[PATCH 3/3] arch/sh: use __page_aligned_bss

From: Jeremy Fitzhardinge
Date: Wed May 28 2008 - 12:05:57 EST


The patch "make page-aligned data and bss less fragile" introduces
__page_aligned_data and __page_aligned_bss to make sure that page
aligned things remain so, even if there are non-page-sized
page-aligned things.

This paragraph converts the two C instances of page-aligned bss
variables to use them. It's a purely decorative patch.
