+Page Table Entry
+----------------

+::
+ %ppte
+
+Print standard page table entry pte_t.
+
+Passed by reference.
Curious, why the decision to pass by reference?
Just to make this via %p<> based address mechanism. But wondering
will it be better for the pte to be represented via value instead
of reference ?
We commonly pass ptes to functions through value, not reference, that's
why I am asking.
