[Xen-devel] [PATCH 51/57] ARM: new VGIC: Add preliminary stub implementation

[Andre Przywara <andre.przywara@xxxxxxxxxx>]

The ARM arch code requires an interrupt controller emulation to implement
vgic_clear_pending_irqs(), although it is suspected that it is actually
not necessary. Go with a stub for now to make the linker happy.
