I've been playing with that. It completed after ~45secs. The linked
dmesg had also mmu_stress_test timed out but it completed here, too.
I had a timeout in access_tracking_perf_test and memslot_perf_test.

The box is very sluggish. LOCKDEP, KASAN and maybe UBSAN cause that. I
would say the commit in question is innocent.
