    Andreas Schwab 提交于
    This fixes the following issues in ptrace:
    
    - when single stepping into the signal handler stop at the first insn of
      the handler
    - handle non-zero stkadj when accessing pc and sr in ptregs
    - correctly handle PT_SR in PTRACE_POKEUSR
    - report -EIO when trying to read unknown offset in PTRACE_PEEKUSR
    
    Additionally, the handling of the special case that PT_SR accesses a 16
    bit word instead of a 32 bit word has been moved into get_reg/put_reg.
