Subject: [patch 1/3] Express relocatability of kernel on x86_64 in documentation
Content-Disposition: inline; filename=crashkernel-relocatable
Sender: linux-kernel-owner@vger.kernel.org
Content-Length: 3109
Lines: 84

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.
