From 25ac77613aa8fca131599705e3d7da2a0eaa06a0 Mon Sep 17 00:00:00 2001 From: Daniel Lezcano Date: Thu, 5 Jul 2012 15:23:25 +0200 Subject: ACPI: intel_idle : break dependency between modules When the system is booted with some cpus offline, the idle driver is not initialized. When a cpu is set online, the acpi code call the intel idle init function. Unfortunately this code introduce a dependency between intel_idle and acpi. This patch is intended to remove this dependency by using the notifier of intel_idle. This patch has the benefit of encapsulating the intel_idle driver and remove some exported functions.
