[PATCH 3/7] mm/memblock: memblock_is_memory/reserved can be boolean

From: Yaowei Bai
Date: Mon Nov 16 2015 - 01:52:58 EST


This patch makes memblock_is_memory/reserved return bool to improve
readability due to this particular function only using either
one or zero as its return value.

No functional change.
