KVM: s390: features and fixes for 4.9
- lazy enablement of runtime instrumentation
- up to 255 CPUs for nested guests
- rework of machine check deliver
- cleanups/fixes
The GR8 is an SoC made by Nextthing Co, loosely based on the sun5i family.
It has a number of new controllers compared to the A10s and A13 (SPDIF, I2S),
but some controllers missing too (Ethernet, less I2C, less UARTs).

redistributor, and CPU interface registers for GICv3 in this new file,
and add a group for accessing level triggered IRQ information for GICv3
as well.

In order to support capture of PWM signals a new clock as well as an
interrupt line are required. Furthermore a new property is introduced
that allows the number of capture channels to be specified. Typically
there will be less capture channels than output channels, since all
channels have the latter capability, but only some have support for
capture.

The A33 pipeline also has a component called DRC. Even though its exact
features and programming model is not known (or documented), it needs to
be clocked for the pipeline to carry the video signal all the way.
Add a minimal driver for it that just claim the needed resources for the
pipeline to operate properly.

This adds device tree bindings for:
- An optional GPIO line for releasing the RESET signal to the
SMSC911x devices
- An optional PME (power management event) interrupt line that
can be utilized to wake up the system on network activity.
This signal exist on all the SMSC911x devices, it is just not
very often routed.
Both these lines are routed to the SoC on the Qualcomm APQ8060
Dragonboard and thus needs to be bound in the device tree.

Register ASoC HDMI codec for audio functionality and adds device tree
binding for audio configuration.
With the registered HDMI codec the tda998x node can be used like a
regular codec node in ASoC card configurations. HDMI audio info-frame
and audio stream header is generated by the ASoC HDMI codec. The codec
also applies constraints for available sample-rates based on Edid Like
Data from the display. The device tree binding document has been
updated [1].
Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x:
Add support of a DT graph of ports"-patch [2]. There may still be some
identical lines left from the original patch and some of the ideas
have come from there.

so extend the API to allow this rather than using the internal static

- The guide currently says to pad the structure to a multiple of
64-bits. This is not necessary in cases where the structure contains
no 64-bit types. Clarify this concept to avoid unnecessary padding.
- When using __u64 to hold user pointers, blindly trying to do a cast to
a void __user * may generate a warning on 32-bit systems about a cast
from an integer to a pointer of different size. There is a macro to
deal with this which hides an ugly double cast. Add a reference to
this macro.

The change corrects an example in device tree documentation section,
because button/key device nodes don't contain reg property there is
no need to declare unit-address, and address and size cell properties
are also redundant.
At the moment a compilation of the hypothetical original example
should produce W=1 level warnings, and it is better to stop spreading
misusage of the polled gpio keys device tree binding through this
example.
