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

[Jiang Liu <jiang.liu@linux.intel.com>]

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:

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
