I have the same question as like above posted by Mr. Chirs. 
I had to google the subject to find what e-mail you were talking about
-- it was posted a year ago:

http://marc.info/?l=linuxppc-embedded&m=136572252330650&w=2

Next time please quote the e-mail if you're trying to revive a thread,
and keep the original poster on CC.

I've quoted it here:

Sorry for the bunch of emails, I'm working on some new stuff and running 
into issues.

For CONFIG_BOOKE it appears that DBCR0_ACTIVE_EVENTS includes DBCR0_ICMP 
but not DBCR0_BRT.  Is that just because none of the code paths 
currently using DBCR0_ACTIVE_EVENTS need to check DBCR0_BT?
Perhaps it was just an oversight.  I've CCed Dave Kleikamp and Torez
Smith, who added DBCR0_ACTIVE_EVENTS.
...and both of those e-mails bounced, so it may be that nobody who is
listening knows the answer.  Feel free to submit a patch that adds it,
with the changelog explaining why it should be included.
