Yeah, Paolo's pointed out (and had some patches for) ARM's rather complicated cpu_get_tb_cpu_state(). My issue with his suggested fixes was that they were pretty fragile in terms of not having any guarantee that the change always produced the right tb cpu state flags answer... (I'm processing the pullreq, this just seemed like an interesting digression.) thanks -- PMM
