From 296699de6bdc717189a331ab6bbe90e05c94db06 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 29 Jul 2007 23:27:18 +0200 Subject: Introduce CONFIG_SUSPEND for suspend-to-Ram and standby Introduce CONFIG_SUSPEND representing the ability to enter system sleep states, such as the ACPI S3 state, and allow the user to choose SUSPEND and HIBERNATION independently of each other. Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has been chosen and the kernel is intended for SMP systems. Also, introduce CONFIG_PM_SLEEP which is automatically selected if CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the code needed for both suspend and hibernation. The top-level power management headers and the ACPI code related to suspend and hibernation are modified to use the new definitions (the changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce the number of ifdefs). There are many other files in which CONFIG_PM can be replaced with CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in the future. Signed-off-by: Rafael J.
