Are you going to be OK with kernel API which implements contiguous
memory allocation?  Possibly with mmap style?  Many drivers could
utilize it instead of having their own weird and possibly non-standard
way to allocate contiguous memory.  Such API won't be available for
user space.

What you describe sounds like CMA.  It may be far from perfect but it’s
there already and drivers which need contiguous memory can allocate it.
