Merge branch 'acpi-resources'

* acpi-resources: (23 commits)
  Merge branch 'pci/host-generic' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci into acpi-resources
  x86/irq, ACPI: Implement ACPI driver to support IOAPIC hotplug
  ACPI: Add interfaces to parse IOAPIC ID for IOAPIC hotplug
  x86/PCI: Refine the way to release PCI IRQ resources
  x86/PCI/ACPI: Use common ACPI resource interfaces to simplify implementation
  x86/PCI: Fix the range check for IO resources
  PCI: Use common resource list management code instead of private implementation
  resources: Move struct resource_list_entry from ACPI into resource core
  ACPI: Introduce helper function acpi_dev_filter_resource_type()
  ACPI: Add field offset to struct resource_list_entry
  ACPI: Translate resource into master side address for bridge window resources
  ACPI: Return translation offset when parsing ACPI address space resources
  ACPI: Enforce stricter checks for address space descriptors
  ACPI: Set flag IORESOURCE_UNSET for unassigned resources
  ACPI: Normalize return value of resource parser functions
  ACPI: Fix a bug in parsing ACPI Memory24 resource
  ACPI: Add prefetch decoding to the address space parser
  ACPI: Move the window flag logic to the combined parser
  ACPI: Unify the parsing of address_space and ext_address_space
  ACPI: Let the parser return false for disabled resources
