  Merge patch "riscv: stacktrace: convert arch_stack_walk() to noinstr" (2024-06-26 07:38:02 -0700)

----------------------------------------------------------------
RISC-V Fixes for 6.10-rc6

* A fix for vector load/store instruction decoding, which could result
  in reserved vector element length encodings decoding as valid vector
  instructions.
* Instruction patching now aggressively flushes the local instruction
  cache, to avoid situations where patching functions on the flush path
  results in torn instructions being fetched.
* A fix to prevent the stack walker from showing up as part of traces.
