Sagar Kamble	7e7d36f8e5	gpu: nvgpu: define uapi for register buffer ioctl ... To enable userspace query about comptags allocation status of a buffer, comptags are to be allocated only during buffer allocation through nvrm_gpu. Further, other metadata can be associated with the buffer during allocation. Define a new ioctl NVGPU_GPU_IOCTL_REGISTER_BUFFER and related input struct for this purpose. Define GPU characteristics flag to indicate support of buffer metadata.

Alex Waterman	a4dc48061c	gpu: nvgpu: Begin splitting IOCTL header ... The end goal is to split all of the different IOCTLs into different headers. This should make it a bit easier to work with these IOCTL headers.
