From: Chris Wilson <ch...@chris-wilson.co.uk>
As our contexts are more general than the logical contexts supported by
the hardware, for instance they allow per context hangcheck tracking, it
is beneficial to group tasks across rings belonging to the same context.
Context switching is already a no-op for unsupported rings, we just
suffered from a little too overzealous parameter checking on entry - now
we just check that the context is valid.
