v2: Introduces a TTM documentation change to clarify the discussion that
happened after the first version of this series was sent.
Also, removing pointless "unlikely" in the "Introduce a new placement for
MOB page tables" commit that Thomas noticed.

This is a largely trivial set that makes vmwgfx support module reload
and PCI hot-unplug. It also makes IGT's core_hotunplug pass instead
of kernel oops'ing.
