Subject: [RFC] remove dead code from sys_parisc32.c
Date: Sun, 17 Aug 2008 04:41:51 +0200
Message-ID: <20080817024151.GA24129@lst.de>
Mime-Version: 1.0
Content-Type: text/plain; charset=us-ascii
To: linux-parisc@vger.kernel.org
Return-path: <linux-parisc-owner@vger.kernel.org>
List-ID: <linux-parisc.vger.kernel.org>
List-Id: linux-parisc.vger.kernel.org

Unless I'm totally missing something get_fd_set32/set_fd_set32 are
completely unused.
