Run "git log --oneline drivers/pci" and make yours match. In particular, capitalize the first word ("Add"). Same for the other PCI patches. I don't know the drivers/net convention, but please find and follow that as well.
This constant is used (with different names) in more than one driver, so move it to the PCI core.
The driver constants in *this* patch at least use the same name.

This actually *adds* PCI_STATUS_SIG_TARGET_ABORT, which is not in the driver definitions. At the very least that should be mentioned in the commit log.
Ideally the addition would be in its own patch so it's obvious and bisectable, but I see the problem -- the subsequent patches consolidate things that aren't really quite the same. One alternative would be to have preliminary patches that change the drivers individually so they all use this new mask, then do the consolidation afterwards.
There is pitifully little documentation about the use of include/uapi, but AFAICT that is for the user API, and this isn't part of that. I think this #define could go in include/linux/pci.h instead.
