From 6020c8f315709a508b027ef6749e85b125190947 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 7 Dec 2006 02:14:08 +0100 Subject: [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.
