function::user_ulong - Retrieves an unsigned long value stored in user space

addr
           the user space address to retrieve the unsigned long from

       Returns the unsigned long value from a given user space address. Returns zero when user space data is not
       accessible. Note that the size of the unsigned long depends on the architecture of the current user space
       task (for those architectures that support both 64/32 bit compat tasks).
