It's been recently reported that GICv2m doesn't handle the Multi-MSI variant (it only deals with a single MSI, or the full blown MSI-X). For better or worse, Multi-MSI is still a thing, and it'd be better if we dealt with it.
This tiny series aims at teaching this old trick to GICv2m, together with an extra patch that enables all the v2m regions on Juno. if nobody objects to this, I plan to take at least the initial patch through the irqchip tree, and potentially the DT as well if people want me to.
