We do not provide compat for kvm groveling apps, they have to be recompiled.

Apps should avoid that as hard as they can and use sysctl based interfaces
instead.

I compiled the reported apps from source using pkgsrc current, pkgsrc 2016Q3 and also older versions of pkgsrc.
By the way libgtop and xosview are standard apps and nobody can change them as this, they are too complex.
But they are working OK in versions prior to NetBSD 7 !!
By example they work ok in NetBSD 6.1, 6.0, 5.2, 5.1, 5.0, 4.x

On the contrary, this is exactly the kind of situation that the
patches in pkgsrc are for.

If they are using /dev/kmem (or equivalently, libkvm) that is purely
an accident.

However, if so they ought to work when recompiled for NetBSD 7.x, so
probably something else is going on.
