[Bug tapsets/11710] New: on s390x, all nd_syscall probes fail

[dsmith at redhat dot com]

Similar to bug #11701, on s390x I get wrong values for arguments using the
nd_syscall tapset.  For example:

# stap -e 'probe nd_syscall.open { println(argstr) }' -c 'cat /dev/null'
NULL, O_RDONLY
NULL, O_RDONLY
"", O_RDONLY|O_APPEND|O_DIRECTORY|O_LARGEFILE|O_NOCTTY|O_NOFOLLOW|O_NONBLOCK
"", O_RDONLY|O_APPEND|O_DIRECTORY|O_LARGEFILE|O_NOCTTY|O_NOFOLLOW|O_NONBLOCK
"en_US.utf8",
O_RDONLY|O_APPEND|O_CREAT|O_DIRECTORY|O_EXCL|O_LARGEFILE|O_NOFOLLOW|O_NONBLOCK,
01777777777777740706360
"en_US.utf8",
O_RDONLY|O_APPEND|O_CREAT|O_DIRECTORY|O_EXCL|O_LARGEFILE|O_NOFOLLOW|O_NONBLOCK,
01777777777777740706360
NULL, O_RDONLY
NULL, O_RDONLY
