Re: -rt doesn't compile for UML

so you can define irqs_off_flags to always-0 and you should be able
to get pretty good traces still. It should have no functional
impact.

OK, managed to make it compile, but then something goes wrong in
tracer_alloc_bootmem().

try with a lower MAX_TRACE first - 1 million entries (default) uses up
like 32 MB of RAM per CPU, that might be quite a bit and your UML image
might not be able to take that.

also, you can do a s/trace_alloc_bootmem/alloc_bootmem - the
alloc-bootmem wrapping was only done to get the tracer boot with really
ridiculously high MAX_TRACE.
