[patch 1/3] Express relocatability of kernel on x86_64 in documentation

From: Bernhard Walle
Date: Sun Sep 09 2007 - 04:07:25 EST


This patch adapts the Documentation/kdump/kdump.txt file to express the fact
that the x86_64 kernel is now also relocatable. This makes i386 and x86_64 now
behave the same, simplifying the documentation.
