Basically this means that python (or some .so modules) passed an int or unsigned int as parameter 'cmd', we need to change it to unsigned long. The warning itself should be harmless to my best of knowledge, one can probably remove the printf in kernel source code as a workaround. By the way it seems to be a POSIX violation and we didn't seem to really use so wide cmd, but I have not yet verified everything myself.
