The unwind info for the Linux kernel does get included in the
core-dump (see Roland McGrath's work on this), but it is not available
via /proc. Note that in the future, it won't be necessary to do a
syscall. Instead, the kernel's unwind info will be available (to the
running process) via dl_iterate_phdr(). I'm not sure though how this
is supposed to be made accessible to programs such as gdb.
