[ANNOUNCE] kvm-45 release

[ANNOUNCE] kvm-45 release

[Avi Kivity]

Qemu-cvs as of yesterday has been merged into kvm.  Everything I tested 
still works, but undoubtedly a few rough edges remain.  The merge brings 
too many goodies to list; have fun exploring.

I've also thrown in a network latency improvement when using the tap 
device (bridged networking); on may machine this reduces guest->host 
ping round trip latency from 940 microseconds to 78 microseconds.

Less visible but also noteworthy is the removal of page->private use
for guest pages, an important step towards swapping guest pages.

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

Changes from kvm-44:
- don't use page->private for guest pages (Izik Eidus)
- x86 emulator cleanups, simplifications, and fixes (Laurent Vivier, 
Qing He)
- apic round robin delivery mode cleanup (Qing He)
- merge qemu-cvs
- fix compilation on older kernels (Rusty Russell, me)
- reduce tap networking latency
- fix FC6 x86_64 booting with -no-kvm
- fix code dump on exception

Notes:
     If you use the modules bundled with kvm-45, 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.
