Linus Torvalds 6a0e20cd8c First set of RISC-V updates for v5.5-rc1
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
