spectre V2 warning on boot of SFW

Hey all

been busy upgrading those who are still on 17x and 18 x and i ran into a weird one. i believe it was on 17.5.15 MR15x, i accepted the 19.0.2 MR2 build 472 version it offered on firmware page. Upgrade was uneventful. On boot I get this message;

0.001201 Spewctre V2: WARNING unprivileged eBPF is enabled with eIBRS on. data leaks possible via Spectre v2 BHB attacks!

Then boots normally and works OK. 

any thoughts?
