Unset LOCKDEP and TRACE_IRQFLAGS_SUPPORT

Totally understand your points. However, Xenomai has been in many
distribution, like Ubuntu. it is simply a kind of interest to get something
to work. I had been an embedded engineer for many years, ( but never dealt
with Linux or Linux kernel). There are many Realtime OSes out there, but
costs a bomb and for hobbyist like me would not spend money buying it.
Having said that, there are a few open realtime patches that make LInux to
be realtime, deterministic. To what level, I am going to test it out. That
is my intention. If you are interested, please have a look at
www.xenomia.org.

It has nothing to do with confidence, it is pure experiment, hobby.
However, I do appreciate sharing your opinions. When times, I will have the
answers.

The kernel I work is for Pandaboard. Hence NVidia will not in the picture.
