        src/sys/external/bsd/drm2/dist/drm/i915: i915_gem.c
        src/sys/external/bsd/drm2/ttm: ttm_bo_vm.c

Log Message:
Drop 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.
