Although not specific to the question asked, but just an observation I have made, when using 'make oldconfig', copying the current '.config' to the directory containing the sources for the new kernel is not required, provided 'make install' was used to install the previous kernel, which would have put the config file into the boot directory. 'make oldconfig' uses the config file for the old kernel found in the '/boot' directory to generate a new '.config' file.
