  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.
