Merge branch 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull stacktrace fix from Thomas Gleixner:
"A small fix for a stacktrace regression.
Saving a stacktrace for a foreign task skipped an extra entry which
makes e.g. the output of /proc/$PID/stack incomplete"
* 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
stacktrace: Don't skip first entry on noncurrent tasks
