Anil,

This set definitely improves things.  My timings from last week must
have been off.  I think I may have still had the notify_die() call in
the fault path.  This week, I see a 35 nSec slowdown between with/without
KRPOBES.  Last week, I thought they were roughly equivalent.


Thanks,
Robin Holt
