[Qemu-devel] [PATCH qom-cpu v3 0/6] QOM CPUState migration, next generation

["Andreas Färber" <afaerber@suse.de>]

Hello,

As previously reported, alpha and openrisc had prepared VMStateDescriptions
but failed to register them due to lack of CPU_SAVE_VERSION.

Now that CPUState is a DeviceState, it was suggested to register the VMState
of new CPUs the same way devices do. They thereby deviate from legacy CPUs,
which register a separate VMStateDescription for the common state.

The series still concludes with a patch to prevent further silent migration
registration bugs.

Regards,
Andreas

v2 -> v3:
* Prepended patch introducing VMSTATE_CPU() macro for vmstate_cpu_common.
* Prepended patch adding device_class_set_vmsd().
* Added typo fix patch for cpu_class_set_vmsd().
* Register AlphaCPU and OpenRISCCPU vmsd via DeviceClass instead of CPUClass.
