Thanks.

For whatever reason it the dev debug symbols aren't available for the official 
Kernel:Stable branch,

        
http://software.opensuse.org/package/kernel-default-debuginfo?search_term=kernel-default-debuginfo

unlike for the release 4.1.x kernel.

But there is this from an unofficial repo

        
https://build.opensuse.org/package/binaries/hardware:nvdimm/kernel-default?repository=openSUSE_Leap_42.1

I'm not sure if that's good enough.  Anyway if I directly install that one

        
http://download.opensuse.org/repositories/hardware:/nvdimm/openSUSE_Leap_42.1/x86_64/kernel-default-debuginfo-4.7.0-5.1.x86_64.rpm

Then

        rpm -ql kernel-default-debuginfo | grep linux
                /usr/lib/debug/boot/vmlinux-4.7.0-5-default.debug

        addr2line -e /usr/lib/debug/boot/vmlinux-4.7.0-5-default.debug 
ffffffff81f6374c
                
/usr/src/debug/kernel-default-4.7.0/linux-4.7/linux-obj/../arch/x86/mm/numa_emulation.c:444
