I agree, its is just that drivers/acpi/apet/ghes.c has to do
#include ../../pci/pci.h


That's bad. I was just thinking about the DPC error code only. I didn't 
realize

AER error codes are being referenced from ghes.c.



but thats okay I think.  let me move error codes to drivers/pci/pci.h.


It is better if error codes move to include/linux/pci.h and keep them 
together.




The problem with moving them to include/linux/pci.h, it falls into 
global scope, besides

they have to be renamed to/prefixed with PCI_ERR_xxx

the use of AER_FATAL, DPC_FATAL etc.. is very limited in entire linux. 
and likely to be so.

I think moving them to drivers/pci/pci.h would be more restricted/local

let me make patch-set based on that, and see how it looks like. we can 
arrive at some consensus then.

can you keep this in drivers/pci.h and get rid of this file?


I thought about this, but if I keep it in drivers/pci.h,
then AER's defines have to be in that as well. (for unification)

and then all the dependent files who are using AER_FATAL such as
drivers/acpi/apei/ghees.c
have to go on including this drivers file which is odd way of doing 
it.


So I am not very sure about thissince AER_FATAL are in aer.h, I
have made dpc.h

I think we need a pci_find_service function that unifies these two.


Right now, find_xxx_service are in their respective file and exporting

which makes sense no less than having generic function.

If I have to change pci_find_service(, int service_name) then it

can you keep this in drivers/pci.h and get rid of this file?


I thought about this, but if I keep it in drivers/pci.h,
then AER's defines have to be in that as well. (for unification)

and then all the dependent files who are using AER_FATAL such as 
drivers/acpi/apei/ghees.c

have to go on including this drivers file which is odd way of doing it.

So I am not very sure about thissince AER_FATAL are in aer.h, I have 
made dpc.h

I think we need a pci_find_service function that unifies these two.
