[PATCH] PCI: Export pci_cfg_space_size

[PATCH] PCI: Export pci_cfg_space_size

[Benjamin Herrenschmidt]

The powerpc PCI code sets up the PCI tree without doing config space
accesses in most cases, from the firmware tree. However, it still wants
to call pci_cfg_space_size() under some conditions, thus it needs to
be made non-static (though I don't see a point to export it to modules).

Greg: I don't remember if I already sent you that patch or not, if not,
then heh, here it is :) The powerpc patch that requires this one will be
going next to the powerpc git tree and -mm, with a 2.6.16 target. Let me
know if there is any objection.

Paul: You need that for the new G5 support patch that I'm sending next.
