[PATCH] Use kvm_on_each_cpu in preempt.c

[PATCH] Use kvm_on_each_cpu in preempt.c

[Alexander Graf]

Compat modules need to use kvm_on_each_cpu instead on on_each_cpu
in order to be compatible throughout various kernel versions.

Unfortunately preempt.c uses on_each_cpu. This patch changes preempt.c
to also use the kvm version, so it is compatible with the rest of the
external module build.

This fixes building on newer kernels without preempt notifiers.
