9f403603f2 drm/nv40/pm: parse geometric delta clock from vbios 
This changes the meaning of what we reported as "core" clock previously.

The shader/rop units are allegedly supposed to be run at the base clock
listed in the perf table, while the geometric clock can be bumped from
this value on some boards.

So that we can report both, we'll report the base clock as "shader" (since
the shaders *do* run at it), and the geometric clock as "core".

91a8f1ea4b drm/nouveau: workaround semaphore hw bug causing unnecessary interrupts 
The HW will only accept the DMA_FROM_MEMORY class for DMA_SEMAPHORE without
asking the driver to intervene.

It appears that semaphores will work correctly even without DMA_IN_MEMORY,
so lets avoid the large amount of interrupts generated by x-chan sync.

658e86ee2d drm/nouveau: enable hwmon support when both nouveau/hwmon are built as modules. 
The nouveau hwmon temperature support currently only functions when hwmon is
compiled into the kernel. There's no reason why this shouldn't also work when
both hwmon and nouveau are modularised (as is the case with Slackware's stock
kernels).

VBIOS does more than this, as does nv50/nvc0 driver in nouveau.  Traces
of the NVIDIA binary driver however, show pretty much just this being
