OK, this does apply, but it doesn't fail in the way I had expected.  
Actually, it doesn't barf at all because the generated domain that my 
patch removes has 0 IRQ's so it never gets attached to the irq_desc's.

However, this patch is still valid as we end up with two domains 
associated with the VIC but we get lucky as the real domain is 
registered first.  I can update the patch description to reflect this if 
you still want to apply it.

Incidentally, I've managed to get the versatile kernel booting under 
qemu (using an experimental build with DT support, up to trying to mount 
a rootfs), which seems to work nicely.  I just need to find a suitable 
rootfs and that'll be a nice test system.
