Work around paging bug. Somehow we seem to be ending up with entries in
the TLB which don't correspond to ptes with PG_V set; prior to this commit
I'm sometimes getting the wrong data when pages are loaded into the buffer
cache (they're being loaded, but the missing TLB invalidation is causing
the wrong data to be visible).
