- CS ioctl cleanup and unification. Unification of a lot of functionality
that was duplicated across multiple generates of hardware.
- Add support for Oland GPUs
- Deprecate UMS support. Mesa and the ddx dropped support for UMS and
apparently very few people still use it since the UMS CS ioctl was broken
for several kernels and no one reported it. It was fixed in 3.8/stable.
- Rework GPU reset. Use the status registers to determine what blocks
to reset. This better matches the recommended reset programming model.
This also allows us to properly reset blocks besides GFX and DMA.
- Switch the VM set page code to use an IB rather than the ring. This
fixes overflow issues when doing large page table updates using a small
ring like DMA.
- Several small cleanups and bug fixes.
