Subject: [PATCH v1 0/4] Add uprobes support for LoongArch

v1:
  -- Split the RFC patch #2 into two patches
  -- Use larch_insn_gen_break() to generate break insns
     for kprobes and uprobes
  -- Pass around instruction word instead of union for
     insns_not_supported(), insns_need_simulation() and
     arch_simulate_insn() to avoid type conversion for callers
  -- Add a simple test case for uprobes in the commit message

Tiezhu Yang (4):
  LoongArch: Move three functions from kprobes.c to inst.h
  LoongArch: Add larch_insn_gen_break() to generate break insns
  LoongArch: Use larch_insn_gen_break() for kprobes
  LoongArch: Add uprobes support
