Put the reference to any struct page mapped/tracked by a gfn=>pfn cache upon inserting the pfn into its associated cache, as opposed to putting the reference only when the cache is done using the pfn. In other words, don't pin pages while they're in the cache. One of the major roles of the gfn=>pfn cache is to play nicely with invalidation events, i.e. it exists in large part so that KVM doesn't rely on pinning pages.
