[ANNOUNCE] kvm-86 release

[Avi Kivity <avi@redhat.com>]

Many fixes, performance improvements, a preview of irqfd, but all of 
these pale in comparison to

Notes:
     If you use the modules bundled with kvm-87, you can use any version
of Linux from 2.6.16 upwards.  You may also use kvm-87 userspace with
the kvm modules provided by Linux 2.6.25 or above.  Some features may
only be available in newer releases.

I have a truly marvellous patch that fixes the bug which this
signature is too narrow to contain.
