The hardware tracks contexts and expects all live contexts (those active on the hardware) to have a unique identifier. This is used by the hardware to assign pagefaults and the like to a particular context. v2: Reorder to make sure ctx->link is not left dangling if the assignment of a hw_id fails (Mika). v3: We have 21bits of context space, not 20.
