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.
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.
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
