We could just skip the spurious TLB flush to mitigate the regression.

Ok, this patch I will apply.

Cheers.

I still hope that arm64 fixes (maybe already fixed) their spurious TLB function, and I think we should rename it to make sure everybody understands it's local, but in the meantime this patch hides the regression and isn't wrong.

I'll look at it for 5.10.
