From 853c3b21ff35816a2ae351fd7c2adb101c1f4503 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Thu, 30 Jun 2016 18:40:38 +0100 Subject: [PATCH] arm64: Add ARM64_HYP_OFFSET_LOW capability As we need to indicate to the rest of the kernel which region of the HYP VA space is safe to use, add a capability that will indicate that KVM should use the [VA_BITS-2:0] range.
