Merge tag 'acpi-part2-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more ACPI updates from Rafael Wysocki: "These are mostly fixes and cleanups, a few new quirks, a couple of updates related to the handling of ACPI tables and ACPICA copyrights refreshment. Specifics: - Update the ACPICA kernel code to upstream revision 20180105 including: * Assorted fixes (Jung-uk Kim) * Support for X32 ABI compilation (Anuj Mittal) * Update of ACPICA copyrights to 2018 (Bob Moore) - Prepare for future modifications to avoid executing the _STA control method too early (Hans de Goede) - Make the processor performance control library code ignore _PPC notifications if they cannot be handled and fix up the C1 idle state definition when it is used as a fallback state (Chen Yu, Yazen Ghannam) - Make it possible to use the SPCR table on x86 and to replace the original IORT table with a new one from initrd (Prarit Bhargava, Shunyong Yang) - Add battery-related quirks for Asus UX360UA and UX410UAK and add quirks for table parsing on Dell XPS 9570 and Precision M5530 (Kai Heng Feng) - Address static checker warnings in the CPPC code (Gustavo Silva) - Avoid printing a raw pointer to the kernel log in the smart battery driver (Greg Kroah-Hartman)" * tag 'acpi-part2-4.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI: sbshc: remove raw pointer from printk() message ACPI: SPCR: Make SPCR available to x86 ACPI / CPPC: Use 64-bit arithmetic instead of 32-bit ACPI / tables: Add IORT to injectable table list ACPI / bus: Parse tables as term_list for Dell XPS 9570 and Precision M5530 ACPICA: Update version to 20180105 ACPICA: All acpica: Update copyrights to 2018 ACPI / processor: Set default C1 idle state description ACPI / battery: Add quirk for Asus UX360UA and UX410UAK ACPI: processor_perflib: Do not send _PPC change notification if not ready ACPI / scan: Use acpi_bus_get_status() to initialize ACPI_TYPE_DEVICE devs ACPI / bus: Do not call _STA on battery devices with unmet dependencies PCI: acpiphp_ibm: prepare for acpi_get_object_info() no longer returning status ACPI: export acpi_bus_get_status_handle() ACPICA: Add a missing pair of parentheses ACPICA: Prefer ACPI_TO_POINTER() over ACPI_ADD_PTR() ACPICA: Avoid NULL pointer arithmetic ACPICA: Linux: add support for X32 ABI compilation ACPI / video: Use true for boolean value
