ae85e6b957 Random underdocumented CPU facts: 
AMD K8 and newer will trap when enabling the NX support outside PAE
paging mode. The AMD64 wake code was restoring the MSR EFER to switch to
Long Mode and naturally didn't have paging enabled at that point.
While this works fine with Intel CPUs, it resulted in an immediate
reboot with AMD processors.

Fixed by a joint brain storming session of jmcneill@, cegger@ and
myself, based on some input from the hardware developers.  This fixes
PR 38587.

77b766af04 Back out the removal of md(4) in order to permit this port to complete 
a release build again.  The GENERIC kernel is used to build install media
in distrib/ibmnws/netboot/kernel, and without the md(4) area in place,
mdsetimage becomes unhappy.

Pointed out to rjs (who removed md(4) in revision 1.31), but now
committed due to feedback time-out, and because I've verified that
this fixes the build.

bf1cf71fcd - cpu_attach: ensure that the boot processor is set up before trying to 
initialize APs. We need the lapic set up and the boot processor may
  not be attached first.

- mp_cpu_start: write back and invalidate the data cache before starting the
  init IPI sequence. If a buggy BIOS has left the AP with cache disabled,
  it might not be able to participate in the cache coherency protocol.

Original description:
Don't use the legacy interrupt when deciding how to route IOAPIC pins.
On some modern systems not all devices have the PCI interrupt line
set, typically the cardbus bridge is affected and it would result in
different interrupt vectors used for the same IOAPIC pin.
To allow this, simplify the code by checking for an existing match first
and only allocate a new entry if that doesn't exist. For the IOAPIC case
don't bother with the reserveration on the primary CPU for ISA
interrupts, just use them.

e4ea82cddb Add support to pxeboot to allow the loading of modules. Changes to main.c 
are taken from boot/boot2.c.

This allows an install to be started by running:
load tftp:miniroot.kmod
boot tftp:netbsd-GENERIC

Note that the change to dev_net.c to comment out the network shutdown,
suggests we need to hook the network shutdown in the the common exec code.
If the network is shutdown, it fails to reinitialise and so fails to load
the module.

this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more

75ada79f33 Improve x86 tsc handling: 
- Ditch the cross-CPU calibration stuff. It didn't work properly, and it's
  near impossible to synchronize the CPUs in a running system, because bus
  traffic will interfere with any calibration attempt, messing up the
  timings.

- Only enable the TSC on CPUs where we are sure it does not drift. If we are
  On a known good CPU, give the TSC high timecounter quality, making it the
  default.

- When booting CPUs, detect TSC skew and account for it. Most Intel MP
  systems have synchronized counters, but that need not be true if the
  system has a complicated bus structure. As far as I know, AMD systems
  do not have synchronized TSCs and so we need to handle skew.

- While an AP is waiting to be set running, try and make the TSC drift by
  entering a reduced power state. If we detect drift, ensure that the TSC
  does not get a high timecounter quality. This should not happen and is
  only for safety.

- Make cpu_counter() stuff LKM safe.

It wasn't noticed till now as it wasn't overflowing onto anything
important (or was overwritten by the correct data).  Recent changes
meant irqstr was placed just before footbridge_intrq and so it trashed
the interrupt linked list, and so caused an alignment fault.

Note that cats still doesn't boot even with the change, as it hangs when
starting userland, I suspect an interrupt issue.
