[amd64, i386] The FreeBSD virtual memory subsystem now supports fully transparent use
+of superpages for application memory; application memory pages
+are dynamically promoted to or demoted from superpages without any modification to
+application code. This change offers the benefit of large page sizes such as improved
+virtual memory efficiency and reduced TLB (translation lookaside buffer) misses without
+downsides like application changes and virtual memory inflexibility. This is disabled by
default and can be enabled by setting a loader tunable vm.pmap.pg_ps_enabled
to 1.
