[PATCH v3.18-rc3] drm: msm: Allow exported dma-bufs to be mapped

2014-11-10 Thread Daniel Thompson
Currently msm does not implement gem_prime_mmap. Without this it is not possible to draw onto a dma-buf from another process (making its very hard to implement the Android rendering model). Implementing this mostly just providing some boilerplate code. However in addition to providing the implemen
