   When I use the kernel built by "build.sh kernel=GENERIC" (the source is
   updated at March 31), I find dtrace(1) error which prints the following
   message.
   ========== NG result ==========
   # dtrace -n 'proc::: {}'
   dtrace: invalid probe specifier proc::: {}: "/usr/lib/dtrace/psinfo.d", line 46: failed to copy type of 'pr_arglen': Type information is in parent and unavailable
   ========== NG result ==========

I think this is a symptom of the overflow of CTF data in the kernel
when compiled with debug data enabled -- but if we omit debug data
then I think the functionality is substantially reduced.  Someone^TM
needs to find a way to fix the CTF overflow properly.
