Except that on x86 I don't see any __se_sys_* functions in kallsyms.
# grep _se_sys /proc/kallsyms
# grep _x64_sys /proc/kallsyms | head
ffffffff81032ae0 T __x64_sys_arch_prctl
ffffffff81033400 T __x64_sys_rt_sigreturn
ffffffff81036ea0 T __x64_sys_iopl
ffffffff810371d0 T __x64_sys_ioperm
ffffffff81039090 T __x64_sys_modify_ldt
ffffffff81039da0 T __x64_sys_mmap
ffffffff81045060 T __x64_sys_set_thread_area
ffffffff81045150 T __x64_sys_get_thread_area
ffffffff810aa450 T __x64_sys_set_tid_address
ffffffff810ad7c0 T __x64_sys_fork
I'd say leave the documentation alone.
