    Linus Torvalds authored
    Pull RISC-V updates from Paul Walmsley:
     "New features:
       - SECCOMP support
       - nommu support
       - SBI-less system support
       - M-Mode support
       - TLB flush optimizations
    
      Other improvements:
       - Pass the complete RISC-V ISA string supported by the CPU cores to
         userspace, rather than redacting parts of it in the kernel
       - Add platform DMA IP block data to the HiFive Unleashed board DT
         file
       - Add Makefile support for BZ2, LZ4, LZMA, LZO kernel image
         compression formats, in line with other architectures
    
      Cleanups:
       - Remove unnecessary PTE_PARENT_SIZE macro
       - Standardize include guard naming across arch/riscv"
