  33  * Generic ptrace interface that exports the architecture specific regsets
  34  * using the corresponding NT_* types (which are also used in the core dump).
  35  * Please note that the NT_PRSTATUS note type in a core dump contains a full
  36  * 'struct elf_prstatus'. But the user_regset for NT_PRSTATUS contains just the
  37  * elf_gregset_t that is the pr_reg field of 'struct elf_prstatus'. For all the
  38  * other user_regset flavors, the user_regset layout and the ELF core dump note
  39  * payload are exactly the same layout.
  40  *
  41  * This interface usage is as follows:
  42  *      struct iovec iov = { buf, len};
  43  *
  44  *      ret = ptrace(PTRACE_GETREGSET/PTRACE_SETREGSET, pid, NT_XXX_TYPE, &iov);
  45  *
  46  * On the successful completion, iov.len will be updated by the kernel,
  47  * specifying how much the kernel has written/read to/from the user's iov.buf.
