Subject: [patch 14/21] s390: use sys_pause for 31bit pause entry point
Date: Wed, 01 Oct 2008 10:33:31 +0200 [thread overview]
Message-ID: <20081001084128.764462323@de.ibm.com> (raw)
In-Reply-To: 20081001083317.782967473@de.ibm.com
[-- Attachment #1: 113-sys-pause.diff --]
[-- Type: text/plain, Size: 2929 bytes --]
From: Christoph Hellwig <hch@lst.de>
sys32_pause is a useless copy of the generic sys_pause.
(and it's certainly not there for old sparc32 binaries..)
