Sean Christopherson 59320074af KVM: Register /dev/kvm as the _very_ last thing during initialization 
commit 2b01281273738bf2d6551da48d65db2df3f28998 upstream.

Register /dev/kvm, i.e. expose KVM to userspace, only after all other
setup has completed.  Once /dev/kvm is exposed, userspace can start
invoking KVM ioctls, creating VMs, etc...  If userspace creates a VM
before KVM is done with its configuration, bad things may happen, e.g.
KVM will fail to properly migrate vCPU state if a VM is created before
KVM has registered preemption notifiers.
