Since locking sigio_lock is usually followed by calling pgsigio(),
move the declaration of sigio_lock and the definitions of SIGIO_*() to
sys/signalvar.h.
While I am here, sort include files alphabetically, where possible.
mutex class. Currently this is only used for kmapentzone because kmapents
are are potentially allocated when freeing memory. This is not dangerous
though because no other allocations will be done while holding the
kmapentzone lock.
is limiting it to, not what the device says it can handle.
- cl_status is an integer. cl_lstatus is a pointer.
- Add some debugging code to dump some things the driver knows about
the adapter.
- Tell CAM that the adapter can handle more commands when a command
completes. This fixes the problem were the SIM would freeze once
the driver hit the maximum number of transactions for the device.
- Change the vendor string to COMPAQ.
- Turn of Synchronize Cache for now. It locks the controller up.

malloc profiling) also modified the set of pre-defined buckets for the
memory allocator. For reasons unknown to me, this resulted in extensive
memory corruption in the kernel, in particular on SMP boxes, so I'm
committing this work-around until Jeff gets a chance to debug it
properly. David Wolfskill pointed me at this commit as the one that
might be a problem; I've been running this code on two dual-processor
burn-in boxes for about 12 hours now, and the rate of panics due to
memory corruption has dropped to zero (from one every five minutes).

Rename mii_phy_auto_stop() mii_phy_down().
Introduce mii_down(), use it from nge. Do not indirect it to 19 identical
case's in 19 switchstatements like NetBSD did.
Highlights include:
- New low-level trap code from NetBSD. The high level code still needs a lot
of work.
- Fixes for some pmap handling in thread switching.
- The kernel will now get to attempting to jump into init in user mode. There
are some pmap/trap issues which prevent it from actually getting there though.

i386/ia64/alpha - catch up to sparc64/ppc:
- replace pmap_kernel() with refs to kernel_pmap
- change kernel_pmap pointer to (&kernel_pmap_store)
(this is a speedup since ld can set these at compile/link time)
all platforms (as suggested by jake):
- gc unused pmap_reference
- gc unused pmap_destroy
- gc unused struct pmap.pm_count
(we never used pm_count - we track address space sharing at the vmspace)
