* gpu: nvgpu: Implement 64k large page supportTerje Bergstrom2015-03-18
| | | | | | | | | | | | | | | Implement support for 64kB large page size. Add an API to create an address space via IOCTL so that we can accept flags, and assign one flag for enabling 64kB large page size. Also adds APIs to set per-context large page size. This is possible only on Maxwell, so return error if caller tries to set large page size on Kepler. Default large page size is still 128kB.

* gpu: nvgpu: create new nvgpu ioctl headerKonsta Holtta2015-03-18
Move nvgpu ioctls from the many user space interface headers to a new single nvgpu.h header under include/uapi. No new code or replaced names are introduced; this change only moves the definitions and changes include directives accordingly.
