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)"
