Seperate "cpubus" and "ioapicbus" -- while they share a common "address
space" (the apic id), the kernel doesn't use this fact. There are different
data passed to cpus and apics, which caused some ugly polymorphism. This
also saves the special "submatch" functions needed to distingush cpus
and ioapics for autoconf. (And it makes that "apid" locators wired
in the kernel configuration are honored now; this allows one to dumb down
an mp box to singleprocessor by userconfig.)
Print "apid" locators in the buses "print" function "as everyone does",
so the per-port cpu drivers don't need to do it.
Being here, constify "struct cpu_functions" and g/c the unused MP_PICMODE
flag.

that allow a (normally broken/limited) device to restrict the bus address
range it can talk to. this is used by bce(4) to limit DMA addresses to
1GB range, the maximum the chip can address.
all this is from Yorick Hardy <yhardy@uj.ac.za> with input from several
people on tech-kern.
XXX: bus_dma(9) needs an update still.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".
Thanks to martin@ for the input on testing.
requests and centralizing them all. The result is that some of these
are not used on some architectures, but the documentation was updated
to reflect that.
- finish implementing splraiseipl (and makeiplcookie).

- complete workqueue(9) and fix its ipl problem, which is reported
to cause audio skipping.
- fix netbt (at least compilation problems) for some ports.
- fix PR/33218.
I didn't know what header to put the prototype in, so it's both in
i386/mem.c and amd64/mem.c; probably can be moved later.
Tested on amd64, assumed working on i386. :)

displayed, to make the code much simpler and easier to follow. Also, use
bitmask_printf() to make output consistent with other stuff. Use
CPUID2FAMILY() where appropriate.
SMBios detection and mapping to bios32.c, also from OpenBSD (for now this
is only compiled in if ipmi(4) is configured). The sensors and watchdog are
accessible though envsys(4).
Works on i386; some work is needed on amd64 to access the BIOS. It would
eventually work on Xen if the SMBios is accessible (to be tested).
- make it possible for machine-specific code to provide custom R/W routines
in its i82093*.h headers
- always initialize sc->sc_pins[pin], even in the !ioapic_cold case.
No objections on port-i386 and port-amd64.
