[RFC] pvops domain0 Cx/Px info parser patch
...anged, acpi_processor_cst_has_changed, to finish the acpi info parsing.
So the conclusion is: adding hooks in acpi_processor_driver and those related library functions will satisfy our requirement.
To make the added hook cleaner, we introduce an interface called external control operation (struct processor_extcntl_ops). All the hooks are encapsulated in this interface processor_extcntl_ops . Here the "external" means the acpi processor is controlled by external entity, e.g. VMM. Every kind of external entity can has its implementation of this interface. In this patch, the interface for Xen is implemen...

[PATCH] linux: fix processor handling in presence of external control
- avoid leaking stuff in acpi_processor_remove()
- remove a pointless change to native code in acpi_processor_hotplug()
(struct acpi_processor''s id field is unsigned)
- don''t set up processor_extcntl_ops when nothing controlled by Xen
(thus processor_cntl_external() will always return false, allowing
ACPI code to retain native behavior)
As usual, written and tested on 2.6.27-rc6 and made apply to the 2.6.18
tree without further testing.
