matt 3e3119f9fe Default PMAP_KMPAGE to 0 unless it's been previously defined by 
<machine/pmap.h>
 2008-07-16 14:33:09 +00:00
matt ad65eb54bc Add PMAP_KMPAGE flag for pmap_kenter_pa. This allows pmaps to know that 
the page being entered is being for the kernel memory allocator.  Such pages
should have no references and don't need bookkeeping.

ad 83828e8d22 listq -> listq.queue 2008-06-04 13:23:30 +00:00
ad cbbf514e2c - vm_page: put listq, pageq into a union alongside a LIST_ENTRY, so we can 
use both types of list.

- Make page coloring and idle zero state per-CPU.

- Maintain per-CPU page freelists. When freeing, put pages onto the local
  CPU's lists and the global lists. When allocating, prefer to take pages
  from the local CPU. If none are available take from the global list as
  done now. Proposed on tech-kern@.

ad e071d39c84 - Convert hashinit() to use kmem_alloc(). The hash tables can be large 
and it's better to not have them in kmem_map.
- Convert a couple of minor items along the way to kmem_alloc().
- Fix some memory leaks.

yamt fb0cfeb7dd fix a locking botch. PR/38415 from Wolfgang Solfrank. 2008-04-26 13:44:00 +00:00
ad 6d70f903e6 Network protocol interrupts can now block on locks, so merge the globals 
proclist_mutex and proclist_lock into a single adaptive mutex (proc_lock).
Implications:

- Inspecting process state requires thread context, so signals can no longer
  be sent from a hardware interrupt handler. Signal activity must be
  deferred to a soft interrupt or kthread.

- As the proc state locking is simplified, it's now safe to take exit()
  and wait() out from under kernel_lock.

- The system spends less time at IPL_SCHED, and there is less lock activity.
