Hi again Ben.  You're right.

It could be nice though to have some mechanism to get from
a pci_resource_start/end that could be emitted via %pa
without an intermediate or casting like
(unsigned long long)pci_resource_<foo>(struct resource *)

There are at least a few dozen uses of dmesg/seq_printf with
%llx or %lx and (some_cast)pci_resource_<foo> that could be
converted.
