Hi, Christoph,
Please sign off this patch.
Thanks,

Subject: [PATCH] m32r: use generic sys_pipe
Date: Fri, 09 May 2008 14:44:02 +0200
> m32r can use the generic sys_pipe implementation.
>
> The current sys_pipe implementation on m32r only differes from the
> generic one by passing a lot of additional unused registers to sys_pipe.
