function::user_ulong_error - Retrieves a 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. If the user space data is not
       accessible, an error will occur. 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).
