instead, just dec/inc in the ctor/dtor. For now, increment/decrement
in two's, since we're now performing the operation once per pair,
not once per pipe. Not really any measurable performance change
in my micro-benchmarks, but doing less work is good, especially when
it comes to atomic operations.

the system. Also, decrease the poll interval to 10 seconds from 30
seconds. This is needed because some systems will report an invalid high
temperature for one poll cycle. It is suspected this is due to the
embedded controller timing out. A typical value is 138C for one cycle on a
system that is otherwise 65C. This prevents the system from prematurely
shutting down after one invalid reading. It will still shut down after 30
seconds of high temperature, which is the same as previous default
behavior.

Also, for now, don't do anything special in the ndis_suspend() method.
I originally wanted to shut down the NIC but leave the IFF_UP flag alone
since technically the interface is meant to remain up, but an interrupt
may be delivered to the ISR on suspend, and if this happens while the
NIC is halted, we will crash, since none of the miniport driver methods
will function.
This needs to be dealt with properly later, but for now this prevents
a panic, and the resume method properly re-inits the NIC.
the thread that calls pmap_pte_quick() and by virtue of the page queues
lock being held, we can manage PADDR1/PMAP1 as a CPU private mapping.
The most common effect of this change is to reduce the overhead of the page
