Subject: [PATCH 00/16] PCI: Re-factor 'pcibios_setup()'

Currently, all of the architectures implement their own 'pcibios_setup()'
routine.  Most of the implementations do nothing so this patch introduces
a generic (__weak) routine into PCI's core that can be used by all
architectures as a default.  If necessary, it can then be over-ridden by
architecture-specific code.

This series also cleans up 'pcibios_setup()' as necessary to consistently
use the "__init" section annotation.

Suggested by Bjorn Helgaas -

It looks as if there is a bug in the CRIS architecture's version of
'pcibios_setup()'.  It implements pcibios_setup() such that pci_setup()
doesn't look for any generic options.  I included the fix for this in this
series.  If this ends up not being correct - i.e. PCI support for CRIS
should be dropped - then that specific patch (which I included last in the
series) can be dropped.

Note: I do not have a cross-compile environment so I have only tested x86.
