Merge branch 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6
* 'linux-next' of git://git.kernel.org/pub/scm/linux/kernel/git/jbarnes/pci-2.6: (41 commits) PCI: fix pci_ioremap_bar() on s390 PCI: fix AER capability check PCI: use pci_find_ext_capability everywhere PCI: remove #ifdef DEBUG around dev_dbg call PCI hotplug: fix get_##name return value problem PCI: document the pcie_aspm kernel parameter PCI: introduce an pci_ioremap(pdev, barnr) function powerpc/PCI: Add legacy PCI access via sysfs PCI: Add ability to mmap legacy_io on some platforms PCI: probing debug message uniformization PCI: support PCIe ARI capability PCI: centralize the capabilities code in probe.c PCI: centralize the capabilities code in pci-sysfs.c PCI: fix 64-vbit prefetchable memory resource BARs PCI: replace cfg space size (256/4096) by macros. PCI: use resource_size() everywhere. PCI: use same arg names in PCI_VDEVICE comment PCI hotplug: rpaphp: make debug var unique PCI: use %pF instead of print_fn_descriptor_symbol() in quirks.c PCI: fix hotplug get_##name return value problem ...
