No. This will not work. The PKU feature flag is bit 30. That is 2^30

the tests into PKU and non PKU tests. For PKU tests I may need to change
the bump frequency (in ac_test_bump_one) to much higher value. Right now,
it is 1. Let me try that,

The simplest way to cut on tests, which is actually similar to this patch, would be:

- do not try all combinations of PTE access bits when reserved bits are set

- do not try combinations with more than one reserved bit set
