* acpi-enumeration:
  ACPI: remove unnecessary INIT_LIST_HEAD
  ACPI / platform: include missed header into acpi_platform.c
  platform / ACPI: Attach/detach ACPI PM during probe/remove/shutdown
  mmc: sdhci-acpi: add SDHCI ACPI driver
  ACPI: add SDHCI to ACPI platform devices
  ACPI / PNP: skip ACPI device nodes associated with physical nodes already
  i2c / ACPI: add ACPI enumeration support
  ACPI / platform: Initialize ACPI handles of platform devices in advance
  ACPI / driver core: Introduce struct acpi_dev_node and related macros
  ACPI: Allow ACPI handles of devices to be initialized in advance
  ACPI / resources: Use AE_CTRL_TERMINATE to terminate resources walks
  ACPI: Centralized processing of ACPI device resources
  ACPI / platform: Use common ACPI device resource parsing routines
  ACPI: Move device resources interpretation code from PNP to ACPI core
  ACPI / platform: use ACPI device name instead of _HID._UID
  ACPI: Add support for platform bus type
  ACPI / ia64: Export acpi_[un]register_gsi()
  ACPI / x86: Export acpi_[un]register_gsi()
  ACPI: Provide generic functions for matching ACPI device nodes
  driver core / ACPI: Move ACPI support to core device and driver types
