* 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
