Alan Cox 3c76db4c64 Precisely document the synchronization rules for the page's dirty field.
(Saying that the lock on the object that the page belongs to must be held
only represents one aspect of the rules.)

Eliminate the use of the page queues lock for atomically performing read-
modify-write operations on the dirty field when the underlying architecture
supports atomic operations on char and short types.

Document the fact that 32KB pages aren't really supported.
