Heiko, do you want a Signed-off-by or a Reported-by? Either one works
for me.

On a s390 z14 LAR with 2 cpus about stalls about 3% of the time while
loading the s390_trng.ko module.
Add a reschedule point to the loop that waits for modules to complete
loading.
Reported-by: Heiko Carstens <[email protected]>
Fixes: linux-next commit f9a75c1d717f ("modules: Only return -EEXIST for modules
that have finished loading")
