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
