 Log Message:
 PR kern/55033: kernel panics when starting X
 
 Remove the uvm_page_owner_locked_p() assertions in the x86 pmap.  The DRM
 code doesn't follow the locking protocol (it's OK though, since pages aren't
 changing identity) and having thought about it more we're most likely going
 to have to do full PV locking to make progress on concurrent fault handing,
 ergo assertions not so important.
