From 17b1e31f9201fc102ee3ddd409988e47753e22f9 Mon Sep 17 00:00:00 2001 From: Marc Zyngier Date: Mon, 8 Apr 2013 16:47:18 +0100 Subject: [PATCH] ARM: KVM: add architecture specific hook for capabilities Most of the capabilities are common to both arm and arm64, but we still need to handle the exceptions. Introduce kvm_arch_dev_ioctl_check_extension, which both architectures implement (in the 32bit case, it just returns 0).
