Linus Torvalds c013632192 2nd set of arm64 updates for 4.16: 
Spectre v1 mitigation:
 - back-end version of array_index_mask_nospec()
 - masking of the syscall number to restrict speculation through the
   syscall table
 - masking of __user pointers prior to deference in uaccess routines
 
 Spectre v2 mitigation update:
 - using the new firmware SMC calling convention specification update
 - removing the current PSCI GET_VERSION firmware call mitigation as
   vendors are deploying new SMCCC-capable firmware
 - additional branch predictor hardening for synchronous exceptions and
   interrupts while in user mode
 
 Meltdown v3 mitigation update for Cavium Thunder X: unaffected but
 hardware erratum gets in the way. The kernel now starts with the page
 tables mapped as global and switches to non-global if kpti needs to be
 enabled.
 
 Other:
 - Theoretical trylock bug fixed

Pull more arm64 updates from Catalin Marinas:
 "As I mentioned in the last pull request, there's a second batch of
  security updates for arm64 with mitigations for Spectre/v1 and an
  improved one for Spectre/v2 (via a newly defined firmware interface
  API).

  Spectre v1 mitigation:

   - back-end version of array_index_mask_nospec()

   - masking of the syscall number to restrict speculation through the
     syscall table

   - masking of __user pointers prior to deference in uaccess routines

  Spectre v2 mitigation update:

   - using the new firmware SMC calling convention specification update

   - removing the current PSCI GET_VERSION firmware call mitigation as
     vendors are deploying new SMCCC-capable firmware

   - additional branch predictor hardening for synchronous exceptions
     and interrupts while in user mode

  Meltdown v3 mitigation update:

    - Cavium Thunder X is unaffected but a hardware erratum gets in the
      way. The kernel now starts with the page tables mapped as global
      and switches to non-global if kpti needs to be enabled.
