      由 Linus Torvalds 提交于 
      Pull arm64 updates from Catalin Marinas:
 "Apart from the core arm64 and perf changes, the Spectre v4 mitigation
  touches the arm KVM code and the ACPI PPTT support touches drivers/
  (acpi and cacheinfo). I should have the maintainers' acks in place.

  Summary:

   - Spectre v4 mitigation (Speculative Store Bypass Disable) support
     for arm64 using SMC firmware call to set a hardware chicken bit

   - ACPI PPTT (Processor Properties Topology Table) parsing support and
     enable the feature for arm64

   - Report signal frame size to user via auxv (AT_MINSIGSTKSZ). The
     primary motivation is Scalable Vector Extensions which requires
     more space on the signal frame than the currently defined
     MINSIGSTKSZ

   - ARM perf patches: allow building arm-cci as module, demote
     dev_warn() to dev_dbg() in arm-ccn event_init(), miscellaneous
     cleanups

   - cmpwait() WFE optimisation to avoid some spurious wakeups

   - L1_CACHE_BYTES reverted back to 64 (for performance reasons that
     have to do with some network allocations) while keeping
     ARCH_DMA_MINALIGN to 128. cache_line_size() returns the actual
     hardware Cache Writeback Granule

   - Turn LSE atomics on by default in Kconfig

   - Kernel fault reporting tidying

   - Some #include and miscellaneous cleanups"

      由 Linus Torvalds 提交于 
      Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v4.18 development cycle.

  Core changes:

   - We have killed off VLA from the core library and all drivers.

     The background should be clear for everyone at this point:

        https://lwn.net/Articles/749064/

     Also I just don't like VLA's, kernel developers hate it when
     compilers do things behind their back. It's as simple as that.

     I'm sorry that they even slipped in to begin with. Kudos to Laura
     Abbott for exorcising them.

   - Support GPIO hogs in machines/board files.

  New drivers and chip support:

   - R-Car r8a77470 (RZ/G1C)

   - R-Car r8a77965 (M3-N)

   - R-Car r8a77990 (E3)

   - PCA953x driver improvements to accomodate more variants.

  Improvements and new features:

   - Support one interrupt per line on port A in the DesignWare dwapb
     driver.

  Misc:

   - Random cleanups, right header files in the drivers, some size
     optimizations etc"
