[PATCH 15/53] sched/headers: Move softlockup detector watchdog methods to <linux/nmi.h>

[Ingo Molnar <mingo@kernel.org>]

These methods don't belong into <linux/sched.h>, they are neither directly
related to task_struct or are scheduler functionality.

Put them next to the other watchdog methods in <linux/nmi.h>.

( Arguably that header's name is a misnomer, and this patch makes it
  more so - but it should be renamed in another patch. )
