C calls to syscall like 'syscall(351, 1, 2, 3, 4, 5, 6);' resulted in
the following ftrace: 'sys_enter: NR 351 (1, 2, 3, 4, 5, 5)'.
This is because the syscall function failed to copy the 6th argument
into the appropriate register. In combination with the function calling
convention this meant that the 5th argument was repeated into the 6th.
