From 7399515d25066368707d804d90cc8d3976f313bc Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 10 Aug 2015 22:02:54 -0600 Subject: [PATCH] x86: Show the un-relocated IP address in exceptions When trying to figure out where an exception has occured, the relocated address is not a lot of help. Its value depends on various factors. Show the un-relocated IP as well. This can be looked up in System.map directly.
