- mark guest pages as accessed with the Linux lru (Izik Eidus)
- more portability work (Jerone Young, Xiantao Zhang)

Notes:
      If you use the modules bundled with kvm-54, you can use any version
of Linux from 2.6.9 upwards.
      If you use the modules bundled with Linux 2.6.20, you need to use
kvm-12.
      If you use the modules bundled with Linux 2.6.21, you need to use
kvm-17.
      Modules from Linux 2.6.22 and up will work with any kvm version from
kvm-22.  Some features may only be available in newer releases.
      For best performance, use Linux 2.6.23-rc2 or later as the host.
