From 93180cec0064d072a984f91c429c5e6bcc816976 Mon Sep 17 00:00:00 2001 From: Minchan Kim Date: Tue, 31 Jul 2012 16:46:11 -0700 Subject: [PATCH] mips: zero out pg_data_t when it's allocated This patch is preparation for the next patch which removes the zeroing of the pg_data_t in core MM. All archs except MIPS already do this.
