[PATCH v3 0/6] Add uprobes support for LoongArch

[Tiezhu Yang]

v3:
  -- Check atomic instructions in insns_not_supported()
  -- Remove five DIE_* definitions in kdebug.h

v2:
  -- Move the functions to inst.c in patch #1
  -- Pass around union for insns_not_supported(),
     insns_need_simulation() and arch_simulate_insn()

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

  LoongArch: Move three functions from kprobes.c to inst.c
  LoongArch: Add larch_insn_gen_break() to generate break insns
  LoongArch: Use larch_insn_gen_break() for kprobes
