Linus recently merged [1] the wrapper functions memdup_array_user() and

I am currently adding them to all places where (v)memdup_user() had been
used to copy arrays.
The wrapper is different to the wrapped functions only in that it might
return -EOVERFLOW. So this new error code might get pushed up to
userspace. I hope this is fine.

you want to take the s390 patch through the s390 tree.
I think this is fine via your tree.
Feel free to add

to patch 2 if the commit id is not yet final.
