Now down to 18.

And one of those 18 is commit 10af6235e0d3 ("x86/mm: Implement PCID
based optimization: try to preserve old TLB entries using PCID"),
which I guess is where the problem might actually start showing up if
it is pcid.

I'll continue to bisect rather than just test "nopcid", because I want
to get that bisection result regardless.
