  ACPI: SBS: Add ACPI_PROCFS around procfs handling code.
  ACPI: SBS: Add support for power_supply class (and sysfs)
  ACPI: SBS: Make SBS reads table-driven.
  ACPI: SBS: Simplify data structures in SBS
  ACPI: SBS: Split host controller (ACPI0001) from SBS driver (ACPI0002)
  ACPI: EC: Add new query handler to list head.
  ACPI: Add acpi_bus_generate_event4() function
  ACPI: Battery: add sysfs alarm
