- move src/arch/i386/smp/ioapic.c to src/arch/i386/lib/ioapic.c (has
nothing to do with SMP)
- move src/arch/i386/smp/mpspec.c to src/arch/i386/boot/mpspec.c (where
acpi, pirq and coreboot table generation lives)
- modify src/arch/i386/boot/Makefile.inc,
src/arch/i386/lib/Makefile.inc
and src/arch/i386/smp/Makefile.inc accordingly
- src/arch/i386/smp is now empty. drop it.
- drop src/arch/i386/init/car.S (unused)
