Just because it didn't crash doesn't mean it is right :-)

I'll go with your implementation which according to the instruction
manual is the right way.  This particular function doesn't really get
exercised with out the arch specific hardware or software single
stepping code, which is not a part of this series at the moment.

This fix and the other fix you asked about are both in kgdb-next which
feeds into linux-next, if you are ultimately ok with the changes, I'll
add an ack from you as well.

Hopefully there is enough time to get the kdb shape for the next kernel
merge window.
