It looks to me that our pmap take alpha_pal_imb() wrong. Our pmap apparently assume that I-cache like TLB is virtually indexed and tagged with the ASN. So we call alpha_pal_imb() only when start new ASN generation. NetBSD have completely different idea (I-cache is indexed by the physical address?) and call alpha_pal_imb() in every second pmap function. I suspect they are right... Comments?
