Tom efe2b75017 Kernel: Optimize single physical page allocation and randomize returns 
Rather than trying to find a contiguous set of bits of size 1, just
find one single available bit using a hint.

Also, try to randomize returned physical pages a bit by placing them
into a 256 entry queue rather than making them available immediately.
Then, once the queue is filled, pick a random one, make it available
again and use that slot for the latest page to be returned.
