Sami Kiminki	5d09c908b0	gpu: nvgpu: Direct GMMU PTE kind control ... Allow userspace to control directly the PTE kind for the mappings by supplying NVGPU_AS_MAP_BUFFER_FLAGS_DIRECT_KIND_CTRL for MAP_BUFFER_EX. In particular, in this mode, the userspace will tell the kernel whether the kind is compressible, and if so, what is the incompressible fallback kind. By supplying only the compressible kind, the userspace can require that the map kind will not be demoted to the incompressible fallback kind in case of comptag allocation failure. Add also a GPU characteristics flag NVGPU_GPU_FLAGS_SUPPORT_MAP_DIRECT_KIND_CTRL to signal whether direct kind control is supported. Fix indentation of nvgpu_as_map_buffer_ex_args header comment.

Terje Bergstrom	c37c9baae6	gpu: nvgpu: Move CDE code to Linux module ... CDE is only used in Linux platforms, and the code is highly dependent on Linux APIs. Move the common CDE code to Linux module and leave only the chip specific parts to HAL.
