gpu: nvgpu: Add nvgpu_os_buffer
Add a generic nvgpu_os_buffer type, defined by each OS, to abstract
a "user" buffer. This allows the comptag interface to be used in the
core code.
The end goal of this patch is to allow the OS specific mapping code
to call a generic mapping function that handles most of the mapping
logic. The problem is a lot of the logic involves comptags which are
highly dependent on the operating systems buffer management scheme.
With this, each OS can implement the buffer comptag mechanics
however it wishes without the core MM code caring.
