Ack.

I'd prefer the MSI swizzling bit to stay last in the series. I want to stare hard at the hyperv-iommu part a bit more, and ideally even have it tested. I'd prefer the real functionality that I care about, not to depend on that cleanup.
If it actually let me remove all mention of ext_dest_id from the IOAPIC code and use *only* MSI swizzling, I'd be keener to reorder. But as noted, there are a couple of manual RTE constructions in there still anyway.
I can move __irq_compose_msi_msg() earlier in the series though, and then virt_ext_dest_id can be static in apic.c from its inception.
OK?
