Nice, but this breaks the build:

  CC      init/main.o
In file included from include/linux/kobject.h:24:0,
                 from include/linux/module.h:16,
                 from init/main.c:13:
include/linux/kref.h: In function ‘kref_put’:
include/linux/kref.h:62:2: error: ‘kfree’ undeclared (first use in this function)
include/linux/kref.h:62:2: note: each undeclared identifier is reported only once for each function it appears in
include/linux/kref.h: In function ‘kref_sub’:
include/linux/kref.h:91:2: error: ‘kfree’ undeclared (first use in this function)
make[1]: *** [init/main.o] Error 1
make: *** [init] Error 2

Sorry, I can't apply this.

This was on an x86-64 build, my "stock" desktop system, nothing "odd" in the
config at all...
