There could be several sources with the same notification type, which is dependent of the way each architecture maps notifications. Right now, build_ghes_v2() hardcodes a 1:1 mapping between such fields. Move it to two independent parameters, allowing the caller function to fill both.

It is also badly named, as the offset actually used is the address where the CPER data starts, and not the beginning of the error source. Move the logic which calculates such offset to a separate function, in preparation for a patch that will be changing the logic to calculate it from the HEST table. While here, properly name the variable which stores the cper address.
