exec: cpu_physical_memory_set/clear_dirty_range
Make cpu_physical_memory_set/clear_dirty_range behave symmetrically. To clear range for a given client type only, add cpu_physical_memory_clear_dirty_range_type. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Paolo Bonzini <pbonzini@redhat.com>
