CentOS - Mar 2016 - no kernel-debuginfo or source RPM for kernel 3.18.21-17

I'm trying to debug what I believe to be a kernel bug
(https://lists.centos.org/pipermail/centos-devel/2016-March/014463.html)
and I'm trying to set up systemtap for that.

I'm trying to set up systemtap on kernel 3.18.21-17.el6.x86_64 (Xen
4.4.3-10.el6) and it requires the kernel-debuginfo package, however I
cannot find anywhere package
kernel-debuginfo-3.18.21-17.el6.x86_64.rpm. In addition, I cannot find
anywhere the kernel source RPM in order to build the debuginfo RPM.

Should these packages be available in the first place? Am I missing something?

The xen kernel does not provide debuginfo.  The spec file initially came
from the elrepo repository, though it has been modified.  I don't think
any of the elrepo kernels build debuginfo files.

There is a newer kernel available now:

http://mirror.centos.org/centos/6/virt/x86_64/xen-44/kernel-3.18.25-18.el6.x86_64.rpm

In this case is the kernel source RPM publicly available then?
