+         This enables emulation of the legacy vsyscall page.  Disabling
+         it is roughly equivalent to booting with vsyscall=none, except
+         that it will also disable the helpful warning if a program
+         tries to use a vsyscall.  With this option set to N, offending
+         programs will just segfault, citing addresses of the form
+         0xffffffffff600?00.
+
+         This option is required by many programs built before 2013, and
+         care should be used even with newer programs if set to N.
+
+         Disabling this option saves about 7K of kernel size and
+         possibly 4K of additional runtime pagetable memory.
