I think at current state, it's way too early to extract out the common
code into macros, because for long format vhpt, the low level handler is
not even optimal.  And in the final form, it may not be the same as the
short format vhpt (OK, the linux page table walk will be the same, but
other part maybe not).

I would like to experiment with a few algorithms for lvhpt and best thing
to do in my opinion is to have parallel ivt.S (or ivt table to be precise).
