Merge branch 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull core fixes from Thomas Gleixner:
 "A small set of updates for core code:

   - Prevent tracing in functions which are called from trace patching
     via stop_machine() to prevent executing half patched function trace
     entries.

   - Remove old GCC workarounds

   - Remove pointless includes of notifier.h"

* 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  objtool: Remove workaround for unreachable warnings from old GCC
  notifier: Remove notifier header file wherever not used
  watchdog: Mark watchdog touch functions as notrace
