    Pull arm64 updates from Catalin Marinas:
     "Mostly refactoring/clean-up:
    
       - CPU ops and PSCI (Power State Coordination Interface) refactoring
         following the merging of the arm64 ACPI support, together with
         handling of Trusted (secure) OS instances
    
       - Using fixmap for permanent FDT mapping, removing the initial dtb
         placement requirements (within 512MB from the start of the kernel
         image).  This required moving the FDT self reservation out of the
         memreserve processing
    
       - Idmap (1:1 mapping used for MMU on/off) handling clean-up
    
       - Removing flush_cache_all() - not safe on ARM unless the MMU is off.
         Last stages of CPU power down/up are handled by firmware already
    
       - "Alternatives" (run-time code patching) refactoring and support for
         immediate branch patching, GICv3 CPU interface access
    
       - User faults handling clean-up
    
      And some fixes:
    
       - Fix for VDSO building with brok...
