Subject: [PATCH 1/3] mips: zero out pg_data_t when it's allocated

From: Minchan Kim <[email-masked]>
Date: Tue, 24 Jul 2012 10:10:33 +0900

This patch is ready for next patch which try to remove zero-out
of pg_data_t in core MM part. At a glance, all archs except this part
already have done it so this patch makes consistent with other archs.
