Subject: [PATCH] typeof __page_to_pfn with SPARSEMEM=y
Date: Fri, 26 Jan 2007 12:01:13 -0800 [thread overview]
Message-ID: <20070126120113.c17c1174.randy.dunlap@oracle.com> (raw)
With CONFIG_SPARSEMEM=y:
mm/rmap.c:579: warning: format '%lx' expects type 'long unsigned int', but argument 2 has type 'int'
Make __page_to_pfn() return unsigned long.
