History
Mark Johnston 5cff1f4dc3 Introduce vm_page_astate. 
This is a 32-bit structure embedded in each vm_page, consisting mostly
of page queue state.  The use of a structure makes it easy to store a
snapshot of a page's queue state in a stack variable and use cmpset
loops to update that state without requiring the page lock.

This change merely adds the structure and updates references to atomic
state fields.  No functional change intended.
