      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 broken ELF toolchains
      
         - Fix another case of init_mm.pgd usage for user mappings (during
           ASID roll-over broadcasting)
      
         - Fix for FPSIMD reloading after CPU hotplug
      
         - Fix for missing syscall trace exit
      
         - Workaround for .inst asm bug
      
         - Compat fix for switching the user tls tpidr_el0 register"

      Pull first batch of KVM updates from Paolo Bonzini:
       "The bulk of the changes here is for x86.  And for once it's not for
        silicon that no one owns: these are really new features for everyone.
      
        Details:
      
         - ARM:
              several features are in progress but missed the 4.2 deadline.
              So here is just a smattering of bug fixes, plus enabling the
              VFIO integration.
      
         - s390:
              Some fixes/refactorings/optimizations, plus support for 2GB
              pages.
      
         - x86:
              * host and guest support for marking kvmclock as a stable
                scheduler clock.
              * support for write combining.
              * support for system management mode, needed for secure boot in
                guests.
              * a bunch of cleanups required for the above
              * support for virtualized performance counters on AMD
              * legacy PCI device assignment is deprecated and defaults to "n"
                in Kconfig; VFIO replaces it
      
              On top of this there are also bug fixes and eager FPU context
              loading for FPU-heavy guests.
      
         - Common code:
              Support for multiple address spaces; for now it is used only for
              x86 SMM but the s390 folks also have plans"
      
      * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (124 commits)
