SubjectRe: [PATCH] x86/AMD: Apply erratum 688 on machines without a BIOS fix

Patch does not compile.

I tried to add pci.h but did nothing.
I converted pci_read_config to pci_read_config_dword but again nothing.

To be honest I can't say. My brother's machine(s) has random crashes
from time to time. We suspect that this erratum is to blame. He must
have kept some information at least from one of those crashes but there
was no time to analyze them till now. Finding those logs on our disks
needs a big effort but it will be done! We are willing to discover the
trouble maker no matter what it takes. To do that the machine must be
stripped off from all cards and then put on quarantine. Then we can
connect it with a another machine with an RS-232 cable to see what is
wrong. After that we must test it on a different motherboard we have. I
think we have one with a BIOS from a different BIOS vendor. We will
surely inform you on this one as we can't do such a patch. So we will
focus on triggering this bug. One thing is sure, its BIOS has no
workaround for that erratum.
