Subject: [PATCH 0/7] PCI: Use default pcibios_enable_device()

Several architectures implement a simple pcibios_enable_device() that looks
like this:

  int pcibios_enable_device(struct pci_dev *dev, int mask)
  {
         return pci_enable_resources(dev, mask);
  }

This puts a weak version of that in the PCI core and removes the
corresponding implementations from the architectures.

s390 is slightly less trivial but the same general idea.

I'd like to do the same for all the other architectures, but some (arm,
cris, m68k, mips, unicore32, xtensa, and parts of sparc and tile) don't
seem to use pci_claim_resource(), so BAR resource r->parent pointers
probably aren't set, so I can't change them yet.

Bjorn Helgaas (7):
      PCI: Add "weak" generic pcibios_enable_device() implementation
      alpha/PCI: Use default pcibios_enable_device()
      microblaze/PCI: Use default pcibios_enable_device()
      sh/PCI: Use default pcibios_enable_device()
      sparc/PCI: Use default pcibios_enable_device() (Leon only)
      tile PCI RC: Use default pcibios_enable_device()
      s390/PCI: Use generic pci_enable_resources()
