Thanks for the fix.
I've tried this combination and it was fine, since whole kernel/trace/
directory is not compiled when !CONFIG_TRACING, but I missed the fact
that CONFIG_RING_BUFFER=y also enables kernel/trace/ which this ia64
.config exploited :( I'll add it to my set of configs.
Thanks again for the fix. It makes dependency clear.

I saw this on x86 as well, but yeah, it was a rare thing.
Thanks,
