a56cbb2afb * When initializing MSI support, don't assume a single 24 entry IO-APIC. Instead
mark the ISA interrupts as unusable and then use ioapic_is_interrupt_available
  to determine if that vector is possibly taken by an IO-APIC. If IO-APICs are
  not used, this will simply always return false, leaving all vectors free for
  MSI use.
* The msi_init() now has to be done after a potential IO-APIC init, so it is now
  done after ioapic_init() instead of inside apic_init().
* Add apic_disable_local_ints() to clear the local ints on the local APIC once
  we are in APIC mode (i.e. the IO-APIC is set up and we don't need the external
  routing anymore).

3d310bd5f4 * Fix build, the APIC definitions are used in the bootloader too.
* Automatic whitespace cleanup.

655f3b4161 Seperate the generic (local) APIC stuff into it's own file and use it from the
other places where previously the same functionality was duplicated. Also
seperated the header which was originally arch_smp.h into apic.h and arch_smp.h
again as some of it is MP and not actually APIC.
