[Bug general/4865] New: ftrace gets java.lang.ArrayIndexOutOfBoundsException error when tracing frysk

[rmoseley at redhat dot com]

When I activate frysk and try to trace it using ftrace I get the following
stacktrace:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 24

    Fixes bug #4865
    * LinuxIa32Syscall.java (unknownIpcSubSyscall): New static field.
    (unknownSocketSubSyscall): Likewise.
    (ipcSubcallList): Add unknown numbers, including zero.
    (syscallByNum): Bounds check socketSubcallList and ipcSubcallList
    arrays before returning possible unknown subsyscall.
