[Yuval Shaia <yuval.shaia-QHcLZuEGTsvQT0dZR+AlfA@public.gmane.org>]

v0 -> v1:
	* s/"min_t("/"min_t(int"
v1 -> v2:
	* Use min3 instead of min_t twice
v2 -> v3:
	* Change commit log header message to reflect the changes made in
	  v2
v3 -> v4:
	* Cast return value from num_online_cpus to int to avoid
	  compilation errors from "sparse"
