[RFC PATCH] Exporting ACPI Pxx/Cxx states to other kernel subsystems (v1).
Hello, The following patches are a solution to a problem we have encountered when using the Xen hypervisor: - Need Pxx/Cxx states to save on power consumption when using Xen (we do want those datacenters to consume less power!), - Also need to figure out the Turbo mode so that the scheduler can properly boost a core for CPU bound guests. In essence the Xen hypervisor requires that
