I just downloaded the 4.7.3 kernel and tried to import the 4.7.2 settings with the command "make oldconfig ../linux-4.7.2/.config". This doesn't work with the 4.7.3 version kernel, or at least not as I expect. I expect it to update the 4.7.3 configuration using the values in the config file specified. Instead I think it runs "make config", prompting for input of every single value on the command line. I'm not entirely certain the behaviour I expected is what was intended, for I'm fairly new at compiling kernels. It did however work with the 4.7.2 version, and now not anymore.
