Merge tag 'trace-fixes-v3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace

Pull tracing fixes from Steven Rostedt:
 "Here's two fixes:

  1) Discovered by Fengguang Wu's tests.  I changed the parameters to
     the function graph x86 prepare_ftrace_return call but forgot to
     update the call from entry_32 (i386 version).  This patch corrects
     that.

  2) I was tracing some code and found that the sched_switch tracepoint
     was showing tasks in the INTERRUPTIBLE state as RUNNING.  This was
     due to the updates to convert preempt_count into a per_cpu
     variable.  The tracepoint logic was made to use the tasks
     saved_preempt_count which could hold a stale "PREEMPT_ACTIVE",
     instead of using the current preempt_count() call"
