From 204ecae4e10c235e6987cb7b2809a665511ab174 Mon Sep 17 00:00:00 2001 From: Russell King Date: Tue, 16 Jan 2007 14:01:47 +0000 Subject: [PATCH] [ARM] Fix show_mem() for discontigmem show_mem() was assuming incorrectly that the mem_map for any node started at PFN 0. This is obviously wrong; fix it to take account of node_start_pfn.
