This is documentation for an existing ioctl, no?
And yes, a reserved area would've been nice ;). But it's too late for that one now.

Indeed. We'll have to keep this for backward compatibility and introduce
a new mechanism for larger interrupt structures.

Newer kernels (linux-next with the transparent huge page patches)
use rrbm if the feature is announced via feature bit 66.
RRBM will cause intercepts, so KVM does not handle it right now,
causing an illegal instruction in the guest.
The easy solution is to disable the feature bit for the guest.
This fixes bugs like:
