From 825257569350e913bee3bc918508c0aa6e3398cd Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 19 Nov 2007 23:49:18 +0100 Subject: PM: Convert PM notifiers to out-of-line code This patch (as1008b) converts the PM notifier routines from inline calls to out-of-line code. It also prevents pm_chain_head from being created when CONFIG_PM_SLEEP isn't enabled, and EXPORTs the notifier registration and unregistration routines.
