Merge branches 'acpi-pci', 'acpi-misc' and 'acpi-tools' 

* acpi-pci:
  ACPI,PCI,IRQ: remove SCI penalize function
  ACPI,PCI,IRQ: remove redundant code in acpi_irq_penalty_init()
  ACPI,PCI,IRQ: reduce static IRQ array size to 16
  ACPI,PCI,IRQ: reduce resource requirements

* acpi-misc:
  ACPI / sysfs: fix error code in get_status()
  ACPI / device_sysfs: Clean up checkpatch errors
  ACPI / device_sysfs: Change _SUN and _STA show functions error return to EIO
  ACPI / device_sysfs: Add sysfs support for _HRV hardware revision
  arm64: defconfig: Enable ACPI
  ACPI / ARM64: Remove EXPERT dependency for ACPI on ARM64
  ACPI / ARM64: Don't enable ACPI by default on ARM64
  acer-wmi: Use acpi_dev_found()
  eeepc-wmi: Use acpi_dev_found()
  ACPI / utils: Rename acpi_dev_present()

* acpi-tools:
  tools/power/acpi: close file only if it is open
