Requires: 24a0c654d7d6 ("PCI: Add for_each_pci_bridge() helper")

(My fault, I rebased that commit before sending it to Linus.)

These don't depend on anything in the PCI core, so they could go
either via my tree or the powerpc tree.  Since you acked this,
Michael, I corrected the SHA1 above and put these both on my pci/misc
branch.

If you pick them up, let me know and I'll drop them from my tree.
