[PATCH 0/2] GEM CMA DMA-BUF support

Hello,

This two patches add support for GEM CMA objects import and export as dma-buf
file handles.

There's not much to be added about the patches themselves, they're pretty
self-explicit. The code is based on the Exynos DRM DMA-BUF implementation.

The exporter role has been successfully tested with the Renesas R-Car DU
driver.
