pk d114baba9a Introduce vm_object_prefer(), which interrogates the PMAP layer in search
for an optimal virtual address for a given object.

cgd aa151f86b3 change some strategic casts to (*long) from (*int). 1994-10-29 07:35:04 +00:00
mycroft 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.

call vm_object_remove() to remove an object from the hashtable when
vm_object_collapse() starts fiddling with pagers.

andrew 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.

cgd 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.
