Split kvm_arch_vcpu_create() into kvm_arch_vcpu_create() and kvm_arch_vcpu_setup(), enabling preemption notification between the two. This mean that we can now do vcpu_load() within kvm_arch_vcpu_setup(). Signed-off-by: NAvi Kivity <avi@qumranet.com>

KVM's nopage handler calls gfn_to_page() which acquires the mmap_sem when calling out to get_user_pages(). nopage handlers are already invoked with the mmap_sem held though. Introduce a __gfn_to_page() for use by the nopage handler which requires the lock to already be held. This was noticed by tglx.

This patch based on CR8/TPR patch, and enable the TPR shadow (FlexPriority) for 32bit Windows. Since TPR is accessed very frequently by 32bit Windows, especially SMP guest, with FlexPriority enabled, we saw significant performance gain.
