[BK PATCH] PCI hotplug changes for 2.5.63

[Greg KH <greg@kroah.com>]

Hi,

Here's some patches that clean up the remove logic a lot for the PCI
hotplug drivers.  The main PCI patches were done by Russell King and
Christoph Hellwig, and then I went and cleaned up the PCI Hotplug
drivers a lot based on their changes.  I also fixed up some exit logic
in the IBM PCI hotplug driver, as it was a mess.

Scott, I modified the cPCI core in order to get it to build and link
properly again, but as I don't have the hardware to test it, you should
probably look over the change and see if I messed anything up or not.
Also, I think you are the last user of the pci_visit structure, make
sure you really need it, otherwise we can get rid of it entirely from
the PCI core.

Please pull from:  bk://kernel.bkbits.net/gregkh/linux/pci-2.5

thanks,

greg k-h

  [PATCH] CPCI core: remove unneeded visit device on unconfigure.
  
  The driver now links properly, but this is untested due to my
  lack of cPCI hardware.

  [PATCH] PCI: Make hot unplugging of PCI buses work
  
  Here's the updated patch:
  
  - Scott spotted a leak my handling of procfs wrt buses.
  - I've also killed pci_remove_device() entirely - it is now inlined.
  - After one of Alan's mails, I decided that pci_remove_behind_bridge()
    is a much better name than pci_remove_all_bus_devices()

  [PATCH] PCI: remove check_region abuse (and code duplication) from pci hp code
  
  We have a function pci_dev_driver() to check whether a pci_dev has an
  driver attached to it.  It's handling of legacy devices is a bit simpler
  than what the hotplug code did (duplicated in various places), but if
  that stuff is really needed the generic code should be updated.
