i386 kernels compile with BIOS_DEBUG again.

This "power saving" disables the apic when both cpu cores hit the hlt
instruction which kills our timer.

512) bytes; ffs is inextricably tied to using b_blkno and disklabel
always uses sectorsize units.
Thus use DEV_BSIZE units for all fields describing ffs filesystems
and convert to/from sectors where required. This enables the creation
and use of ffs filesystems on non-512 byte sectorsize devices.
This diff allows i386 and sgi (the two test platforms) to find
disklabels that are not on a sectorsize boundary. Same change to
further archs coming.
This is a no-op on 512-byte sectorsize devices.
This work triggered by jsing@'s need to create ffs filesystems on
sgi cdroms so we can create cdrom install media for sgi.

Right now when mi_switch picks up the same proc, we didn't clear the
flag which would mean that every time we service an AST we would attempt
a context switch. For some architectures, amd64 being probably the
most extreme, that meant attempting to context switch for every
trap and interrupt.
Now we clear_resched explicitly after every context switch, even if it
didn't do anything. Which also allows us to remove some more code
in cpu_switchto (not done yet).

parameter and returns an aligned random load address for position
independent executables to use. This also adds three new vmparam.h
defines to specify the maximum address, minimum address and minimum
allowed alignment for uvm_map_pie() to use. The PIE address range
for i386 was carefully selected to work well within the i386 W^X
framework.
With much help and feedback from weingart@.

For now, only one such flag is defined, PCKBC_CANT_TRANSLATE. It hints
pckbc that the device does not behave correctly to the ``set translation''
commands.
Set this flag if we are running on a Tadpole Ultrabook machine, which needs it.
This makes the built-in keyboard work correctly on this laptop (with the
help of the software translation pckbd diff).

was an extremely small chance that random stack garbage coudl be used which
could corrupt a dmamap.
this is the same as the change made to amd64 in

this hardware so it is not necessary to return a higher priority

Intel don't publish the EST voltage tables, and they don't
even publish the MSRs for a shipping processor so we
can figure out how to do this in the backwards highest/lowest
way cleanly.
The mapping might look like the Core * one, but who really knows
for sure outside of a few guys at Intel. Other machines with
Atom processors and a different bus clock will have to be added
one by one until this stupidity changes.

* For amd64, remove pcibios traces.
* make RBUS_IO_START, RBUS_IO_SIZE, RBUS_MIN_START and RBUS_MEM_SIZE
(on i386) configurable via kernel options.
* Remove unneeded headers.
* Some cleanups.

kettenis@ and miod@ agrees that although not perfect, this is the right
direction.

k8pnow_transition handles the actual transition, this change is
necessitated by some of the ACPI work which can involve dynamic changes
in the available states in response to endogenous events such as removing
the AC power. This new code is designed to cope with the current operating
point not being among the newly available states in which case we
recalculate what the current desired performance level coresponds to among
the new states.
Also fix a screw up with the acpi_states function (fix originally by
Markus Hennecke in a diff to tech@ thanks) which resolves PR 5854. Diff
tested by numerous people thanks!

Not sure what's more surprising: how long it took for NetBSD to
catch up to the rest of the BSDs (including UCB), or the amount of
code that NetBSD has claimed for itself without attributing to the
actual authors.

(EDD) is found and OK. it will also fix chainloading into OpenBSD from
grub in a few scenarios where grub doesn't report the CHS correctly
but the LBA. and we don't need CHS if there is LBA.

similar to auich(4) and auixp(4), but the hardware dependent parts
are quite different.

simple, it is just another mbr at the partition offset (well, the
standard "EBR" is a linked list with a few limitations, but this diff
works with both variants).
