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.
