ok so let me confirm. you would like to see renaming but that should 
happen right in patch1.
and then move all the error reporting to pcie_err.c
is that correct ?


besides, I am thinking to move
pci_do_recovery and removing everything from include/linux/pci.h  (which 
you suggested already)
but along with that....following defines will move in driver/pci/pci.h

#define PCI_ERR_AER_NONFATAL           0
#define PCI_ERR_AER_FATAL              1
#define PCI_ERR_AER_CORRECTABLE        2
#define PCI_ERR_DPC_NONFATAL           4

because, error codes have to be unified at one place.

will work on this and post the patch-set soon.

Oza.
