+         Normally, and according to the Linux spec, anonymous memory obtained
+         from mmap() has it's contents cleared before it is passed to
+         userspace.  Enabling this config option allows you to request that
+         mmap() skip that if it is given an MAP_UNINITIALIZED flag, thus
+         providing a huge performance boost.  If this option is not enabled,
+         then the flag will be ignored.
+
+         This is taken advantage of by uClibc's malloc(), and also by
+         ELF-FDPIC binfmt's brk and stack allocator.
+
+         Because of the obvious security issues, this option should only be
+         enabled on embedded devices where you control what is run in
+         userspace.  Since that isn't generally a problem on no-MMU systems,
+         it is normally safe to say Y here.
