From 70806b21e4d64f01193a2b64a053b75ff53a2b10 Mon Sep 17 00:00:00 2001
From: Ingo Molnar <mingo@kernel.org>

Subject: sched/headers: Move the 'root_task_group' declaration to
 <linux/sched/autogroup.h>

Also remove the duplicate declaration from <linux/init_task.h>.

( That declaration was originally duplicated for dependency hell reasons,
  but there's no problem including the much smaller <linux/sched/autogroup.h>
  header now, to pick up the right prototype. )
