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"
