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 core updates: - Make the watchdog respect the selected CPU mask again. That was broken by the rework of the watchdog thread management and caused inconsistent state and NMI watchdog being unstoppable. - Ensure that the objtool build can find the libelf location. - Remove dead kcore stub code" * 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: watchdog: Respect watchdog cpumask on CPU hotplug objtool: Query pkg-config for libelf location proc/kcore: Remove unused kclist_add_remap()
