[Qemu-devel] [RFC PATCH v0 1/5] cpu: Factor out cpu vmstate_[un]register into separate routines

[Bharata B Rao]

Consolidates cpu vmstate_[un]register calls into separate routines.
No functionality change except that vmstate_unregister calls are
now done under !CONFIG_USER_ONLY to match with vmstate_register calls.
