[PATCH] paravirt: Allow disable power management under hypervisor
Two legacy power management modes are much easier to just explicitly disable when running in paravirtualized mode - neither APM nor PnP is still relevant. The status of ACPI is still debatable, and noacpi is still a common enough boot parameter that it is not necessary to explicitly disable ACPI.
