Subject: [PATCH 5/9] mmzone: add pgdat_{end_pfn,is_empty}() helpers & consolidate.
Date: Thu, 17 Jan 2013 14:52:57 -0800	[thread overview]
Message-ID: <1358463181-17956-6-git-send-email-cody@linux.vnet.ibm.com> (raw)
In-Reply-To: <1358463181-17956-1-git-send-email-cody@linux.vnet.ibm.com>

From: Cody P Schafer <jmesmon@gmail.com>

Add pgdat_end_pfn() and pgdat_is_empty() helpers which match the similar
zone_*() functions.

Change node_end_pfn() to be a wrapper of pgdat_end_pfn().
