From a4097b351118e821841941a79ec77d3ce3f1c5d9 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Tue, 6 Feb 2018 17:56:13 +0000 Subject: arm/arm64: KVM: Turn kvm_psci_version into a static inline We're about to need kvm_psci_version in HYP too. So let's turn it into a static inline, and pass the kvm structure as a second parameter (so that HYP can do a kern_hyp_va on it).
