I think this got taken care of by:
commit c59687f8466df36633d937cc298aad465d704990

cpuidle / ACPI : remove power from acpi_processor_cx structure
Remove the unused power field from struct struct acpi_processor_cx.
[rjw: Modified changelog.]
And the the xen_processor_cx is allocated using kcalloc which resets
everything to zero - so I think we are safe there.
Thx!
