Ok, fair enough - I've changed it to v2 as you suggest:

-               pr_info("Filling RSB on context switch\n");
+               pr_info("Spectre v2 mitigation: Filling RSB on context 
-               pr_info("Enabling Indirect Branch Prediction Barrier\n");
+               pr_info("Spectre v2 mitigation: Enabling Indirect Branch 
Prediction Barrier\n");
