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: (74 commits) PCI: make msi_free_irqs() to use msix_mask_irq() instead of open coded write PCI: Fix the NIU MSI-X problem in a better way PCI ASPM: remove get_root_port_link PCI ASPM: cleanup pcie_aspm_sanity_check PCI ASPM: remove has_switch field PCI ASPM: cleanup calc_Lx_latency PCI ASPM: cleanup pcie_aspm_get_cap_device PCI ASPM: cleanup clkpm checks PCI ASPM: cleanup __pcie_aspm_check_state_one PCI ASPM: cleanup initialization PCI ASPM: cleanup change input argument of aspm functions PCI ASPM: cleanup misc in struct pcie_link_state PCI ASPM: cleanup clkpm state in struct pcie_link_state PCI ASPM: cleanup latency field in struct pcie_link_state PCI ASPM: cleanup aspm state field in struct pcie_link_state PCI ASPM: fix typo in struct pcie_link_state PCI: drivers/pci/slot.c should depend on CONFIG_SYSFS PCI: remove redundant __msi_set_enable() PCI PM: consistently use type bool for wake enable variable x86/ACPI: Correct maximum allowed _CRS returned resources and warn if exceeded ...
