Unfortunatelly your changes in fs/proc/proc_misc.c broke every arch that
still uses HZ=100 (e.g. UML), because there is no "times" field in task
struct.
See this part:

+       {
+               unsigned long idle = init_task.times.tms_utime
+                                    + init_task.times.tms_stime;

In order to get UML to compile again (and pretty much any other HZ=100 arch)
I need to apply this patch below:

 		len = sprintf(page,"%lu.%02lu %lu.%02lu\n",
 			(unsigned long) uptime,
