[PATCH 3/3] proc: add pageblock size info to /proc/meminfo

[Bartlomiej Zolnierkiewicz]

From: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>
Subject: [PATCH] proc: add pageblock size info to /proc/meminfo

Pageblock size info is not currently exported to user-space
while it is useful to know it when using with new /proc/kpagetype
interface.
