4e71e795a1 This commit represents work mainly submitted by Tor and slightly modified 
by myself.  It solves a serious vm_map corruption problem that can occur
with the buffer cache when block sizes > 64K are used.  This code has been
heavily tested in -stable but only tested somewhat on -current.  An MFC
will occur in a few days.  My additions include the vm_map_simplify_entry()
and minor buffer cache boundry case fix.

Make the buffer cache use a system map for buffer cache KVM rather then a
normal map.

Ensure that VM objects are not allocated for system maps.  There were cases
where a buffer map could wind up with a backing VM object -- normally
harmless, but this could also result in the buffer cache blocking in places
where it assumes no blocking will occur, possibly resulting in corrupted
maps.

Fix a minor boundry case in the buffer cache size limit is reached that
could result in non-optimal code.

Add vm_map_simplify_entry() calls to prevent 'creeping proliferation'
of vm_map_entry's in the buffer cache's vm_map.  Previously only a simple
linear optimization was made.  (The buffer vm_map typically has only a
handful of vm_map_entry's.  This stabilizes it at that level permanently).

05f6ee66ea Implement preemptive scheduling of hardware interrupt threads. 
- If possible, context switch to the thread directly in sched_ithd(),
  rather than triggering a delayed ast reschedule.

- Disable interrupts while restoring fpu state in the trap handler,
  in order to ensure that we are not preempted in the middle, which
  could cause migration to another cpu.

98eb90094e As the default MAXDSIZ and DFLDSIZ is 512MB, bump the example values 
to 1GB. A box of mine is running with MAXDSIZ and DFLDSIZ increased
up to 1.5GB.

Wishlist: It would be nice to warn if MAXTSIZ + MAXDSIZ + MAXSSIZ
exceeds VM_MAXUSER_ADDRESS - VM_MINUSER_ADDRESS.

a89bda90b1 Added used include of <sys/mutex.h>. The SMP case was broken by 
incompletely converting simplelocks to mutexes (COM_LOCK() is supposed
to hide the SMP locking internals, but it now depends on mutex interfaces
being visible).

84e11fbc2e Move the setting of curproc to idleproc up earlier in ap_init(). The 
problem is that a mutex lock, prior to this change, is acquired before
the curproc is set to idleproc, so we mess ourselves up by calling
the mutex lock routine with curproc == NULL.

Moving it up after the aps_ready spin-wait has us hopefully setting it
after idleproc is setup.

Solved by: jake (the allmighty) :-)
