Ah, so the reason for this breakage is because lockdep was relying on
instruction_pointer.h, that just happened to be included in kernel.h
via trace_printk.h.

This is a separate issue, so it should be a separate patch. I'll add it
as patch 1 of this series.

Can you send me the config you used. This didn't trigger in my tests.

Thanks,
