The savevm code for the powerpc cpu emulation is currently based around the old register_savevm() rather than register_vmstate() method. It's also rather broken, missing some important state on some CPU models. This patch completely rewrites the savevm for target-ppc, using the new VMStateDescription approach. Exactly what needs to be saved in what configurations has been more carefully examined, too. This introduces a new version (5) of the cpu save format. The old load function is retained to support version 4 images.
