FWIW, I had to port the SUSE's in-kernel DWARF unwinder which we drag
for a decade or so. It seems to be working correctly on the top of the
rewritten 4.9 stack unwinding. It needs a lot of polishing, though. And
it does not go beyond a single stack (e.g. from IRQ to process ctx) yet
(it never did).

Having the working DWARF unwinder, I am moving to DWARF generation for
asm in your tool now.
