Message-ID: <20070319160218.GA27462@lst.de>
Date: Mon, 19 Mar 2007 17:02:18 +0100
From: Christoph Hellwig <hch@....de>
To: akpm@...l.org
Cc: linux-kernel@...r.kernel.org
Subject: [PATCH] move die notifier handling to common code
This patch moves the die notifier handling to common code. Previous
various architectures had exactly the same code for it. Note that
the new code is compiled unconditionally, this should be understood
as an appel to the other architecture maintainer to implement
support for it aswell (aka sprinkling a notify_die or two in the
proper place)
arm had a notifiy_die that did something totally different, I renamed
it to arm_notify_die as part of the patch and made it static to the
file it's declared and used at. avr32 used to pass slightly less
information through this interface and I brought it into line with
the other architectures.
