Subject: Add product identifying information to VMCOREINFO
Patch-mainline: Never, SUSE-specific
References: bsc#1123015

Since SUSE kernels sometimes backport patches that change the structures
required to save a dump file using makedumpfile, it is necessary to recognize
such a patched kernel from a vanilla kernel in the kdump environment. The
VMCOREINFO note is perfect for this purpose.
