* gpu: nvgpu: Control comptagline assignment from kernelTerje Bergstrom2016-01-05
| | | | | | | | | | | | | | | | | | | | | On Maxwell comptaglines are assigned per 128k, but preferred big page size for graphics is 64k. Bit 16 of GPU VA is used for determining which half of comptagline is used. This creates problems if user space wants to map a page multiple times and to arbitrary GPU VA. In one mapping the page might be mapped to lower half of 128k comptagline, and in another mapping the page might be mapped to upper half. Turn on mode where MSB of comptagline in PTE is used instead of bit 16 for determining the comptagline lower/upper half selection.

* gpu: nvgpu: Sync gk20a and gm20b headersTerje Bergstrom2015-03-18
| | | | | | | | | | | | | Synchronize gk20a and gm20b headers. All registers which were added to gk20a are now added to gm20b, and some registers that are unused are removed.
