7f0bf36a2e o Extend the scope of the page queues lock in contigmalloc1(). 
o Replace vm_page_sleep_busy() with vm_page_sleep_if_busy()
   in vm_contig_launder().

55df3298c6 o Require that the page queues lock is held on entry to vm_pageout_clean() 
and vm_pageout_flush().
 o Acquire the page queues lock before calling vm_pageout_clean()
   or vm_pageout_flush().

1d7cf06c8c o Use vm_map_wire() and vm_map_unwire() in place of vm_map_pageable() and 
vm_map_user_pageable().
 o Remove vm_map_pageable() and vm_map_user_pageable().
 o Remove vm_map_clear_recursive() and vm_map_set_recursive().  (They were
   only used by vm_map_pageable() and vm_map_user_pageable().)

b386828956 contigmalloc1() could cause the vm_page_zero_count to become incorrect. 
Properly track the count.

33bd457d91 Makes contigalloc[1]() create the vm_map / underlying wired pages in the 
kernel map and object in a manner that contigfree() is actually able to
free.  Previously contigfree() freed up the KVA space but could not
unwire & free the underlying VM pages due to mismatched pageability between
the map entry and the VM pages.

b40ce4165d KSE Milestone 2 
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

6d03d577a5 Reorg vm_page.c into vm_page.c, vm_pageq.c, and vm_contig.c (for contigmalloc). 
Also removed some spl's and added some VM mutexes, but they are not actually
used yet, so this commit does not really make any operational changes
to the system.

vm_page.c relates to vm_page_t manipulation, including high level deactivation,
activation, etc...  vm_pageq.c relates to finding free pages and aquiring
exclusive access to a page queue (exclusivity part not yet implemented).
And the world still builds... :-)
