kvm-47 release

Today's news includes partial support for swapping. You can now run guests with more memory than you have on the host, and Linux will page them out to the swap file. The support is partial in that the guest will still pin a substantial amount of memory.

Changes from kvm-46:
- Reset fixes (Eddie Dong, me)
- Portability work (Carsten Otte)
- Cleanups (Anthony Liguori, Laurent Vivier)
- Simplify guest pagetable dirty bit management
- Fix nx bit for huge pages
- Fix write access to clean large pages (fixes rmap leak)
- Support for Linux 2.6.16 guests (movnti instruction) (Sheng Yang)
- Simplify apic timer backlog processing
- Move interrupt injection out of critical section
- x86 emulator work (Nitin A Kamble)
- restore freebsd support on AMD (fix smsw and lmsw) (Aurelien Jarno)
- Simplify guest page table walker
- Partial guest swapping (Izik Eidus)
- kvmctl improvements (Anthony Liguori)
- libkvm, qemu compilation against older kernels
- guest time accounting (Laurent Vivier)
- configure improvements (Carlo Marcelo Arenas Belon)
- fix 4GB+ configurations (Izik Eidus)
- cross compilation support (Jerone Young)

Notes:
If you use the modules bundled with kvm-47, 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.

Good day. First thanks for release 47. This is to report a problem with kvm-47 where my host locked up upon shutdown of windows 32 bit xp guest. Guest was running for about 15 min before shutdown. Host locked up when guest was at "you may now turn off your machine" screen.
