I've sent a v2 a couple of weeks ago:

I hope so. If I can't get the whole series in Xen 4.5, I will at least
try to get the interrupt assignment in it.

The new approach allocate dynamically the virtual IRQ number. I chose
this solution because otherwise Xen is allocating memory which is never
used.
You could hack this patch to support 1:1 (see vgic_allocate_virq and
vgic_free_virq).
OOI, why do you need Virtual IRQ == Physical IRQ?

IIRC, there was few comments in the v2 and no v3 has been sent after.
