Does following patch meet your need?

     if(vpta.vf){
         pval = ia64_call_vsa(PAL_VPS_THASH, vadr, vrr.rrval,
                              vpta.val, 0, 0, 0, 0);
+  this is a work-around, this check will be removed.
+               if(pval-(vpta.val&~0x7fff) >= (1UL << vpta.size)){
+               pval = (vpta.val & ~0x7FFF) | (pval & ((1UL <<
vpta.size) - 1));
+               }
     }else{
