I think this patch looks fine.

Acked-by: Hirokazu Takata <takata@xxxxxxxxxxxxxx>

BTW, I need an additional patch to fix a build error, 
caused by the above patch.

[PATCH] m32r: build fix of arch/m32r/kernel/smpboot.c

This patch is for Mathieu Desnoyers's include/asm-m32r/local.h.
Applying the new include/asm-m32r/local.h, inclusion of linux/sched.h
is needed to fix a build error of arch/m32r/kernel/smpboot.c.
