analyze_instr() is used in arch/powerpc/kvm/emulate_loadstore.c which 
can be a module as far as I can see in Makefile:

common-objs-y += powerpc.o emulate_loadstore.o

kvm-book3s_64-module-objs := \
	$(common-objs-y) \
	book3s.o \
	book3s_rtas.o \
	$(kvm-book3s_64-objs-y)

kvm-objs-$(CONFIG_KVM_BOOK3S_64) := $(kvm-book3s_64-module-objs)

config KVM_BOOK3S_64
	tristate "KVM support for PowerPC book3s_64 processors"
