Sorry for the sloppiness. :(

In the future, do you have a better suggestion on how to do large
sweeps on code for hardware that one might not own? Is there an
easier way other than setting up a cross-compiler environment?

Subject: [PATCH] remove rpaphp 'address_read_file'
From: Alex Chiang <achiang@hp.com>

Physical pci_slot removed ->get_address methods from individual
PCI hotplug drivers, but overlooked rpaphp, causing build errors.

Remove rpaphp's 'address_read_file' as well.
