    Pull ACPICA updates from Rafael Wysocki:
     "Additional ACPICA material for v4.2-rc1
    
      This will update the ACPICA code in the kernel to upstream revision
      20150619 (a bug-fix release mostly including stable-candidate fixes)
      and restore an earlier ACPICA commit that had to be reverted due to a
      regression introduced by it (the regression is addressed by
      blacklisting the only known system affected by it to date).
    
      The only new feature added by this update is the support for
      overriding objects in the ACPI namespace and a new ACPI table that can
      be used for that called the Override System Definition Table (OSDT).
      That should allow us to "patch" the ACPI namespace built from
      incomplete or incorrect ACPI System Definition tables (DSDT, SSDT)
      during system startup without the need to provide replacements for all
      of those tables in the future.
    
      Specifics:
    
       - Fix system resume problems related to 32-bit and 64-bit versions of
         the Firmware ACPI Control Structure (FACS) in the firmare (Lv
         Zheng)
    
       - Fix double initialization of the FACS (Lv Zheng)
    
       - Add _CLS object processing code to ACPICA (Suravee Suthikulpanit)
    
       - Add support for the (currently missing) new GIC version field in
         the Multiple APIC Description Table (MADT) (Hanjun Guo)
    
       - Add support for overriding objects in the ACPI namespace to ACPICA
         and OSDT support (Lv Zheng, Bob Moore, Zhang Rui)
    
       - Updates related to the TCPA and TPM2 ACPI tables (Bob Moore)
    
       - Restore the commit modifying _REV to always return "2" (as required
         by ACPI 6) and add a blacklisting mechanism for systems that may be
         affected by that change (Rafael J Wysocki)
    
       - Assorted fixes and cleanups (Bob Moore, Lv Zheng, Sascha Wildner)"
