From 618dea44abf8e7766501ea94e9eda9308e1e4593 Mon Sep 17 00:00:00 2001 From: Michael Cree Date: Wed, 30 Nov 2011 08:01:40 -0500 Subject: alpha: add io{read,write}{16,32}be functions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit commit 25534eb7707821b796fd84f7115367e02f36aa60 upstream. These functions are used in some PCI drivers with big-endian MMIO space. Admittedly it is almost certain that no one this side of the Moon would use such a card in an Alpha but it does get us closer to being able to build allyesconfig or allmodconfig, and it enables the Debian default generic config to build.
