drm/nouveau/core: use vzalloc for allocating ramht Most calls to nvkm_ramht_new use 0x8000 as the size. This results in a fairly sizeable chunk of memory to be allocated, which may not be available with kzalloc. Since this is done fairly rarely (once per channel), use vzalloc instead.

drm/nouveau/bar: namespace + nvidia gpu names (no binary change) 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>

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.
