SVN rev 189610 on 2009-03-10 02:12:03Z by alc
Eliminate the last use of the recursive mapping to access user-space page
table pages. Now, all accesses to user-space page table pages are
performed through the direct map. (The recursive mapping is only used
to access kernel-space page table pages.)
Eliminate the TLB invalidation on the recursive mapping when a user-space
page table page is removed from the page table and when a user-space
superpage is demoted.
