Naveen N. Rao e12d94f806 powerpc/xmon: Exclude all of xmon from ftrace
Exclude core xmon files from ftrace (along with an xmon xive helper
outside of xmon/) to minimize impact of ftrace while within xmon.

Before:
  /sys/kernel/debug/tracing# grep -ci xmon available_filter_functions
  26

After:
  /sys/kernel/debug/tracing# grep -ci xmon available_filter_functions
  0
