These files would better have an .S extension as they
contain preprocessor macros.  From gcc.info:

:  For any given input file, the file name suffix determines what kind of
: compilation is done:
[...]
: 
: `FILE.s'
:      Assembler code.
: 
: `FILE.S'
:      Assembler code which must be preprocessed.

Our standard make(1) rules know about this:

: $ touch a.s; make -n a.o; rm a.s
: as  -o a.o a.s
: $ touch a.S ; make -n a.o ; rm a.S
: cc -O2 -fno-strict-aliasing -pipe  -c a.S

This doesn't matter much for the kernel build (it provides
its own rules to build from .[Ss]), but makes a difference
for a module build, if the latter needs to compile some of
the assembly.
