[Xen-devel] [PATCH 0/2] xen/arm: GICv3: Only initialize ITS when LPIs are available

Hi all,

This small patch series fix an issue I discovered when using the Foundation
model and the DT provided by Linux upstream.

Indeed the Device-Tree is exposing an ITS but LPIs are not available.
Resulting to an early crash on Xen.

Whilst this looks a DT issue, Linux is able to cope with it. So I think Xen
should also cope with such DT.
