Have you done a git pull of your kvm-unit-tests repo lately? The patch
that introduces mmu_disable was commit a few months ago or so. Other
than your repo just not having mmu_disable(), then I can't think of why
it compiles for me and not you. If you have done a recent git pull, then
maybe do a 'make distclean; ./configure; make'

Thanks,
