SEC2 is the name given by NVIDIA to the SEC engine post-Fermi (reasons
unknown). Even though it shares the same address range as SEC, its usage
is quite different and this justifies a new engine. Add this engine and
make TOP use it all post-TOP devices should use this implementation and
not the older SEC.
Also quickly add the short gp102 implementation which will be used for
falcon booting purposes.

Reading registers at device construction time can be harmful, as there
is no guarantee the underlying engine will be up, or in its runtime
configuration. Defer register reading to the oneinit() hook and update
users accordingly.

Both registers allow to bind a new context, but NXTCTX will work on all
falcons, while legacy NEW_INSTBLK is reserved to PMU.
After setting NXTCTX we trigger a context switch by writing 0x090 and
0x0a4.

The ACR firmware may return no error but fail nonetheless. Such cases

PMU support has been enabled for r352 ACR, but it must remain optional
if we want to preserve existing user-space that do not include it. Allow
ACR to be instanciated with a list of optional LS falcons, that will not
produce a fatal error if their firmware is not loaded. Also change the
secure boot bootstrap logic to be able to fall back to legacy behavior
if it turns out the boot falcon's LS firmware cannot be loaded.

Adapt secboot's behavior if a PMU firmware is present, in particular
the way LS falcons are reset. Without PMU firmware, secboot needs to be
performed again from scratch so all LS falcons are reset. With PMU
firmware, we can ask the PMU's ACR unit to reset a specific falcon
through a PMU message.
As we must preserve the old behavior to avoid breaking user-space, add a
few conditionals to the way falcons are reset.

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.

git://anongit.freedesktop.org/git/drm-misc into drm-next
First slice of drm-misc-next for 4.12:
Core/subsystem-wide:
- link status core patch from Manasi, for signalling link train fail
to userspace. I also had the i915 patch in here, but that had a
small buglet in our CI, so reverted.
- more debugfs_remove removal from Noralf, almost there now (Noralf
said he'll try to follow up with the stragglers).
- drm todo moved into kerneldoc, for better visibility (see
Documentation/gpu/todo.rst), lots of starter tasks in there.
- devm_ of helpers + use it in sti (from Ben Gaignard, acked by Rob
Herring)
- extended framebuffer fbdev support (for fbdev flipping), and vblank
wait ioctl fbdev support (Maxime Ripard)
- misc small things all over, as usual
- add vblank callbacks to drm_crtc_funcs, plus make lots of good use
of this to simplify drivers (Shawn Guo)
- new atomic iterator macros to unconfuse old vs. new state
Small drivers:
- vc4 improvements from Eric
- vc4 kerneldocs (Eric)!
- tons of improvements for dw-mipi-dsi in rockchip from John Keeping
and Chris Zhong.
- MAINTAINERS entries for drivers managed in drm-misc. It's not yet
official, still an experiment, but definitely not complete fail and
better to avoid confusion. We kinda screwed that up with drm-misc a
bit when we started committers last year.
- qxl atomic conversion (Gabriel Krisman)
- bunch of virtual driver polish (qxl, virgl, ...)
- misc tiny patches all over
This is the first time we've done the same merge-window blackout for
drm-misc as we've done for drm-intel for ages, hence why we have a
_lot_ of stuff queued already. But it's still only half of drm-intel
(room to grow!), and the drivers in drm-misc experiment seems to work
at least insofar as that you also get lots of driver updates here
alredy.

Unbind the vma may happen at any time, outside of the normal GT wakeref.
As such it relies on having a wakeref of its own. However, we can forgo
clearing the register whilst the device is asleep and just mark it as
unused - so that when we do wake up the device, we will clear the unused
fence register (see i915_gem_restore_fences).

Instead of only complaining when we actually miss a vblank, always
complain if we take longer than 100 us. This will make it easier to
find cases where we potentially miss vblanks.

This cannot be done reliably during vblank evasasion
since the color management registers are not double buffered.
The original commit that moved it always during vblank evasion was
wrong, so revert it to before vblank evasion again.

Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Missing check for full sock in ip_route_me_harder(), from
Florian Westphal.
2) Incorrect sip helper structure initilization that breaks it when
several ports are used, from Christophe Leroy.
3) Fix incorrect assumption when looking up for matching with adjacent
intervals in the nft_set_rbtree.
4) Fix broken netlink event error reporting in nf_tables that results
in misleading ESRCH errors propagated to userspace listeners.

Pull libnvdimm fixes from Dan Williams:
"A fix and regression test case for nvdimm namespace label
compatibility.
Details:
- An "nvdimm namespace label" is metadata on an nvdimm that
provisions dimm capacity into a "namespace" that can host a block
device / dax-filesytem, or a device-dax character device.
A namespace is an object that other operating environment and
platform firmware needs to comprehend for capabilities like booting
from an nvdimm.
The label metadata contains a checksum that Linux was not
calculating correctly leading to other environments rejecting the
Linux label.
These have received a build success notification from the kbuild
robot, and a positive test result from Nick who reported the problem"
