And that's bad. Jeez, seriously. Don't argue this case. We enable new
features individually unless we're 100% sure we can keep everything
working. In this case an ENABLE_CAP doesn't hurt at all, because user
space still needs to handle the hypercalls if it wants them anyways.
But you get debugging for free for example.

An ENABLE_CAP is utterly pointless. More bloat. But you seem to like
it :-)

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.
