Frederic Weisbecker 6775de4984 context_tracking: Only define schedule_user() on !HAVE_CONTEXT_TRACKING_OFFSTACK archs ... schedule_user() was traditionally used by the entry code's tail to preempt userspace after the call to user_enter(). Indeed the call to user_enter() used to be performed upon syscall exit slow path which was right before the last opportunity to schedule() while resuming to userspace. The context tracking state had to be saved on the task stack and set back to CONTEXT_KERNEL temporarily in order to safely switch to another task. Only a few archs use it now (namely sparc64 and powerpc64) and those implementing HAVE_CONTEXT_TRACKING_OFFSTACK definetly can't rely on it.
