IOMMU Updates for Linux v3.20

This time with:

	* Generic page-table framework for ARM IOMMUs using the LPAE page-table
	  format, ARM-SMMU and Renesas IPMMU make use of it already.

	* Break out of the IO virtual address allocator from the Intel IOMMU so
	  that it can be used by other DMA-API implementations too. The first
	  user will be the ARM64 common DMA-API implementation for IOMMUs

	* Device tree support for Renesas IPMMU

	* Various fixes and cleanups all over the place

Fairly small update, but there are some interesting new features.

Common: Optional support for adding a small amount of polling on each HLT
instruction executed in the guest (or equivalent for other architectures).
This can improve latency up to 50% on some scenarios (e.g. O_DSYNC writes
or TCP_RR netperf tests).  This also has to be enabled manually for now,
but the plan is to auto-tune this in the future.

ARM/ARM64: the highlights are support for GICv3 emulation and dirty page
tracking

s390: several optimizations and bugfixes.  Also a first: a feature
exposed by KVM (UUID and long guest name in /proc/sysinfo) before
it is available in IBM's hypervisor! :)

MIPS: Bugfixes.

x86: Support for PML (page modification logging, a new feature in
Broadwell Xeons that speeds up dirty page tracking), nested virtualization
improvements (nested APICv---a nice optimization), usual round of emulation
fixes.  There is also a new option to reduce latency of the TSC deadline
timer in the guest; this needs to be tuned manually.

Some commits are common between this pull and Catalin's; I see you
have already included his tree.

ARM has other conflicts where functions are added in the same place
by 3.19-rc and 3.20 patches.  These are not large though, and entirely
within KVM.

rtlwifi:

* remove superfluous warning message which is not needed anymore

This is the 3.18.7 stable release

This is the 3.14.33 stable release

This is the 3.10.69 stable release

This is the GPIO bulk changes for the v3.20 series:
- GPIOLIB core changes:
  - Create and use of_mm_gpiochip_remove() for removing
    memory-mapped OF GPIO chips
  - GPIO MMIO library suppports bgpio_set_multiple for
    switching several lines at once, a feature merged in
    the last cycle.
- New drivers:
  - New driver for the APM X-gene standby GPIO controller
  - New driver for the Fujitsu MB86S7x GPIO controller
- Cleanups:
  - Moved rcar driver to use gpiolib irqchip
  - Moxart converted to the GPIO MMIO library
  - GE driver converted to GPIO MMIO library
  - Move sx150x to irqdomain
  - Move max732x to irqdomain
  - Move vx855 to use managed resources
  - Move dwapb to use managed resources
  - Clean tc3589x from platform data
  - Clean stmpe driver to use device tree only probe
- New subtypes:
  - sx1506 support in the sx150x driver
  - Quark 1000 SoC support in the SCH driver
  - Support X86 in the Xilinx driver
  - Support PXA1928 in the PXA driver
- Extended drivers:
  - max732x supports device tree probe
  - sx150x supports device tree probe
- Various minor cleanups and bug fixes

media updates for v3.20-rc1

ASoC: Final updates for v3.20

A few more updates for v3.20 that have accumilated over the second half
of last week.  One new (relatively simple) driver for the Maxim
max98357a and some other driver specific fixes and enhancements.  I did
apply a few patches that haven't been in -next just now before sending
this, all fixes except for one simple device ID addition patch.

Linux 3.19

This is the 3.18.6 stable release

This is the 3.14.32 stable release

This is the 3.10.68 stable release

ASoC: Fix for Intel firmware name

Another one liner that arrived after the earlier pull request.  There's
a trivial conflict with my -next branch, I'll send a pull request with
that resolution and some other new stuff before Monday.

ASoC: AC'97 fixes

These are rather too large for this late in the release cycle but
they're clear, well understood and have been tested to fix a regression
which was introduced for v3.19.  The details are all in Lars' changelog
and they've been cooking in -next for a while, to a large extent out
of conservatism about the size.

ASoC: Fixes for v3.19

A few last minute fixes for v3.19, all driver specific.  None of them
stand out particularly - it's all the standard people who are affected
will care stuff.

The Samsung fix is a DT only fix for the audio controller, it's being
merged via the ASoC tree due to process messups (the submitter sent it
at the end of a tangentally related series rather than separately to the
ARM folks) in order to make sure that it gets to people sooner.

ASoC: Updates for v3.20

More updates for v3.20:

 - Lots of refactoring from Lars-Peter Clausen, moving drivers to more
   data driven initialization and rationalizing a lot of DAPM usage.
 - Much improved handling of CDCLK clocks on Samsung I2S controllers.
 - Lots of driver specific cleanups and feature improvements.
 - CODEC support for TI PCM514x and TLV320AIC3104 devices.
 - Board support for Tegra systems with Realtek RT5677.

Yet more GPIO fixes for the v3.19 series:
- Two fixes stabilizing that which was never stable before:
  removal of GPIO chips, now let's stop leaking memory.
- Make sure OMAP IRQs are usable when the irqchip API
  is used orthogonally to the gpiochip API.
- Provide a default GPIO base for the mcp23s08 driver.
