* Generic ptrace interface that exports the architecture specific regsets

* 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.
