The new rules introduced here are: 0) For all %.so compiling: QEMU_CFLAGS += -fPIC 1) %.o in $(common-obj-m) is compiled to %.o, then linked to %.so. 2) %.mo in $(common-obj-m) is the placeholder for %.so for pattern matching in Makefile. It's linked to "-shared" with all its dependencies (multiple *.o) as input. Which means the list of depended objects must be ruled out in each sub-Makefile.objs with an variable: foo.mo-objs := bar.o baz.o qux.o in the same style with foo.o-cflags and foo.o-libs.
