[PATCH 7/7] hang and lockup detection menu

From: Dave Hansen
Date: Tue May 07 2013 - 16:47:02 EST



From: Dave Hansen <dave.hansen@xxxxxxxxxxxxxxx>

The hard/softlockup and hung-task entries take up 6 lines
of screen real-estate when enabled. I bet folks don't
mess with these _that_ often, so move them in a group
down a level.
