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