Log Message:
Pull up following revision(s) (requested by riastradh in ticket #46):
        sys/external/bsd/drm2/dist/drm/i915/i915_gem.c: revision 1.15
        sys/external/bsd/drm2/ttm/ttm_bo_vm.c: revision 1.4
Do not take the {ttm,gem} vmobjlock in the fault handler.
- We don't need this lock.
- uvm does nothing between taking it and calling the fault handler.
- Now that the uvm_aobj shares vmobjlock with the {ttm,gem} uvm
  object, we must not hold the lock when we call uvm_obj_wirepages on
  the uvm_aobj.
