Changes v7->v8:
- Remove Kconfig depends statement entirely, instead of ACPI||OF.
- Check platform_get_irq() return value against < 0 rather than !0.
This is a cleanup of Sudan's OF vmgenid patches, simplified a bit, but
still with the same intent and mostly unchanged. I'll take this via my
random tree, but Krzysztof, I would appreciate having your ack/review on
it.
Sudan - if I've mangled something here, please let me know. I verified
this still works with ACPI in QEMU, but I don't know about your private
firecracker OF branch, so please pipe up if something is amiss. It's
basically the same thing, though, so I suspect it'll be fine.
