+Subject: [PATCH] alpha: add io{read,write}{16,32}be functions
+Date: Wed, 30 Nov 2011 21:01:40 +1300
+Message-Id: <1322640100-14534-1-git-send-email-mcree@orcon.net.nz>
+
+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.
