Most of the glue above can be deleted if you just accept to use kbuild when
building modules.
So to compile your module use a simple Makefile:
obj-m := mymodule.o

Then to compile the module use:
make -C path/to/kernel/src M=`pwd`

And to install it use:
make -C path/to/kernel/src M=`pwd` modules_install

And to clean up in the directory where the module is being compiled:
make -C path/to/kernel/src M=`pwd` clean
