From 6352e4d2dd9a349024a41356148eced553e1dce4 Mon Sep 17 00:00:00 2001 From: David Hildenbrand Date: Thu, 10 Apr 2014 17:35:00 +0200 Subject: KVM: s390: implement KVM_(S|G)ET_MP_STATE for user space state control This patch - adds s390 specific MP states to linux headers and documents them - implements the KVM_{SET,GET}_MP_STATE ioctls - enables KVM_CAP_MP_STATE - allows user space to control the VCPU state on s390. If user space sets the VCPU state using the ioctl KVM_SET_MP_STATE, we can disable manual changing of the VCPU state and trust user space to do the right thing.
