Has it been applied to anything? I don't think so.
Is it still needed?
Not in qemu.git yet, still applicable AFAICT. CC'ing Paolo.

Should this lock be taken in process_l2meta? It's a bit easier to follow.

Can anybody else take the lock as reader again at this point? If not, I
wonder if this is more clear if you write it as a CoQueue.

For proper cmov insns, as well as the non-goto-tb case
of conditional branch.

Looking at http://lkml.indiana.edu/hypermail/linux/kernel/1205.0/00100.html
The new value for EAX is 0x4001.
This depends on
http://lists.gnu.org/archive/html/qemu-devel/2012-09/msg02497.html
As far as I known it is #5. It depends on (1), (2), (3) and (4).
Based on cpu-queue[1] branch.
From http://lkml.indiana.edu/hypermail/linux/kernel/1205.0/00100.html
EAX should be KVM_CPUID_FEATURES (0x4001) not 0.

EAX should be KVM_CPUID_FEATURES (0x4001) not 0.
If kvm is not configured, the additional option of hypervisor-level=1
(or hypervisor-level=0x4001) needs to be specified to get this.
