Comment 2 Radim Krčmář 2014-01-21 19:21:06 UTC 
This is introduced by commit
  e66d2ae KVM: x86: Fix APIC map calculation after re-enabling
and fixed in
 0dce7cd kvm: x86: fix apic_base enable check
the next stable is going to have it. (I'll verify and close it then)
Comment 3 Radim Krčmář 2014-02-11 10:23:37 UTC 
Linux 3.12.10 has the fix. (kernel-3.12.10-300.fc20 and kernel-3.12.10-200.fc19)
Comment 4 Dr. David Alan Gilbert 2014-10-24 09:43:24 UTC 
I can see some mentions of this upstream as well:
