Pratt <anarchy@gentoo.org> - -COMPAT_VDSO is inappropriate for any modern Hardened Gentoo system.

Unfortunately, the -reason for the disappearance of these PaX configuration options is -often far from obvious to inexperienced users. - -Therefore, we disable the COMPAT_VDSO menu entry entirely. However, -COMPAT_VDSO operation can still be enabled via bootparam and sysctl -interfaces. Consequently, we must also disable the ability to select -COMPAT_VDSO operation at boot or runtime.
