[PATCH 2.6.10-mm2] m32r: build fix

[Hirokazu Takata]

Hi,

This patch is required to fix compile errors of 2.6.10-bk8 and 2.6.10-mm2
for m32r.  Please apply.

This was originally given by the following patch:
  [PATCH] move irq_enter and irq_exit to common code
  http://www.ussg.iu.edu/hypermail/linux/kernel/0411.1/1738.html

I think it was maybe accidentally dropped only for the m32r arch
due to a patching conflict with the other patches or something like that...

Thanks,
