Linus Torvalds 5289851171 arm64 updates for 4.20:
- Core mmu_gather changes which allow tracking the levels of page-table
   being cleared together with the arm64 low-level flushing routines
 
 - Support for the new ARMv8.5 PSTATE.SSBS bit which can be used to
   mitigate Spectre-v4 dynamically without trapping to EL3 firmware
 
 - Introduce COMPAT_SIGMINSTKSZ for use in compat_sys_sigaltstack
 
 - Optimise emulation of MRS instructions to ID_* registers on ARMv8.4
 
 - Support for Common Not Private (CnP) translations allowing threads of
   the same CPU to share the TLB entries
 
 - Accelerated crc32 routines
 
 - Move swapper_pg_dir to the rodata section
 
 - Trap WFI instruction executed in user space

Pull arm64 updates from Catalin Marinas:
 "Apart from some new arm64 features and clean-ups, this also contains
  the core mmu_gather changes for tracking the levels of the page table
  being cleared and a minor update to the generic
  compat_sys_sigaltstack() introducing COMPAT_SIGMINSKSZ.

  Summary:

   - Core mmu_gather changes which allow tracking the levels of
     page-table being cleared together with the arm64 low-level flushing
     routines

   - Support for the new ARMv8.5 PSTATE.SSBS bit which can be used to
     mitigate Spectre-v4 dynamically without trapping to EL3 firmware

   - Introduce COMPAT_SIGMINSTKSZ for use in compat_sys_sigaltstack

   - Optimise emulation of MRS instructions to ID_* registers on ARMv8.4

   - Support for Common Not Private (CnP) translations allowing threads
