History
Alan Cox cd914c2fc2 Prepare for adding psind == 1 support to armv6's pmap_enter(). 
Precompute the new PTE before entering the critical section.

Eliminate duplication of the pmap and pv list unlock operations in
pmap_enter() by implementing a single return path.  Otherwise, the
duplication will only increase with the upcoming support for psind == 1.
