Unless the system becomes an insane typewriter :)

Well, for us the situation is as following: Renesas requested XEN 4.12 for the next release of their virtualization package. And they employ KPTI enabled kernel in the BSP.
That reveals another critical issue for us, in addition to Set/Way issue and possible performance drops/irq latency raise due to specter mitigation measures.
I'm not sure if this is sufficient a justification to make it the release blocker, but we are up to this stuff.
