PTI appears to be a solution to an Intel-only (huge) problem. Handsets vendors are safe to ignore it for now.

I wouldn't dare say that yet, ARM is pushing an ARM64 KPTI patch: https://lkml.org/lkml/2017/12/6/306

On the other hand that says "I'd like to start thinking about getting this merged for 4.16.", which sounds like the kind of relaxed attitude one might expect for a mostly-hypothetical KASLR-bypass issue that nobody is really worried about, and unlike the surprising urgency around the Intel KPTI patches.

(On the other other hand, not all handsets are ARM - some use Intel Atom SoCs, and might or might not be affected by this.)
