Hi Thomas,
In my opinion, having kvmclock page in __initdata for boot cpu, and setup it in init_hypervisor_platform(). Later, switch to memblock allocated memory in x86_init.hyper.guest_late_init() for all CPUs would not be too bad, and might be even use fewer lines of code. In addition, it won't have any overhead when kvm is not used.
