b6e48e0372 - Acquire the vm_object's lock when performing vm_object_page_clean(). 
- Add a parameter to vm_pageout_flush() that tells vm_pageout_flush()
   whether its caller has locked the vm_object.  (This is a temporary
   measure to bootstrap vm_object locking.)

de5ef10142 Update locking on the kernel_object to use the new macros. 2003-04-14 00:36:53 +00:00

227f9a1c58 - Add vm_paddr_t, a physical address type. This is required for systems 
where physical addresses larger than virtual addresses, such as i386s
  with PAE.
- Use this to represent physical addresses in the MI vm system and in the
  i386 pmap code.  This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

55df3298c6 o Require that the page queues lock is held on entry to vm_pageout_clean()

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... :-)
