Pull more ACPI updates from Rafael Wysocki: "This includes a couple of fixes needed after recent changes, two ACPI driver fixes (fan and "Processor Aggregator"), an update of the ACPI device properties handling code and a new MAINTAINERS entry for ACPI on ARM64. Specifics: - Fix an unused function warning that started to appear after recent changes in the ACPI EC driver (Eric Biggers). - Fix the KERN_CONT usage in acpi_os_vprintf() that has become (particularly) annoying recently (Joe Perches). - Fix the fan status checking in the ACPI fan driver to avoid returning incorrect error codes sometimes (Srinivas Pandruvada). - Fix the ACPI Processor Aggregator driver (PAD) to always let the special processor_aggregator driver from Xen take over when running as Xen dom0 (Juergen Gross). - Update the handling of reference device properties in ACPI by allowing empty rows ("holes") to appear in reference property lists (Mika Westerberg). - Add a new MAINTAINERS entry for ACPI on ARM64 (Lorenzo Pieralisi)" * tag 'acpi-extra-4.9-rc1' of git:// acpi_os_vprintf: Use printk_get_level() to avoid unnecessary KERN_CONT ACPI / PAD: don't register acpi_pad driver if running as Xen dom0 ACPI / property: Allow holes in reference properties MAINTAINERS: Add ARM64-specific ACPI maintainers entry ACPI / EC: Fix unused function warning when CONFIG_PM_SLEEP=n ACPI / fan: Fix error reading cur_state
