There are 2 ways of dealing with this:
1) Call the ENABLE_CAP on every vcpu. That way one CPU may handle
this hypercall in the kernel while another one may not. The same as we
handle PAPR today.
2) Create a new ENABLE_CAP for

I don't like bloat usually. But Alexey even had an #ifdef DEBUG in
there to selectively disable in-kernel handling of multi-TCE. Not
calling ENABLE_CAP would give him exactly that without ugly #ifdefs in
the kernel.
I don't see much

Debug code that requires code changes is prohibited, yes.
Debug code that is runtime switchable (pr_debug, trace points, etc)

So I must add one more ioctl to enable MULTITCE in kernel handling. Is it
what you are saying?
I can see KVM_CHECK_EXTENSION but I do not see KVM_ENABLE_EXTENSION or
anything like that.
KVM_ENABLE_CAP. It's how we enable sPAPR
