v1 -> v2:
	* Shorten the varaible names so that they looks more short.
	* Changelog adjustment so that they looks more meaningful.

v2 -> v3:
	* Rebase to 3.5.RC4

v3 -> v4:
	* Merge Yinghai's patches.

v3 -> v4:
	* Split patch for easy review.
	* Add function to retrieve the minimal alignment of p2p bridge. 

v4 -> v5:
	* Rebase to 3.5.RC7
	* Introduce weak function pcibios_window_alignment() to retrieve
	  I/O and memory alignment for P2P bridges.
	* Introduce pcibios_window_alignment() for ppc to override the
	  PCI function.
	* Add ppc_md.pcibios_window_alignment() for specific platform like
	  powernv can override ppc's pcibios_window_alignment().

v5 -> v6:
	* Refactor pcibios_window_alignment() so the platform-specific
	  implementation needn't return the default alignment according
	  to Bjorn's suggestion.
	* Simplify pbus_size_mem() according to Bjorn's suggestion: Just
	  check the platform required alignment at very end and adjust
	  the "min_align" if necessary.

v6 -> v7:
	* Change "type" to "b_res->flags & mask" while retrieving the
	  minimal alignment for memory window according to Ram's suggestion.
	* Refactor pbus_size_mem() according to Ram's suggestion.
	* ppc_md.pcibios_window_alignment returns 1 for those PCI bridges
	  behind PCI bridges so that PCI core will use default alignment
	  values.

Lu Yinghai(3):
  pci: change variable name for find_pci_host_bridge
  pci: argument pci_bus for find_pci_host_bridge
  pci: fiddle with conversion of pci and CPU address

Gavin Shan(5)
  pci: weak function returns alignment
  pci: resource assignment based on p2p alignment
  pci: refactor function pbus_size_mem
  ppc/pci: override pcibios_window_alignment
  ppc/pnv: I/O and memory alignment for p2p bridges

v7 -> v8:
	* Rebase to 3.6.RC2, which starts to use "struct resource" to represent
	  the range of PCI bus numbers that specific p2p bridge covers.
	* Define macros for the default alignment of P2P bars according to
	  Richard's comments.
