We have another version of it implemented in SW, however, that version
isn't serialised with normal PGRAPH operation and can possibly clobber
the enables for another context.
This is the same method that's implemented by the NVIDIA binary driver.

... and hope that the defaults are good enough. This was always
supposed to be a read/modify/write thing anyway, so we're writing
very wrong stuff for some boards already.

Should be the same values as before, except:
GF117 has smaller buffer allocated, as per register setup.
GK20A now uses values from Tegra driver, not GK104's.

Removes need for fixed buffer indices, and allows the functions
utilising them to also be run outside of context generation.

Default ZBC table is compatible with binary driver defaults.
Userspace will need to be updated to take full advantage of this
feature, however, some applications will see a performance boost
without updated drivers.

The full object interfaces are about to be exposed to userspace, so we
need to check for any security-related issues and version the structs
to make it easier to handle any changes we may need in the future.

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.

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.

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.
