- Move the functionality of choosing a process from cpu_switch into
a much simpler function: cpu_switchto. Instead of having the locore
code walk the run queues, let the MI code choose the process we
want to run and only implement the context switching itself in MD
code.
- Let MD context switching run without worrying about spls or locks.
- Instead of having the idle loop implemented with special contexts
in MD code, implement one idle proc for each cpu. make the idle
loop MI with MD hooks.
- Change the proc lists from the old style vax queues to TAILQs.
- Change the sleep queue from vax queues to TAILQs. This makes
wakeup() go from O(n^2) to O(n)
there will be some MD fallout, but it will be fixed shortly.
There's also a few cleanups to be done after this.

tested by krw@. This diff by itself is insufficient to ensure that
we are only running on an amd64: todd@'s machine is a mobile Athlon XP
that has a cpuid family of 0xf but is not an amd64 processor so more
must be done but this should prevent the vast majority of cases.

enough systems today do not have apm. Also, the existance
of apm is given on the probe line, absence means it ain't
there.

the holes a MMU may have from a given vm_map. This will be automagically
invoked for newly created vmspaces.
On platforms with MMU holes (e.g. sun4, sun4c and vax), this prevents
mmap(2) hints which would end up being in the hole to be accepted as valid,
causing unexpected signals when the process tries to access the hole
(since pmap can not fill the hole anyway).
Unfortunately, the logic mmap() uses to pick a valid address for anonymous
mappings needs work, as it will only try to find an address higher than the
hint, which causes all mmap() with a hint in the hole to fail on vax. This
will be improved later.

check that the maxfid and the highest reported acpi p_state frequency agree only
after actually getting the acpi p_state. Secondly prefer the legacy powernow
table over ACPI because machines of this vintage of are likely to have broken
ACPI implementations.

no support for 802.11n functions yet (need work in net80211(9) first).

bmc's watching on the shared bus. if you disable ipmi, you might see it
pop up (reminder why ipmi / i2c mixes are disabled: some ipmi's seem to
violate the i2c bus locking protocol). tested by Alexander Lobodzinski

from a local disk, since the MAC address causes the kernel to look for
root on NFS. Do this by remembering (not adding to boot arguments) the
MAC address when opening the PXE device, and clearing this if we happen
to load a file off a non-network disk.

p_state data based on similar work done to powernow-k8.c. This work was
done by Devin Smith <devin at devinsmith dot net> and this commit is a
slightly modified verson of his last diff to tech@, thanks again for your
work.
