commit 7362042f3556528e9e9b1eb5ce8d7a3a6331476b upstream.
Below incompatibilities between Python2 and Python3 made lx-timerlist fail to run under Python3.
o xrange() is replaced by range() in Python3 o bytes and str are different types in Python3 o the return value of Inferior.read_memory() is memoryview object in Python3
akpm: cc stable so that older kernels are properly debuggable under newer Python.
