The patch titled
Subject: include/linux/smp.h: define __smp_call_function_single for !CONFIG_SMP
has been removed from the -mm tree. Its filename was
watchdog-update-watchdog_tresh-properly-fix.patch
This patch was dropped because it was folded into watchdog-update-watchdog_tresh-properly.patch
------------------------------------------------------
From: Michal Hocko <mhocko@xxxxxxx>
Subject: include/linux/smp.h: define __smp_call_function_single for !CONFIG_SMP
This function was not needed until (watchdog: update watchdog_tresh
properly) which cannot use on_each_cpu unfortunately as
watchdog_nmi_enable relies on perf_event_alloc which is might sleep.
Export it as an alias to on_each_cpu for !CONFIG_SMP.
