Message-ID: <20130307145918.29098.28670.stgit@k.asiapacific.hpqcorp.net> Date: Thu, 07 Mar 2013 22:59:20 +0800 From: Jingbai Ma <jingbai.ma@...com> To: mingo@...hat.com, kumagai-atsushi@....nes.nec.co.jp, ebiederm@...ssion.com, hpa@...or.com, yinghai@...nel.org, vgoyal@...hat.com Cc: kexec@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [RFC PATCH 5/5] crash dump bitmap: workaround for kernel 3.9-rc1 kdump issue Linux kernel 3.9-rc1 allows crashkernel above 4GB, but current kexec-tools doesn't support it yet. This patch is only a workaround to make kdump work again. This patch should be removed after kexec-tools 2.0.4 release.
