------------------------------------------------------ From: Peng Liu liupeng17@lenovo.com Subject: scripts/gdb: fix lx-timerlist for Python3 Date: Tue, 21 Mar 2023 14:19:29 +0800

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.
