801712f01a Extend use of vm_object_prefer() to vm_allocate_with_pager(). 
Make vm_object_prefer() call MD aligner for "pageless" objects too,
so we can have more control over the virtual address to be used.

Implementation could be simpler if we by-pass the object to mapped, but
we'd loose the ability to adapt alignment to objects that were previously
mmap'ed with MAP_FIXED on.

6dd2f9eed2 vm_object_page_clean() expects to be able to use vm_page_deactivate() on a 
locked page.  Make that work.  This also obviates the need for vm_fault() to
bogusly activate a page before deactivating it.  Finally, make sure the
semantics of vm_object_deactive_pages() don't change.

7a0e26cd13 Paul Kranenburg's VM deadlock patches (from patchkit 00147, parts 3 & 4). 
Prevent dirty objects from being cached, and prevent vm_page_alloc() from
allocating too much memory to non-kernel objects.

827c75471f From: andrew@werple.apana.org.au (Andrew Herbert) 
Here are some fixes I derived from the mach 3.0 VM system a couple of months
ago.  At the time, I was giving the memory object routines a good looking
at, trying to fix the long-standing problem where vm_object_collapse()
sometimes fails to collapse objects left over from the exit of a forked
child.  As bde has noted, the problem seems to occur when portions of the
parent are paged out.  These "lost" memory objects, which can eat up a huge
amount of swap space, are reclaimed when the parent responsible for the
fork()s is killed.
