as you see already, there's some ACPI function duplicated into a Xen specific
version to handle some tricky assumptions, such as
xen_acpi_processor_get_power_info.
So it's possible that, if same kernel works well natively, those Xen stubs are
out of
sync with original version. This is not a clean approach, and we need consider
a better
one for pushing them upstream. :/
