I don't see any "gcc -m" type of dependency generation pass happening
in this relatively simple Make system.
It happens with -MD, all the deps are stored in files like mm/.init-mm.o.cmd

You are thinking of kbuild. This is not kbuild. There are no such artifacts
being generated.
And so, without including an explicit header file dependency (at
least, that's the simplest way), changes to gup_test.h are not
detected.

Both the Makefile code and the observed behavior back this up. (I
expect that this is because there is less use of header files in
this area, because most unit tests are self-contained within a
single .c file.)
Something else is very wrong then.
Not really, it's just a less-cabable system than kbuild.
