Add the callbacks necessary to implement emulated coherent memory for
surfaces. Add a flag to the gb_surface_create ioctl to indicate that
surface memory should be coherent.
Also bump the drm minor version to signal the availability of coherent
surfaces.

UAPI Changes:

- Make context persistence optional
  Allow userspace to tie the context lifetime to FD lifetime,
  effectively allowing Ctrl-C killing of a process to also clean
  up the hardware immediately.
  Compute changes: https://github.com/intel/compute-runtime/pull/228
  The compute driver is shipping in Ubuntu. uAPI acked by Mesa folks.

- Put future HW and their uAPIs under STAGING &amp; BROKEN
  Introduces DRM_I915_UNSTABLE Kconfig menu for working on the new
  uAPI for future HW in upstream. We already disable driver loading
  by default the platform is deemed ready. This is a second level
  of protection based on compile time switch (STAGING &amp; BROKEN).

- Under DRM_I915_UNSTABLE: Add the fake lmem region on iGFX
  Fake local memory region on integrated GPU through cmdline:
  memmap=2G$16G i915.fake_lmem_start=0x400000000
  Currently allows testing non-mappable GGTT behavior and running
  kernel selftest for local memory.

<title>drm/i915/gem: Make context persistence optional</title>

<id>a0e047156cdebbccf253768b39d7e1dbf954c449</id>
<content type='text'>
Our existing behaviour is to allow contexts and their GPU requests to
persist past the point of closure until the requests are complete. This
allows clients to operate in a 'fire-and-forget' manner where they can
setup a rendering pipeline and hand it over to the display server and
immediately exit. As the rendering pipeline is kept alive until
completion, the display server (or other consumer) can use the results
in the future and present them to the user.

The compute model is a little different. They have little to no buffer
sharing between processes as their kernels tend to operate on a
continuous stream, feeding the results back to the client application.
These kernels operate for an indeterminate length of time, with many
clients wishing that the kernel was always running for as long as they
keep feeding in the data, i.e. acting like a DSP.

Not all clients want this persistent "desktop" behaviour and would prefer
that the contexts are cleaned up immediately upon closure. This ensures
that when clients are run without hangchecking (e.g. for compute kernels
of indeterminate runtime), any GPU hang or other unexpected workloads
are terminated with the process and does not continue to hog resources.

The default behaviour for new contexts is the legacy persistence mode,
as some desktop applications are dependent upon the existing behaviour.
New clients will have to opt in to immediate cleanup on context
closure. If the hangchecking modparam is disabled, so is persistent
context support -- all contexts will be terminated on closure.

We expect this behaviour change to be welcomed by compute users, who
have often been caught between a rock and a hard place. They disable
hangchecking to avoid their kernels being "unfairly" declared hung, but
have also experienced true hangs that the system was then unable to
clean up. Naturally, this leads to bug reports.

This reverts commit 23b482252836ab3c5e6b3b20ed3038449cbc7679.

This patch does not have an acceptable open source userspace
implementation, and as such it does not meet the requirements for adding
new UAPI.

Discussion is in the Link.
