Subject: [PATCH] sh: crash kernel resource fix
Date: Wed, 27 Aug 2008 09:15:43 +0000 [thread overview]
Message-ID: <20080827091543.9100.82819.sendpatchset@rx1.opensource.se> (raw)
From: Magnus Damm <damm@igel.co.jp>
The reserved crash kernel memory range is currently missing from
/proc/iomem. crashk_res is mistakenly setup after __add_active_range().
Reorder things to make sure the resource shows up in /proc/iomem.
