DTrace asm profiler for Mac OS X

[Vsevolod Tolstopyatov]

Hi,

Thank you for help!

This is my leftover from experimenting with kernel profiling support.
I've fixed this in place (same gist:
https://gist.github.com/qwwdfsad/8c72f6bbde1d9376bc2391c73a14025f) and
re-validated it again, everything looks good for me now.
