right. I mentioned this in a pervious mail that we weren't handling
compat syscalls. That said, the pervious syscall tracer also had the
same issue, so we haven't taken a step back. I guess we need to convert
some of the compat layer to use the DEFINE_SYSCALL() macros. Also, there
are a number of 64-bit syscalls that don't use DEFINE_SYSCALL either.
Those need to converted as well. The patchset I submitted converted a
couple of them....
thanks,
