git bisect says this breaks the shm* testcase in ltp on (at least) s390:

# ./test.sh
tst_test.c:1558: TINFO: Timeout per run is 0h 00m 30s
shmat01.c:124: TPASS: shmat() succeeded to attach NULL address
shmat01.c:92: TFAIL: shmat() failed: EINVAL (22)
shmat01.c:92: TFAIL: shmat() failed: EINVAL (22)
shmat01.c:92: TFAIL: shmat() failed: EINVAL (22)

Summary:
passed 1
failed 3
broken 0
skipped 0
warnings 0

Can you take a look? Thanks!

reverting the above commit fixes the issue.

Thanks,
Sven
