    Subject[patch] reproducible athlon mce fix
    Hi all,


    After switching from 2.4.22 to 2.6.0-test9, I have received reproducible
    MCE non-fatal error check messages in my kernel log. (For example, one
    shows up right after my first scsi card init).

    From Dave Jones' patch here:

    http://lists.insecure.org/lists/linux-kernel/2003/Sep/7362.html

    and another message here:

    http://lkml.org/lkml/2003/10/7/214

    would seem to imply that Athlons don't like having their Bank 0 poked at,
    though that's what non-fatal.c does. Would it be correct to make sure
    that that non-fatal.c starts at bank 1, if it is an Athlon?

    Dave, is the following patch correct? Booted and tested, no ill effects
    so far ...
