Merge tag 'acpi-extra-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more ACPI updates from Rafael Wysocki:
 "Here are new versions of two ACPICA changes that were deferred
  previously due to a problem they had introduced, two cleanups on top
  of them and the removal of a useless warning message from the ACPI
  core.

  Specifics:

   - Move some Linux-specific functionality to upstream ACPICA and
     update the in-kernel users of it accordingly (Lv Zheng)

   - Drop a useless warning (triggered by the lack of an optional
     object) from the ACPI namespace scanning code (Zhang Rui)"

* tag 'acpi-extra-4.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  ACPI / osl: Remove deprecated acpi_get_table_with_size()/early_acpi_os_unmap_memory()
  ACPI / osl: Remove acpi_get_table_with_size()/early_acpi_os_unmap_memory() users
  ACPICA: Tables: Allow FADT to be customized with virtual address
  ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel
  ACPI: do not warn if _BQC does not exist
