Subject: [RFC Patch 00/19] Improve ACPI resource parsing interfaces and data structures

During enabling ACPI based IOAPIC hotplug, Thomas noticed some issues
in ACPI resource parsing interfaces. So this is an effort to improve them.

Patch 1-12 improve ACPI resource parsing interfaces and also fixes some
bugs.

Patch 13-19 try to share the common data structure resource_list_entry
between PCI and ACPI. It may also be shared with PNP too.

The patchset is based on v3.19-rc3 and you may get it from:
https://github.com/jiangliu/linux.git acpires_v1

Jiang Liu (11):
  ACPI: Fix a bug in parsing ACPI Memroy24 resource
  ACPI: Normalize return value of resource parser functions
  ACPI: Set flag IORESOURCE_UNSET for unassigned resources
  ACPI: Enforce stricter checks for address space descriptors
  ACPI: Return translation offset when parsing ACPI address space
    resources
  ACPI: Translate resource into master side address for bridge window
    resources
  ACPI: Add field offset to struct resource_list_entry
  ACPI: Introduce helper function acpi_dev_filter_resource_type()
  resources: Move struct resource_list_entry from ACPI into resource
    core
  PCI: Use common resource list management code instead of private
    implementation
  x86/PCI/ACPI: Use common ACPI resource interfaces to simplify
    implementation

Thomas Gleixner (8):
  ACPI: Remove redundant check in function
    acpi_dev_resource_address_space()
  ACPI: Implement proper length checks for mem resources
  ACPI: Use the length check for io resources as well
  ACPI: Let the parser return false for disabled resources
  ACPI: Provide union for address_space64 and ext_address_space64
  ACPI: Unify the parsing of address_space and ext_address_space
  ACPI: Move the window flag logic to the combined parser
  ACPI: Add prefetch decoding to the address space parser
