Subject: [PATCH] drm/gpuvm: Dual-licence the drm_gpuvm code GPL-2.0 OR MIT

Dual-licence in order to make it possible for other non-GPL os'es
to re-implement the code. The use of EXPORT_SYMBOL_GPL() is intentionally
left untouched to prevent use of drm_gpuvm as a proxy for non-GPL drivers
to access GPL-only kernel symbols.

Much of the ideas and algorithms used in the drm_gpuvm code is already
present in one way or another in MIT-licensed code.
