This patch implements the inactive_clean list spoken of during the VM summit.
The LRU tail pages will be unmapped and ready to free, but not freeed.
This gives reclaim an extra chance.
This patch makes it possible to implement Martin Schwidefsky's
hypervisor-based fast page reclaiming for architectures without
millicode - ie. Xen, UML and all other non-s390 architectures.
That could be a big help in heavily loaded virtualized environments.
The fact that it helps prevent the iSCSI memory deadlock is a
huge bonus too, of course :)
