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?
