SVN rev 207306 on 2010-04-28 04:57:32Z by alc
Change vm_object_madvise() so that it checks whether the page is invalid
or unmanaged before acquiring the page queues lock. Neither of these
tests require that lock. Moreover, a better way of testing if the page
is unmanaged is to test the type of vm object. This avoids a pointless
vm_page_lookup().
