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. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
