From 61e7751eca16b3bbc16168c631f6cbcd28206ab2 Mon Sep 17 00:00:00 2001
From: Miod Vallat <miod@cvs.openbsd.org>
Date: Sat, 5 Jan 2008 00:36:14 +0000
Subject: Mark vadvise(2) as obsolete and remove its implementation, so instead
 of returning EINVAL, you'll get ENOSYS. No serious code has used this system
 call in at least fifteen years.

The libc stub will be removed at the next major crank time.
