From 613813e8985bb76bd27937bfa54faf9e9be95a52 Mon Sep 17 00:00:00 2001 From: Dave Hansen Date: Wed, 4 Jun 2014 16:07:27 -0700 Subject: [PATCH] mm: debug: make bad_range() output more usable and readable Nobody outputs memory addresses in decimal. PFNs are essentially addresses, and they're gibberish in decimal. Output them in hex. Also, add the nid and zone name to give a little more context to the message.
