KVM-65 Released, Supports S390 Architecture

KVM-65 was released today. The most interesting feature in this release is support for the S/390 architecture, more specifically, the System z9 line of mainframes. On x86, the most interesting change is the separation of timer and I/O completion handling into a separate thread (these used to be serviced bythe same thread that executed vcpu 0). The change should result in improved responsiveness and better smp performance.
