KVM: s390: Changes for 4.10 (via kvm/next)

Browse source

Two small optimizations to not do register reloading in
 vcpu_put/get, instead do it in the ioctl path. This reduces
 the overhead for schedule-intense workload that does not
 exit to QEMU. (e.g. KVM guest with eventfd/irqfd that
 does a lot of context switching with vhost or iothreads).
