[RFC] Get rid of all procfs stuff for PCI subsystem.

[RFC] Get rid of all procfs stuff for PCI subsystem.

[Stanley Wang]

Hi, Greg
When did I try to remove all procfs stuff from pci_hotplug_core.c,
I found I could only cut little codes off. So I suggest:
How about to get rid of all procfs stuff for PCI subsystem?
It could reduce about 700 lines codes from the kernel.
I think we could get all information from sysfs, right?
But it may break some user mode utilities.

What do you think about it?

Regards,
-Stan

But you cut out everything that was there, right?  There wasn't much.

If you look, a lot of it is now under a config option to just not enable
it at all, which helps out a lot.

Is there a plan to update pci-utils to work with sysfs?  lspci is a pretty
valuable debugging tool, it would be a shame to lose the use of it in 2.6.

I'm pretty sure it works without the /proc pci stuff already (well the
big tables in there, I think it still needs the individual pci device
entries.)

And yes, sysfs support would be nice, hint, hint, hint...  :)
