From 7833e7c961612d3031c231596f8d71d0a9b45687 Mon Sep 17 00:00:00 2001 From: Christoph Egger Date: Mon, 9 Aug 2010 17:20:16 -0700 Subject: [PATCH] arch/um/kernel/ptrace.c: remove dead PROC_MM PROC_MM doesn't exist in Kconfig. Looking around it looks like a left-over from 2.6.0 or even 2.4 times, last mentioned in a fedora patch for 2.6.10. I believe it's time to get rid of that last tiny parts here that are still around.
