRQs to disable deadlocks.

Pull KVM updates from Paolo Bonzini:
 "At over 200 commits, covering almost all supported architectures, this
  was a pretty active cycle for KVM.  Changes include:

   - a lot of s390 changes: optimizations, support for migration, GDB
     support and more

   - ARM changes are pretty small: support for the PSCI 0.2 hypercall
     interface on both the guest and the host (the latter acked by
     Catalin)

   - initial POWER8 and little-endian host support

   - support for running u-boot on embedded POWER targets

   - pretty large changes to MIPS too, completing the userspace
     interface and improving the handling of virtualized timer hardware

   - for x86, a larger set of changes is scheduled for 3.17.  Still, we
     have a few emulator bugfixes and support for running nested
     fully-virtualized Xen guests (para-virtualized Xen guests have
     always worked).  And some optimizations too.

  The only missing architecture here is ia64.  It's not a coincidence
  that support for KVM on ia64 is scheduled for removal in 3.17"

  time around.

  Returning to what is here this time...  we have 3 patches which fix
  various warnings.  Two are bug fixes (for quotas and also a rare
  recovery race condition).  The final patch, from Ben Marzinski, is an
  important change in the freeze code which has been in progress for
  some time.  This removes the need to take and drop the transaction
  lock for every single transaction, when the only time it was used, was
  at file system freeze time.  Ben's patch integrates the freeze
  operation into the journal flush code as an alternative with lower
  overheads and also lands up resolving some difficult to fix races at
  the same time"

 "For this release SPI has been exceptionally quiet, all the work has
  been on improving drivers (including taking advantage of some of the
  recent framework updates):

   - DMA support for the rspi driver providing a nice performance boost
   - performance improvement for the SIRF controller in PIO mode
   - new support for the Cadence SPI IP and for pxa2xx on BayTrail"

Pull pin control changes from Linus Walleij:
 "This is the bulk of pin control changes for the v3.16 development
  cycle:

   - Antoine Tenart made the get_group_pins() vtable entry optional.

   - Antoine also provides an entirely new driver for the Marvell Berlin
     SoC.  This is unrelated to the existing MVEBU hardware driver and
     warrants its own separate driver.

   - reflected from the GPIO subsystem there is a number of refactorings
     to make pin control drivers with gpiochips use the new gpiolib
     irqchip helpers.  The following drivers were converted to use the
     new infrastructure:
       * ST Microelectronics STiH416 and friends
       * The Atmel AT91
       * The CSR SiRF (Prima2)
       * The Qualcomm MSM series

   - massive improvements in the Qualcomm MSM driver from Bjorn
     Andersson, Andy Gross and Kumar Gala.  Among those new support for
     the IPQ8064 and MSM8x74 SoC variants.

   - support for the Freescale i.MX6 SoloX SoC variant.

   - massive improvements in the Allwinner sunxi driver from Boris
     Brezillon, Maxime Ripard and Chen-Yu Tsai.

   - Renesas PFC updates from Laurent Pinchart, Kuninori Morimoto,
     Wolfram Sang and Magnus Damm.

   - Cleanups and refactorings of the nVidia Tegra driver from Stepgen
     Warren.

   - the Exynos driver now supports the Exynos3250 SoC.

   - Intel BayTrail updates from Jin Yao, Mika Westerberg.

   - the MVEBU driver now supports the Orion5x SoC variants, which is
     part of the effort of getting rid of the old Marvell kludges in
     arch/arm/mach-orion5x

   - Rockchip driver updates from Heiko Stuebner.

   - a ton of cleanups and janitorial patches from Axel Lin.

   - some minor fixes and improvements here and there"

Pull first set of s390 updates from Martin Schwidefsky:
 "The biggest change in this patchset is conversion from the bootmem
  bitmaps to the memblock code.  This conversion requires two common
  code patches to introduce the 'physmem' memblock list.

  We experimented with ticket spinlocks but in the end decided against
  them as they perform poorly on virtualized systems.  But the spinlock
  cleanup and some small improvements are included.

  The uaccess code got another optimization, the get_user/put_user calls
  are now inline again for kernel compiles targeted at z10 or newer
  machines.  This makes the text segment shorter and the code gets a
  little bit faster.

  And as always some bug fixes"

Pull USB driver updates from Greg KH:
 "Here is the big USB driver pull request for 3.16-rc1.

  Nothing huge here, but lots of little things in the USB core, and in
  lots of drivers.  Hopefully the USB power management will be work
  better now that it has been reworked to do per-port power control
  dynamically.  There's also a raft of gadget driver updates and fixes,
  CONFIG_USB_DEBUG is finally gone now that everything has been
  converted over to the dynamic debug inteface, the last hold-out
  drivers were cleaned up and the config option removed.  There were
  also other minor things all through the drivers/usb/ tree, the
  shortlog shows this pretty well.

  All have been in linux-next, including the very last patch, which came
  from linux-next to fix a build issue on some platforms"
