Compilation [against 2.6.20.20] fails with

buildfarm linux-2.6.20 # make
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h

conflict

@kernel/sched_fair.c
-const_debug unsigned int sysctl_sched_nr_latency __read_mostly = 20;
+const_debug unsigned int sysctl_sched_nr_latency = 20;

seems solve that issue but i'm not sure this is the right thing to do or 
not :)
