It seems as though I need to insert vtd.o instead of vtd.c
My Kbuild file now looks like this:
# trick to get the kvm-specific CONFIG_KVM_* definitions,
# because the kernel source tree won't have them
include $(obj)/../config.kbuild
obj-m := kvm.o kvm-intel.o kvm-amd.o
kvm-objs := vtd.o kvm_main.o x86.o mmu.o x86_emulate.o ../anon_inodes.o irq.o
i8 259.o \
lapic.o ioapic.o preempt.o i8254.o coalesced_mmio.o \
../external-module-compat.o
ifeq ($(EXT_CONFIG_KVM_TRACE),y)
kvm-objs += kvm_trace.o
endif
kvm-intel-objs := vmx.o vmx-debug.o ../external-module-compat.o
kvm-amd-objs := svm.o ../external-module-compat.o
CFLAGS_kvm_main.o = -DKVM_MAIN
The modules do compile with this option specified.
Unfortunately, the error inserting the modules still persists.
Any other ideas?

Add vtd.c to kvm-userspace/kernel/x86/Kbuild kvm-objs item should get it done.
