[ANNOUNCE] kvm-44 release

[Avi Kivity <avi-atKUWr5tajBWk0Htik3J/w@public.gmane.org>]

An important fix to guest smp (it boots now!), and a performance 
improvement on Intel hardware.  I get about 5% boost on a kernel build.

There's a new module parameter to kvm-intel.ko that can disable this 
mechanism, bypass_guest_pf.  Load the module with bypass_guest_pf=0 to 
disable the optimization.  It shouldn't be necessary to do that on 
current processors; it's mostly to protect kvm against changes in 
hardware since the patch uses reserved bits.

As usual, if you have an issue please try with -no-kvm-irqchip and report.

Changes from kvm-43:
- fix smp guest boot
- fix IDE emulation bug with newer guest kernels (S.Çağlar Onur)
- support VMware server as guest (Ryan Harper)
- fix smp race in shadow code (Izik Eidus)
- allow guest page faults to bypass kvm on Intel (performance boost)

Notes:
     If you use the modules bundled with kvm-44, 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.
