How long does a backtrace take compared to the old code? I see you already care about the NMI. I guess it still takes too long for being called for oprofiles callgraph backtrace? Are there any ways how we can speed this up?
After initial performance problems (iirc lockdep added heavy use of the unwind routines), I had added creation of a binary lookup table (pretty new binutils can create it at build time), so performance shouldn't be that bad anymore.
