Uncertain whether the GPC pack change is due to a newer driver version,
or a legitimate difference from GM204. My GM204 has broken vram, so
can't currently try a newer binary driver on it to confirm.

Under certain circumstances the trapped address will contain subc 7,
which GK104 GR doesn't have anymore.
Notice this case to avoid causing additional priv ring faults.

No idea if "3" is a constant or derived from something else, but the
value is unchanged in the limited traces of gm107/gm204 I have here.

On some of these chipsets, reading NV_PGRAPH_GPC_GPM_PD_PES_TPC_ID_MASK
can trigger a PRI fault and return an error code instead of a TPC mask,
unless PGOB has been disabled first.

Before we moved gk110's implementation of this to pmu, the functions were
identical. This commit just switches GK208 to use the new (more complete)
implementation of the power-up sequence.

Turns out the PTHERM part of this dance is bracketed by the same PMU
fiddling that occurs on GK104/6, let's assume it's also PGOB.

Notify interrupt is only used for cyclestats. We can just clear it and
avoid an "unknown stat" error that gets printed to dmesg otherwise.

Other methods in this file suggest this is the correct way to retrieve
the engine pointer.

The namespace of NVKM is being changed to nvkm_ instead of nouveau_,
which will be used for the DRM part of the driver. This is being
done in order to make it very clear as to what part of the driver a
given symbol belongs to, and as a minor step towards splitting the
DRM driver out to be able to stand on its own (for virt).
Because there's already a large amount of churn here anyway, this is
as good a time as any to also switch to NVIDIA's device and chipset
naming to ease collaboration with them.
A comparison of objdump disassemblies proves no code changes.
