From: Bjorn Helgaas <bhelgaas@google.com>

The original PCI error recovery functionality was for the powerpc-specific
IBM EEH feature.  PCIe subsequently added some similar features, including
AER and DPC, that can be used on any architecture.

We want the generic PCI core error handling support to work with all of
these features.  Driver error recovery callbacks should be independent of
which feature the platform provides.

Add the generic PCI core error recovery files to the powerpc EEH
MAINTAINERS entry so the powerpc folks will be copied on changes to the
generic PCI error handling strategy.

I really want to make sure the powerpc folks are plugged into any PCI core
error handling discussions.  Please let me know if there's a better way
than this patch, or if there are other people who should be added.

I think this patch is definitely a good idea.

Alongside this (whether you want to include it in your patch or not, Bjorn),
Sam Bobroff should replace myself as maintainer.  He's been very active in fixing,
reworking and reviewing in EEH land and will probably do a better job of keeping
his finger on the pulse of the generic PCI error handling code than I did.

Sounds good. Oliver, you want to be looped in as well ?

Sure, putting all of EEH on Sam is probably not a nice thing to do.

That's fine with me. You can add me or let me know if I should send a
patch.

I applied the following to for-linus for v4.19.  Russell, if you want
to be removed, let me know and I'll do that.

commit 3fed0e04026c
Author: Bjorn Helgaas <bhelgaas@google.com>
Date:   Wed Sep 12 11:55:26 2018 -0500

    MAINTAINERS: Update PPC contacts for PCI core error handling
    
    The original PCI error recovery functionality was for the powerpc-specific
    IBM EEH feature.  PCIe subsequently added some similar features, including
    AER and DPC, that can be used on any architecture.
    
    We want the generic PCI core error handling support to work with all of
    these features.  Driver error recovery callbacks should be independent of
    which feature the platform provides.
    
    Add the generic PCI core error recovery files to the powerpc EEH
    MAINTAINERS entry so the powerpc folks will be copied on changes to the
    generic PCI error handling strategy.
    
    Add Sam and Oliver as maintainers for this area.

Oliver's email address for kernel stuff is oohall@gmail.com, I think benh has been
CCing his IBM address.  But other than that,

Yeah this is a good option.

We powerpc folks also need to do a better job of keeping an eye on PCI
patches, I've asked more of us to subscribe to linux-pci.
