3.19.8-ckt18 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Ingo Molnar <mingo@xxxxxxxxxx>
commit 590ee7dbd569a012df705a5204fc5f1066f52b8c upstream.
Now that we are using smpboot_thread_init() in init/main.c as well,
provide it for !CONFIG_SMP as well.
This addresses a !CONFIG_SMP build failure.
