This change adds a per-p free page cache which the page allocator may allocate out of without a lock. The change also introduces a completely lockless page allocator fast path. Although the cache contains at most 64 pages (and usually less), the vast majority (85%+) of page allocations are exactly 1 page in size. Updates #35112.
