Well, the mce.c is not involved anymore. So if it we are piggybacking
on the native MCE handling routines - those routines (do_machine_check)
won't deliever the data to your driver anymore? B/c the do_machine_check
is doing mce_log which spools data. But your driver is using a different
system to de-spool the data - and it does not use the mcelog structure
array.

I've no idea what you mean here. Could you elaborate please?
