	    uvm_pdaemon.c

Log Message:
fix locking for loaning.  in general we should be looking at the page's
uobject and uanon pointers rather than at the PQ_ANON flag to determine
which lock to hold, since PQ_ANON can be clear even when the anon's lock
is the one which we should hold (if the page was loaned from an object
and then freed by the object).
