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