[Xen-devel] [PATCH v3 3/8] ARM: VGIC: split up gic_dump_info() to cover virtual part separately

[Andre Przywara <andre.przywara@xxxxxxxxxx>]

Currently gic_dump_info() not only dumps the hardware state of the GIC,
but also the VGIC internal virtual IRQ lists.
Split the latter off and move it into gic-vgic.c to observe the abstraction.
