From 71b3d3e37269029bd9351c7504d36401ecc6046a Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Wed, 21 Oct 2015 10:09:49 +0100 Subject: arm64: KVM: Add a HYP-specific header file In order to expose the various EL2 services that are private to the hypervisor, add a new hyp.h file. So far, it only contains mundane things such as section annotation and VA manipulation.
