SRU Justification:
Impact: Various Qemu/KVM guests hang while attempting to reboot due to a missing kvm clock kernel patch.
Testcase: Some guests are more susceptible to this issue. A 32-bit RHEL-5 (or compatible) 2-CPU VM guest hangs 100% of the time (fully reproducible.) I have personally seen Ubuntu VM guests hang too but this is much harder to reproduce.
Fix: A one line patch from 2.6.39
