kvm: reset state from the CPU's reset method
Now that we have a CPU object with a reset method, it is better to keep the KVM reset close to the CPU reset. Using qemu_register_reset as we do now keeps them far apart. With this patch, PPC no longer calls the kvm_arch_ function, so it can get removed there. Other arches call it from their CPU reset handler, and the function gets an ARMCPU/X86CPU/S390CPU. Note that ARM- and s390-specific functions are called kvm_arm_* and kvm_s390_*, while x86-specific functions are called kvm_arch_*. That follows the convention used by the different architectures. Changing that is the topic of a separate patch. Reviewed-by: Gleb Natapov <gnatapov@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
