This series adds helper functions that abstract the core parts of .gem_prime_import and .gem_prime_export so that drivers don't have to worry about the low-level details. These helpers are optional. A driver can use them by plugging in drm_gem_prime_import and drm_gem_prime_export into the drm_driver structure, or it can bypass them by plugging in its own functions. The first patch adds these helpers, and the later patches switch three drivers over to using them. This version of the series addresses concerns raised by Daniel Vetter, and to leave the vmap locking and refcounting to the dma-buf core code. It also drops Exynos from the series since its driver diverged between when I first sent out this series and now.
