From 15e0d9e37c7fe9711b60f47221c394d45553ad8c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 1 Oct 2011 21:09:39 +0200 Subject: [PATCH] ARM: pm: let platforms select cpu_suspend support Support for the cpu_suspend functions is only built-in when CONFIG_PM_SLEEP is enabled, but omap3/4, exynos4 and pxa always call cpu_suspend when CONFIG_PM is enabled.
