Thereby adding a nice dollop of bloat to everyone's kernel.  I don't
think that is justifiable given that the audience for this feature is
about eight people :(

How's about CONFIG_UNMAPPED_PAGECACHE_CONTROL?

Also this patch instantiates sysctl_min_unmapped_ratio and
sysctl_min_slab_ratio on non-NUMA builds but fails to make those
tunables actually tunable in procfs.  Changes to sysctl.c are
needed.
