Merge branch 'core/softlockup' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'core/softlockup' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: softlockup: make DETECT_HUNG_TASK default depend on DETECT_SOFTLOCKUP softlockup: move 'one' to the softlockup section in sysctl.c softlockup: ensure the task has been switched out once softlockup: remove timestamp checking from hung_task softlockup: convert read_lock in hung_task to rcu_read_lock softlockup: check all tasks in hung_task softlockup: remove unused definition for spawn_softlockup_task softlockup: fix potential race in hung_task when resetting timeout softlockup: fix to allow compiling with !DETECT_HUNG_TASK softlockup: decouple hung tasks check from softlockup detection
