[PATCH 0/5] drm/vmwgfx: Support module unload and hotunplug

[Zack Rusin <zackr@vmware.com>]

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.

The one "ugly" change is the "Introduce a new placement for MOB page
tables". It seems vmwgfx has been violating a TTM assumption that
TTM_PL_SYSTEM buffers are never fenced for a while. Apart from a kernel
oops on module unload it didn't seem to wreak too much havoc, but we
shouldn't be abusing TTM. So to solve it we're introducing a new
placement, which is basically system, but can deal with fenced bo's.
