we got 12 regressions and 1 improvement results for efa7df3e3b so far.
(4 regressions are just similar to what we reported for 1111d46b5c).
by your patch, 6 of those regressions are fixed, others are not impacted.

below is a summary:

No. testsuite test status-on-efa7df3e3b fix-by-d8d7b1dae6 ?
=== ========= ==== ==================== ===================
(1) stress-ng numa regression NO
(2) pthread regression yes (on a Ice Lake server)
(3) pthread regression yes (on a Cascade Lake desktop)
(4) will-it-scale malloc1 regression NO
(5) page_fault1 improvement no (so still improvement)
(6) vm-scalability anon-w-seq-mt regression yes
(7) stream nr_threads=25% regression yes
(8) nr_threads=50% regression yes
(9) phoronix osbench.CreateThreads regression yes (on a Cascade Lake server)
(10) ramspeed.Add.Integer regression NO (and below 3, on a Coffee Lake desktop)
(11) ramspeed.Average.FloatingPoint regression NO
(12) ramspeed.Triad.Integer regression NO
(13) ramspeed.Average.Integer regression NO

below are details, for those regressions not fixed by d8d7b1dae6, attached
full comparison.
