[Qemu-devel] [PATCH] Fix -M isapc irq routing |

Only send irqs to ioapic in case we have one.
Fixes qemu segfault.
Linux kernel still needs explicit noapic noacpi on the kernel cmd line
to boot. Do we need a different bios for isapc? Or a fw_cfg knob to
turn off all the modern stuff (apic, acpi, smp, ...)?
