Merge branches 'acpi-fan', 'acpi-ec', 'acpi-drivers' and 'acpi-osl'

* acpi-fan:
  ACPI / fan: Fix error reading cur_state

* acpi-ec:
  ACPI / EC: Fix unused function warning when CONFIG_PM_SLEEP=n

* acpi-drivers:
  ACPI / PAD: don't register acpi_pad driver if running as Xen dom0

* acpi-osl:
  acpi_os_vprintf: Use printk_get_level() to avoid unnecessary KERN_CONT
