Subject: [PATCH] lguest: map Switcher text whenever we allocate a new
 pagetable.

It's always to same, so no need to put in the PTE every time we're
about to run.  Keep a flag to track whether the pagetable has the
Switcher entries allocated, and when allocating always initialize the
Switcher text PTE.
