4.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Zyngier <marc.zyngier@arm.com>
commit 95696d292e204073433ed2ef3ff4d3d8f42a8248 upstream.
The GIC-500 integrated in the Armada-37xx SoCs is compliant with
the GICv3 architecture, and thus provides a maintenance interrupt
that is required for hypervisors to function correctly.
With the interrupt provided in the DT, KVM now works as it should.
Tested on an Espressobin system.
Fixes: adbc3695d9e4 ("arm64: dts: add the Marvell Armada 3700 family and a development board")
