This patch adds a call to load_kvm_registers after creation of vcpu. This is required for ppc since we are required to set certain registers before boot. This should not have any effect on the curren x86 code (though I need to test this to make sure).

What I would like though are some comments on the fix. Is this the right place for this? We had this in our platform setup code, but with recent code changes it will not work there anymore).
