From 485cf5dac2966b93ef2b6211cf2fd42d66c823e6 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Wed, 24 Apr 2013 17:19:13 -0700 Subject: [PATCH] idle: Fix hlt/nohlt command-line handling in new generic idle commit d1669912 (idle: Implement generic idle function) added a new generic idle along with support for hlt/nohlt command line options to override default idle loop behavior. However, the command-line processing is never compiled. The command-line handling is wrapped by CONFIG_GENERIC_IDLE_POLL_SETUP and arches that use this feature select it in their Kconfigs. However, no Kconfig definition was created for this option, so it is never enabled, and therefore command-line override of the idle-loop behavior is broken after migrating to the generic idle loop. To fix, add a Kconfig definition for GENERIC_IDLE_POLL_SETUP. Tested on ARM (OMAP4/Panda) which enables the command-line overrides by default. Signed-off-by: Kevin Hilman Reviewed-by: Srivatsa S.
