Great, just like Hans I have been watching the progress of that patch
closely. A fix for a regression on the Raspi CM4 also landed in the past
24 hours.

I assume you'll also get the patch "objtool: Fix objtool regression on
x32 systems"
(https://lore.kernel.org/all/165304401319.4207.18392602354110557584.tip-bot2@tip-bot2/

) today or tomorrow.

That leaves the following post-5.17 regressions on my list where no fix
is in sight yet:

* Laptop with Ryzen 4600H fails to resume video
https://lore.kernel.org/stable/2584945.lGaqSPkdTl@geek500.localdomain/
(doesn't look like it first, but this apparently is a post-5.17
regression, as the commit causing it was backported; note, the Laptop
has some other problems with suspend that make the first suspend fail;
Mario is working hard with the reporter to find a fix)

* dpaa2: TSO offload on lx2160a causes fatal exception in interrupt
https://bugzilla.kernel.org/show_bug.cgi?id=215886
Debugging is ongoing, there is a patch now, but it's not clear yet if it
helps.

* the netperf.Throughput_Mbps -18.0% regression that made it into mainline:
https://lore.kernel.org/lkml/20220420013526.GB14333@xsang-OptiPlex-9020/
Didn't follow that one closely, as you were active in the discussion
yourself.

HTH, Ciao, Thorsten
