Adding libdw DWARF post unwind support, which is part of elfutils-devel/libdw-dev package from version 0.158.
The new code is contained in unwin-libdw.c object, and implements unwind__get_entries unwind interface function.

Ok, thx!
Jiri, Arnaldo, Can you take the series for ARM and ARM64?
Wait: I thought you were going to add compat support for arm64? I haven't acked that patch yet, because it's lacking those changes.
The compat mode is supported by libdw and _should_ work in principle. I am following it up with Mark Wielaard on elfutils-devel. Cf. [1] for the discussion and [2] for the compat mode support in libdw.

So in summary the kernel changes should be fine (it works ok with libunwind), the problem lies somewhere in the libdw registers setup and usage for compat mode.
The 32-bit ARM patches look fine though.
Thx!
