From 5a79859ae0f35d25c67a03e82bf0c80592f16a39 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Thu, 12 Feb 2015 13:08:27 +0100 Subject: s390: remove 31 bit support Remove the 31 bit support in order to reduce maintenance cost and effectively remove dead code. Since a couple of years there is no distribution left that comes with a 31 bit kernel. The 31 bit kernel also has been broken since more than a year before anybody noticed. In addition I added a removal warning to the kernel shown at ipl for 5 minutes: a960062e5826 ("s390: add 31 bit warning message") which let everybody know about the plan to remove 31 bit code. We didn't get any response. Given that the last 31 bit only machine was introduced in 1999 let's remove the code. Anybody with 31 bit user space code can still use the compat mode.
