Here are a few changes to minimize calls to stop_machine() and
flush_icache_*() in the various text patching functions, as well as
to simplify the code.


Samuel Holland (7):
  riscv: jump_label: Batch icache maintenance
  riscv: jump_label: Simplify assembly syntax
  riscv: kprobes: Use patch_text_nosync() for insn slots
  riscv: Simplify text patching loops
  riscv: Pass patch_text() the length in bytes
  riscv: Use offset_in_page() in text patching functions
  riscv: Remove extra variable in patch_text_nosync()
