Having GPUOBJ and VM intertwined like this makes it *really* hard to
continue porting to the new driver architecture, split it out in
favour of requiring explit maps be the caller.
It's more flexible and obvious this way anyway...

Adds an extra layer of indirection to each register access, but it's not

These currently just call the existing ones in nouveau_drv.c, but will be

This commit provides most of the infrastructure to support a major overhaul
of Nouveau's internals coming in the following commits. This work aims to
take all the things we've learned over the last several years, and turn that
into a cleaner architecture that's more maintainable going forward.
RAMHT and MM bits of the new core have been left out for the moment, and
will be pulled in as I go through the process of porting the code to
become either subdev or engine modules.
There are several main goals I wanted to achieve through this work:
-- Reduce complexity
The goal here was to make each component of the driver as independent as
possible, which will ease maintainability and readability, and provide a
good base for resetting locked up GPU units in the future.
-- Better tracking of GPU units that are required at any given time
This is for future PM work, we'll be able to tell exactly what parts of the
GPU we need powered at any given point (etc).
-- Expose all available NVIDIA GPUs to the client
In order to support things such as multi-GPU channels, we want to be able
to expose all the NVIDIA GPUs to the client over a single file descriptor
so it can send a single push buffer to multiple GPUs.
-- Untangle the core hardware support code from the DRM implementation
This happened initially as an unexpected side-effect of developing the
initial core infrastructure in userspace, but it turned into a goal of
the whole project. Initial benefits will be the availablility of a
number of userspace tools and tests using the same code as the driver
itself, but will also be important as I look into some virtualisation
ideas.
v2: Ben Skeggs <bskeggs@redhat.com>
- fix duplicate assignments noticed by clang
- implement some forgotten yelling in error path
- ensure 64-bit engine mask is used everywhere
v3: Marcin Slusarz <marcin.slusarz@gmail.com>
- sparse fixes
- inline nv_printk into nv_assert to prevent recursive inlining issues
v4: Ben Skeggs <bskeggs@redhat.com>
- fixed minor memory leak on gpuobj destruction

Future work will be headed in the way of separating the policy supplied by
the nouveau drm module from the mechanisms provided by the driver core.
There will be a couple of major classes (subdev, engine) of driver modules
that have clearly defined tasks, and the further directory structure change
is to reflect this.
No code changes here whatsoever, aside from fixing up a couple of include
file pathnames.

Won't necessarily be a drm_mm_node in the future, and I can't think of any
good reason to not use the offset from the bo struct. There may have been
some reason once apon a time, but, separate commit just in case.

Fixes some unfortunate races on resume. The G84 version of the code doesn't
need this as "gpuobj"s are automagically suspended/resumed by the core code
whereas pinned buffer objects are not.

Pull CMA and DMA-mapping updates from Marek Szyprowski:
"This time the pull request is rather small, because the further
redesign patches were not ready on time.
This pull request consists of the patches which extend ARM DMA-mapping
subsystem with support for CPU coherent (ACP) DMA busses. The first
client of the new version is HighBank SATA driver. The second part of
the pull request includes various cleanup for both CMA common code and
ARM DMA-mapping subsystem."

being added next to the "calxeda,port-phys" property for the Calxeda
AHCI controller.

This function is used by sparc, powerpc and arm64 for compat support.
The patch adds a generic implementation which calls do_sendfile()
directly and avoids set_fs().
The sparc architecture has wrappers for the sign extensions while
powerpc relies on the compiler to do the this. The patch adds wrappers
for powerpc to handle the u32->int type conversion.
compat_sys_sendfile64() can be replaced by a sys_sendfile() call since
compat_loff_t has the same size as off_t on a 64-bit system.
On powerpc, the patch also changes the 64-bit sendfile call from
sys_sendile64 to sys_sendfile.

There's no reason to call rcu_barrier() on every
deactivate_locked_super(). We only need to make sure that all delayed rcu
free inodes are flushed before we destroy related cache.
Removing rcu_barrier() from deactivate_locked_super() affects some fast
paths. E.g. on my machine exit_group() of a last process in IPC
namespace takes 0.07538s. rcu_barrier() takes 0.05188s of that time.

- Reworked PLL handing in the display code allows lots more

This also allows us to power down extra PLLs when we can
share a single one across multiple displays which saves power.

ARM: ux500: 8500: use hsit_a_2 group for HSI
pinctrl: use kasprintf() in pinmux_request_gpio()
pinctrl: pinctrl-single: Add pinctrl-single,bits type of mux
pinctrl/nomadik : add MC1_a_2 pin MC1 function group list
pinctrl: pinctrl-single: Make sure we do not change bits outside of mask

Pull GPIO changes from Linus Walleij:
"So this is the LW GPIO patch stack for v3.7:
- refactoring from Thierry Redding at Arnd Bergmann's request to use
the seq_file iterator interface in gpiolib.
- A new driver for Avionic Design's N-bit GPIO expander.
- Two instances of mutexes replaced by spinlocks from Axel Lin to
code that is supposed to be fastpath compliant.
- IRQ demuxer and gpio_to_irq() support for pcf857x by Kuninori
Morimoto.
- Dynamic GPIO numbers, device tree support, daisy chaining and some
other fixes for the 74x164 driver by Maxime Ripard.
- IRQ domain and device tree support for the tc3589x driver by Lee
Jones.
- Some conversion to use managed resources devm_* code.
- Some instances of clk_prepare() or clk_prepare_enable() added to
support the new, stricter common clock framework.
- Some for_each_set_bit() simplifications.
- Then a lot of fixes as we fixed up all of the above tripping over
our own shoelaces and that kind of thing."
