Merge branch 'drm-prime-vmap' of git://people.freedesktop.org/~airlied/linux
Pull drm prime mmap/vmap code from Dave Airlie:
"As mentioned previously these are the extra bits of drm that relied on
the dma-buf pull to work, the first three just stub out the mmap
interface, and the next set provide vmap export to i915/radeon/nouveau
and vmap import to udl."
* 'drm-prime-vmap' of git://people.freedesktop.org/~airlied/linux:
radeon: add radeon prime vmap support.
nouveau: add vmap support to nouveau prime support
udl: support vmapping imported dma-bufs
i915: add dma-buf vmap support for exporting vmapped buffer
radeon: add stub dma-buf mmap functionality
nouveau: add stub dma-buf mmap functionality.
i915: add stub dma-buf mmap callback.
