Subject: pci hotplug: fix rpaphp directory naming
From: Linas Vepstas <[EMAIL PROTECTED]>
Fix presentation of the slot number in the /sys/bus/pci/slots
directory to match that used in the majority of other drivers.

This patch implements exactly what you describe. Boot tested.
I assume you really mean it -- if so, then please review and
ack the patch !?
I have absolutely no clue if this breaks any existing IBM tools.
I'm pretty sure it doesn't ... but attention Mike Strosaker! does it?
