0132605039 drm/nouveau/core/object: allow arguments to be passed to map function
MMU will be needing this to specify kind info on BAR mappings.

We have no userspace currently using these interfaces, so break the ABI
instead of supporting both.  NVIF version bump so any future use can be
guarded.

0f3804360d drm/nouveau/pm: allow to configure domains instead of simple counters
Configuring counters from the userspace require the kernel to handle some
logic related to performance counters. Basically, it has to find a free
slot to assign a counter, to handle extra counting modes like B4/B6 and it
must return and error when it can't configure a counter.

In my opinion, the kernel should not handle all of that logic but it
should only write the configuration sent by the userspace without
checking anything. In other words, it should overwrite the configuration
even if it's already counting and do not return any errors.

This patch allows the userspace to configure a domain instead of
separate counters. This has the advantage to move all of the logic to
the userspace.

5a0bc4b5ae drm/nouveau/pm: reorganize the nvif interface
This commit introduces the NVIF_IOCTL_NEW_V0_PERFMON class which will be
used in order to query domains, signals and sources. This separates the
querying and the counting interface.

c39f472e9f drm/nouveau: remove symlinks, move core/ to nvkm/ (no code changes)
The symlinks were annoying some people, and they're not used anywhere
else in the kernel tree.  The include directory structure has been
changed so that symlinks aren't needed anymore.

NVKM has been moved from core/ to nvkm/ to make it more obvious as to
what the directory is for, and as some minor prep for when NVKM gets
split out into its own module (virt) at a later date.
