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 point in disabling it... but ok, if that's a valuable
feature, then shoot some VM level ENABLE_CAP (please don't iterate all
VCPUs, that's gross).

No use for me whatsoever as I only want to disable real more handlers and
keep virtual mode handlers enabled (sometime, for debug only) and this
capability is not about that - I can easily just not enable it in QEMU with
the exactly the same effect.

So please, fellas, decide whether I should iterate vcpu's or add ENABLE_CAP
per KVM. Thanks.
