From edab4fe1f6419fc3a1de3b134929ae2123bea3ad Mon Sep 17 00:00:00 2001 From: James Hogan Date: Tue, 14 Mar 2017 10:15:23 +0000 Subject: KVM: MIPS: Add hardware_{enable,disable} callback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add an implementation callback for the kvm_arch_hardware_enable() and kvm_arch_hardware_disable() architecture functions, with simple stubs for trap & emulate. This is in preparation for VZ which will make use of them.
