Update of /cvsroot/src/sys/kern
In directory netbsd1:/var/slash-tmp/cvs-serv1695

Modified Files:
	subr_extent.c 
Log Message:
Several changes:
- Rename EX_NOBLOB to EX_NOCOALESCE; it's much more descriptive of
  what's going on.
- In extent_free_region_descriptor(), if we're a fixed extent,
  freeing a dynamically allocated region descriptor, and someone
  is waiting on the freelist, let the waiter have it, rather than
  free'ing it back to the system.
- Use ALIGN(), rather than our homegrown EXTENT_ALIGN(), when dealing
  with map overhead.  Privatize the EXTENT_ALIGN() macro; there's no need
  to export it.
- Implement EX_BOUNDZERO flag.  This changes the boundary line policy in
  extent_alloc() and extent_alloc_subregion(); boundary lines are 
  computed relative to 0, rather then the start of the extent.
- Fix a nasty race between multiple participants doing region and
  descriptor allocation.
- Add a new flag to specify that it's ok to wait for space in the
  extent: EX_WAITSPACE.
- Blow away an unnecessary splhigh()/splx().
- Put a bunch of sanity code inside #ifdef DIAGNOSTIC/#endif.
