           driver and make it export frequency domains information to user
           space via sysfs (Ionela Voinescu).

      Merge KASAN updates from Andrew Morton.
      
      This adds a new hardware tag-based mode to KASAN.  The new mode is
      similar to the existing software tag-based KASAN, but relies on arm64
      Memory Tagging Extension (MTE) to perform memory and pointer tagging
      (instead of shadow memory and compiler instrumentation).

      x86/split-lock: Avoid returning with interrupts enabled · e14fd4ba
      Andi Kleen authored
      When a split lock is detected always make sure to disable interrupts
      before returning from the trap handler.
      
      The kernel exit code assumes that all exits run with interrupts
      disabled, otherwise the SWAPGS sequence can race against interrupts and
      cause recursing page faults and later panics.
      
      The problem will only happen on CPUs with split lock disable
      functionality, so Icelake Server, Tiger Lake, Snow Ridge, Jacobsville.
      
      Fixes: ca4c6a98 ("x86/traps: Make interrupt enable/disable symmetric in C code")
      Fixes: bce9b042 ("x86/traps: Disable interrupts in exc_aligment_check()") # v5.8+

      parameters and also reworks and clarifies some of the existing sections,
      in particular: defines what a memory granule is, mentions quarantine,
      makes Kunit section more readable.
