Ok, I'm applying it, after fixing 'perf test unwind', 'perf top --call-graph dwarf'
and 'perf trace --call-graph dwarf', but I have one question, is the
scenario where we collect on a x86_64 machine and want to do analysis on
a ARM64 or x86-32 machine supported? This should be the odd case now,
but from a quick look I couldn't see this as being supported, is that
true or I was just lazy not to have tried this?
