make menuconfigのCONFIG_COMPAT_VDSOはどこにありますか？

XenServer 5.6 fp1で軽量および半仮想化を実行するためにLinuxカーネルをコンパイルしようとしています。

ここで提供されているガイドを使用しています。http://www.mad-hacking.net/documentation/linux/deployment/xen/pv-guest-basics.xml

しかし、このオプションを選択したとき、私はパニックになりましたCONFIG_COMPAT_VDSO。

どこmake menuconfig？ウェブサイトにはオプションがあると記載されています。プロセッサのタイプと機能グループですが、次の項目は表示されません。
