Subject: arch/um/kernel/ptrace.c: remove dead PROC_MM
From: Christoph Egger <siccegge@cs.fau.de>

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.
