As a side note.. It's a bit hard to figure out how to name this commit..
GK20A is NVEA, which is before NV108 (GK208).. Confusing.

As documented at:
ftp://download.nvidia.com/open-gpu-doc/gk104-disable-graphics-power-gating/1/gk104-disable-graphics-power-gating.txt
NVIDIA were not able document the steps necessary to detect whether this
is required or not at this time. However, they did confirm that this
procedure is safe to perform unconditionally on GK104/6. GK107 does not
have the power gating feature, and it was recommended that we do not
perform these steps there as the effects were not verified.
The disable path is from observing the binary driver, and not
documented in the link above.

Due to recent consolidation of Exynos suspend and cpuidle code, some
parts of suspend and resume sequences are executed two times, once from
exynos_pm_syscore_ops and then from exynos_cpu_pm_notifier() and thus it
breaks suspend, at least on Exynos4-based boards. In addition, simple
core power down from a cpuidle driver could, in case of CPU 0 could
result in calling functions that are specific to suspend and deeper idle
states.
This patch fixes the issue by moving those operations outside the CPU PM
notifier into suspend and AFTR code paths. This leads to a bit of code
duplication, but allows additional code simplification, so in the end
more code is removed than added.

Pull GPIO update from Linus Walleij:
"This is the bulk of GPIO changes for the v3.17 development cycle, and
this time we got a lot of action going on and it will continue:
- The core GPIO library implementation has been split up in three
different files:
- gpiolib.c for the latest and greatest and shiny GPIO library code
using GPIO descriptors only
- gpiolib-legacy.c for the old integer number space API that we are
phasing out gradually
- gpiolib-sysfs.c for the sysfs interface that we are not entirely
happy with, but has to live on for ABI compatibility
- Add a flags argument to *gpiod_get* functions, with some
backward-compatibility macros to ease transitions. We should have
had the flags there from the beginning it seems, now we need to
clean up the mess. There is a plan on how to move forward here
devised by Alexandre Courbot and Mark Brown
- Split off a special <linux/gpio/machine.h> header for the board
gpio table registration, as per example from the regulator
subsystem
- Start to kill off the return value from gpiochip_remove() by
removing the __must_check attribute and removing all checks inside
the drivers/gpio directory. The rationale is: well what were we
supposed to do if there is an error code? Not much: print an error
message. And gpiolib already does that. So make this function
return void eventually
- Some cleanups of hairy gpiolib code, make some functions not to be
used outside the library private and make sure they are not
exported, remove gpiod_lock/unlock_as_irq() as the existing
function is for driver-internal use and fine as it is, delete
gpio_ensure_requested() as it is not meaningful anymore
- Support the GPIOF_ACTIVE_LOW flag from gpio_request_one() function
calls, which is logical since this is already supported when
referencing GPIOs from e.g. device trees
- Switch STMPE, intel-mid, lynxpoint and ACPI (!) to use the gpiolib
irqchip helpers cutting down on GPIO irqchip boilerplate a bit more
- New driver for the Zynq GPIO block
- The usual incremental improvements around a bunch of drivers
- Janitorial syntactic and semantic cleanups by Jingoo Han, and
Rickard Strandqvist especially"

Having no license specification in a module taints the kernel during load
with:
arm_big_little: module license 'unspecified' taints kernel.
and also the linker doesn't allow it to make use of GPL-exported symbols
which in this case also results in errors like:
arm_big_little: Unknown symbol cpufreq_register_driver (err 0)
. The header of the driver specifies a GPL v2 license, so note that
accordingly. While at it also add a description and an author and fix
the license in a companion file to explicit v2.

This patch does two things. It passes EFI run time mappings to second
kernel in bootparams efi_info. Second kernel parse this info and create
new mappings in second kernel. That means mappings in first and second
kernel will be same. This paves the way to enable EFI in kexec kernel.
This patch also prepares and passes EFI setup data through bootparams.
This contains bunch of information about various tables and their
addresses.
These information gathering and passing has been written along the lines
of what current kexec-tools is doing to make kexec work with UEFI.

Rework Tsi721 RapidIO DMA engine support to allow handling data
scatter/gather lists longer than number of hardware buffer descriptors in
the DMA channel's descriptor list.
The current implementation of Tsi721 DMA transfers requires that number of
entries in a scatter/gather list provided by a caller of
dmaengine_prep_rio_sg() should not exceed number of allocated hardware
buffer descriptors.
This patch removes the limitation by processing long scatter/gather lists
by sections that can be transferred using hardware descriptor ring of
configured size. It also introduces a module parameter
"dma_desc_per_channel" to allow run-time configuration of Tsi721 hardware
buffer descriptor rings.

Add RapidIO DMA interface routines that directly use reference to the mport
device object and/or target device destination ID as parameters.
This allows to perform RapidIO DMA transfer requests by modules that do not
have an access to the RapidIO device list.

The interrupt handler gets the driver data associated with the RTC
device and doesn't check it for validity. This can cause a NULL pointer
being dereferenced when and interrupt fires before the driver data was
properly set up.
Fix this by setting the driver data earlier (before the interrupt is
requested).

In rtc_suspend() and rtc_resume(), the error after rtc_read_time() is not
checked. If rtc device fail to read time, we cannot guarantee the
following process.
Add the verification code for returned rtc_read_time() error.

Add support for configuring the ISL12022 real-time clock via the Device
tree framework. This is based on what I've seen in the related ISL12057
driver, it has been tested and works on a Technologic Systems TS-7670
device which uses a ISL12020 RTC device, my device tree looks like this:
apbx@80040000 {
i2c0: i2c@80058000 {
pinctrl-names = "default";
pinctrl-0 = <&i2c0_pins_a>;
clock-frequency = <400000>;
status = "okay";
isl12022@0x6f {
compatible = "isl,isl12022";
reg = <0x6f>;
};
};
... etc
};
