I wonder if there's a way to use a common helper function to do this.  

Yes, this small bit of logic is duplicated all over the place. I'll see
if I can come up with some reasonable helpers for that.

Here is an attempt at doing this:

 - Introduce some helpers

   https://github.com/MISL-EBU-System-SW/mainline-public/commit/55543d2050d9aa3abe297569be830bde8680e1e9

 - Use them in drivers/pci/access.c

   https://github.com/MISL-EBU-System-SW/mainline-public/commit/ce6158d5c6a039e0cddf5ee6840dadeb46c5fc4b

 - Use them in PCI host controller drivers

   https://github.com/MISL-EBU-System-SW/mainline-public/commit/df4d0b5272ea3b4c3226c96466e5360c5a89253f

I'm not a big fan of the naming though. Let me know what you think, if
you think it's worth it, I'll submit the patches.

Note: the whole thing is compile-tested only for now.

Best regards,

Thomas
