6c6ae061b6 drm/nouveau/fifo: allow direct access to channel control registers where possible
The indirect method has been left in-place here as a fallback path, as
it may not be possible to map the non-PAGE_SIZE aligned control areas
across some chipset+interface combinations.

This isn't a problem for the primary use-case where the core and drm
are linked together in kernel-land, but across a VM or (in the case
where it applies now) between the core in the kernel and a userspace
test tool.

and is also used by various userspace (either by a libdrm backend, or

8ec2a6ec6e drm/nouveau/core: import ioctl/event interfaces
This forms the basis for the new APIs that will be exposed to userspace,
giving it access to:

- Object method calls, the immediately useful of which is performance
  counters and the abiity to manipulate the ZBC tables.
- Information on the child classes an object supports, in order to avoid
  having to try all supported classes until successful.
- Notifications, which will be used in the future to inform the client
  if its channel was killed due to a lockup, etc.

This commit imports the interfaces, but are not currently used.  The DRM
portion of the driver will be ported to speak to the core using these
interfaces as much as possible.

79ca27706a drm/nouveau/core: rework event interface
This is a lot of prep-work for being able to send event notifications
back to userspace.  Events now contain data, rather than a "something
just happened" signal.

Handler data is now embedded into a containing structure, rather than
being kmalloc()'d, and can optionally have the notify routine handled
in a workqueue.

Various races between suspend/unload with display HPD/DP IRQ handlers
automagically solved as a result.

7820e5eef0 drm/nouveau: Bump version from 1.1.1 to 1.1.2
Linux 3.16 fixed multiple bugs in kms pageflip completion events
and timestamping, which were originally introduced in Linux 3.13.

These fixes have been backported to all stable kernels since 3.13.

However, the userspace nouveau-ddx needs to be aware if it is
running on a kernel on which these bugs are fixed, or not.

Bump the patchlevel of the drm driver version to signal this,
so backporting this patch to stable 3.13+ kernels will give the
ddx the required info.

9cba5efab5 drm/nouveau: Dis/Enable vblank irqs during suspend/resume.
Vblank irqs don't get disabled during suspend or driver
unload, which causes irq delivery after "suspend" or
driver unload, at least until the gpu is powered off.
This could race with drm_vblank_cleanup() in the case
of nouveau and cause a use-after-free bug if the driver
is unloaded.

More annoyingly during everyday use, at least on nv50
display engine (likely also others), vblank irqs are
off after a resume from suspend, but the drm doesn't
know this, so all vblank related functionality is dead
after a resume. E.g., all windowed OpenGL clients will
hang at swapbuffers time, as well as many fullscreen
clients in many cases. This makes suspend/resume useless
if one wants to use any OpenGL apps after the resume.

In Linux 3.16, drm_vblank_on() was added, complementing
the older drm_vblank_off()  to solve these problems
elegantly, so use those calls in nouveaus suspend/resume
code.

For kernels 3.8 - 3.15, we need to cherry-pick the
drm_vblank_on() patch to support this patch.
