Due to the GPU preventing us from touching NV_PLTCG_LTCS_LTSS_CBC_BASE,
we cannot provide CBC/ZBC support without signed PMU firmware to handle

4cb53a5ed1 drm/nouveau/mmu/gp100: initial support 
GP100 still supports the previous generations' page table layout, which
we will temporarily make use of here.

Proper support for the new MMU layout requires some rework to the common
MMU code, which is in progress.

539aae6e3a drm/nouveau/Revert "drm/nouveau/device/pci: set as non-CPU-coherent on ARM64" 
This reverts commit 1733a2ad36.

There is apparently something amiss with the way the TTM code handles
DMA buffers, which the above commit was attempting to work around for
arm64 systems with non-coherent PCI. Unfortunately, this completely
breaks systems *with* coherent PCI (which appear to be the majority).

Booting a plain arm64 defconfig + CONFIG_DRM + CONFIG_DRM_NOUVEAU on
a machine with a PCI GPU having coherent dma_map_ops (in this case a
7600GT card plugged into an ARM Juno board) results in a fatal crash:

[    2.898888] Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b

In a toss-up between the GPU seeing stale data artefacts on some systems
vs. catastrophic kernel crashes on other systems, the latter would seem
to take precedence, so revert this change until the real underlying
problem can be fixed.

a8953c52b9 drm/nouveau/disp/sor/gf119: both links use the same training register 
It appears that, for whatever reason, both link A and B use the same
register to control the training pattern.  It's a little odd, as the
GPUs before this (Tesla/Fermi1) have per-link registers, as do newer
GPUs (Maxwell).

Fixes the third DP output on NVS 510 (GK107).

This drops the NVKM_ENGINE_FIFO data from the entries too, as resetting
all of PFIFO is *not* the way to handle such faults.

86d65b7e7a nouveau: fix nv40_perfctr_next() cleanup regression 
gcc-6 warns about code in the nouveau driver that is obviously silly:

drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c: In function 'nv40_perfctr_next':
drivers/gpu/drm/nouveau/nvkm/engine/pm/nv40.c:62:19: warning: self-comparison always evaluats to false [-Wtautological-compare]
  if (pm->sequence != pm->sequence) {

The behavior was accidentally introduced in a patch described as "This is
purely preparation for upcoming commits, there should be no code changes here.".
As far as I can tell, that was true for the rest of that patch except for
this one function, which has been changed to a NOP.

This patch restores the original behavior.

This class supports a WFI method (0x0078) that's not present on the
KeplerChannelGpfifoA class.

The binary driver exposes both classes on these GPUs for some reason,
though there doesn't appear to be any difference in the setup that's
done for each (ie. even if you allocate GpfifoA, the WFI method will
still work).

We shall just expose GpfifoB, as I don't see a good reason to report
the presence of both.
