From 9b013c2820c409ff84871e55e407ec2181782773 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Fri, 9 May 2008 14:44:02 +0200 Subject: [PATCH] m32r: use generic sys_pipe 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. Reviewed and tested by Hirokazu Takata.
