Linus Torvalds 0aebc6a440 arm64 updates for 4.16:
- Security mitigations:
   - variant 2: invalidating the branch predictor with a call to secure firmware
   - variant 3: implementing KPTI for arm64
 
 - 52-bit physical address support for arm64 (ARMv8.2)
 
 - arm64 support for RAS (firmware first only) and SDEI (software
   delegated exception interface; allows firmware to inject a RAS error
   into the OS)
 
 - Perf support for the ARM DynamIQ Shared Unit PMU
 
 - CPUID and HWCAP bits updated for new floating point multiplication
   instructions in ARMv8.4
 
 - Removing some virtual memory layout printks during boot
 
 - Fix initial page table creation to cope with larger than 32M kernel
   images when 16K pages are enabled

Pull arm64 updates from Catalin Marinas:
 "The main theme of this pull request is security covering variants 2
  and 3 for arm64. I expect to send additional patches next week
  covering an improved firmware interface (requires firmware changes)
  for variant 2 and way for KPTI to be disabled on unaffected CPUs
  (Cavium's ThunderX doesn't work properly with KPTI enabled because of
  a hardware erratum).

  Summary:

   - Security mitigations:
      - variant 2: invalidate the branch predictor with a call to
        secure firmware
      - variant 3: implement KPTI for arm64

   - 52-bit physical address support for arm64 (ARMv8.2)

   - arm64 support for RAS (firmware first only) and SDEI (software
     delegated exception interface; allows firmware to inject a RAS
     error into the OS)

   - perf support for the ARM DynamIQ Shared Unit PMU

   - CPUID and HWCAP bits updated for new floating point multiplication
     instructions in ARMv8.4

   - remove some virtual memory layout printks during boot

   - fix initial page table creation to cope with larger than 32M kernel
     images when 16K pages are enabled"
