On a freshly git pull'ed checkout with a 2.6.27 host kernel:

/dev/shm/x/kvm-userspace/kernel/x86/lapic.c: In function ‘apic_get_tmcct’:
/dev/shm/x/kvm-userspace/kernel/x86/lapic.c:570: error: implicit
declaration of function ‘hrtimer_expires_remaining’
/dev/shm/x/kvm-userspace/kernel/x86/lapic.c:570: error: incompatible
types in assignment

I'd say the problem is the

#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,27)

which should be 2.6.28, right?
