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. Signed-off-by: Mauro Carvalho Chehab Reviewed-by: Jonathan Cameron --- Chenges from v10: - Some changes got moved to the previous patch. Changes from v8: - Non-rename/cleanup changes merged altogether; - source ID is now more generic, defined per guest target. That should make easier to add support for 86.
