How does the patch below look? 8<------- Allocate and copy all kernel memory before doing reservations. This prevents a locking inversion between mmap_sem and reservation_class, and allows us to drop the trylocking in ttm_bo_vm_fault without upsetting lockdep.

There is a lot of cleanup as well, and the drivers can now be properly unloaded and reloaded. HDMI support for the Tegra114 SoC was contributed by Mikko Perttunen. gr2d support was extended to Tegra114 and the gr3d driver that has been in the works for quite some time finally made it in. All pieces to run an OpenGL driver on top of an upstream kernel are now available. Support for syncpoint bases was added by Arto Merilainen. This is useful for synchronizing between command streams from different engines such as gr2d and gr3d. Erik Faye-Lund and Wei Yongjun contributed various small fixes.
