i added tracehook support to Blackfin recently, so that covered all
the new functions here.  i just had to drop the handling of the
PTRACE_xxx things that common code already does.

when did you want to push through these updates ?  i was planning on
sending these ptrace() updates through the Blackfin tree as part of my
2.6.34 queue.  i'm guessing you didnt want this stuff in 2.6.33 ...
