Rewrite the logic in a way that it would be more resilient of code changes, by moving the source ID count to an enum and make the offset calculus more explicit. Such change was inspired on a patch from Jonathan Cameron splitting the logic to get the CPER address on a separate function, as this will be needed to support generic error injection. Signed-off-by: Mauro Carvalho Chehab --- 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.
