- atomically set accessed and dirty bit on guest ptes (Marcelo Tosatti)
- use ->fault() vma op instead of ->nopage()
- remove abi 10 libkvm compatibility

Notes:
If you use the modules bundled with kvm-56, 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.
