You should get either

[    0.000000] Kernel/User page tables isolation: enabled
or
[    0.000000] Kernel/User page tables isolation: disabled

Search with dmesg | less it's about two pages down for me,

$ uname -a
Linux debian 4.9.0-5-amd64 #1 SMP Debian 4.9.65-3+deb9u2 (2018-01-04) 
x86_64 GNU/Linux
