hotplug: Fix UP bug in smpboot hotplug code
Because kernel subsystems need their per-CPU kthreads on UP systems as well as on SMP systems, the smpboot hotplug kthread functions must be provided in UP builds as well as in SMP builds. This commit therefore adds smpboot.c to UP builds and excludes irrelevant code via #ifdef. Signed-off-by: Paul E. McKenney <paul.mckenney@linaro.org> Signed-off-by: Paul E.
