From a0bf9776cd0be4490d4675d4108e13379849fc7f Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Tue, 16 Feb 2016 13:52:39 +0100 Subject: arm64: kvm: deal with kernel symbols outside of linear mapping KVM on arm64 uses a fixed offset between the linear mapping at EL1 and the HYP mapping at EL2. Before we can move the kernel virtual mapping out of the linear mapping, we have to make sure that references to kernel symbols that are accessed via the HYP mapping are translated to their linear equivalent.
