Hi Ilya,

Sorry for this taking so long, I'll probably take a closer look next week.
Overall, the s390 part looks good to me, but I wanted to check the x86
behavior once again (and perhaps figure out how to avoid introducing
another way to disable KMSAN).
Do you happen to have a Git repo with your patches somewhere?
