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 ...
