Add support for running a msgqueue on the SEC2 falcon.

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
On SEC, DMEM is unaccessible by the CPU when the falcon is running in LS
mode. This makes communication with the firmware using DMEM impossible.
For this purpose, a new kind of memory (EMEM) has been added. It works
similarly to DMEM, with the difference that its address space starts at
0x1000000. For this reason, it makes sense to treat it like a special
case of DMEM.

Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
A message queue firmware implements a specific protocol allowing the
host to send "commands" to a falcon, and the falcon to reply using
"messages". This patch implements the common part of this protocol and
defines the interface that the host can use.
Due to the way the firmware is developped internally at NVIDIA (where
kernel driver and firmware evolve in lockstep), firmwares taken at
different points in time can have frustratingly subtle differences that
must be taken into account. This code is architectured to make
implementing such differences as easy as possible.

Ideally we'd be able to keep these at a more obvious error level, as
they're a good indication of us doing something wrong.
However, NVIDIA's FECS/GPCCS firmware touches registers that trigger
priv ring faults, and we can't do anything to fix that ourselves due
to the need for them to be signed by NVIDIA.
This issue was reported a while back, but hasn't been fixed, so, for
now we will hide the messages to prevent spamming Optimus users with
messages whenever the NVIDIA GPU is powered off and on again.

Misc fixes for the 4.11 merge window.
- vmwgfx drm_control node compat patch
- rockchip&zte fix
- compat32 support for dma-buf ioctl (cc: stable ofc, since this is a
massive fumble. oops)

drm/vmwgfx: Work around drm removal of control nodes
drm/rockchip: cdn-dp: Fix error handling
drm/rockchip: add extcon dependency for DP
drm: zte: fix static checker warning on variable 'fmt'
vmware tools has a daemon that gets layout information from the GUI and
forwards it to DRM so that the modesetting code can set preferred connector
locations and modes. This daemon was using control nodes but since control
nodes were just removed, make it possible for the daemon to use render- or
primary nodes instead. This is a bit ugly but will allow drm to proceed with
removal of the mostly unused control-node code and allow vmware to proceed
with fixing up automatic layout settings for gnome-shell/wayland.
We bump minor to inform user-space about the api change.

Merge tag 'drm-for-v4.11-less-shouty' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"This is the main drm pull request for v4.11.
Nothing too major, the tinydrm and mmu-less support should make
writing smaller drivers easier for some of the simpler platforms, and
there are a bunch of documentation updates.
Intel grew displayport MST audio support which is hopefully useful to
people, and FBC is on by default for GEN9+ (so people know where to
look for regressions). AMDGPU has a lot of fixes that would like new
firmware files installed for some GPUs.
Other than that it's pretty scattered all over.
I may have a follow up pull request as I know BenH has a bunch of AST
rework and fixes and I'd like to get those in once they've been tested
