Subject: [Variant 2/Spectre-v2] arm/arm64: KVM: Consolidate the PSCI include files

From: Marc Zyngier <marc.zyngier@arm.com>


Commit 1a2fb94e6a77 upstream.

As we're about to update the PSCI support, and because I'm lazy,
let's move the PSCI include file to include/kvm so that both
ARM architectures can find it.
