thanks again for the whole series.  I really appreciated to go through
this patch set and am sorry for that it took so long.  I have tested
only with some in-tree kmods and with kmods' testsuite modules (but only
on amd64) and could not find any major issue, only the minor things
reported.  I also did not test the kselftest or similar.

Kind regards,
Nicolas
