Inspired by the split irqchip patches, this series limits the IOAPIC<->LAPIC to the EOI exit bitmap that is inferred from the redirection table.
TMR is entirely handled within the local APIC, and no global copy of the IOAPIC-handled vectors is necessary anymore. This makes it simpler to introduce a userspace IOAPIC. Tested with ioapic.flat for now, planning to do more complete tests tomorrow. The most interesting test to do here is an assigned device that uses INTX, so I am CCing Alex Williamson for a heads up.
