kvm.h has
#define KVM_SET_GUEST_DEBUG _IOW(KVMIO, 0x9b, struct kvm_guest_debug)
and
#define KVM_IA64_VCPU_SET_STACK _IOW(KVMIO, 0x9b, void *)
Seems that these could conflict?

Argh...
The IA64 world also collides with KVM_NMI - though I have no clue if
NMIs are known to that arch.
The good news is that different structure sizes (and different flags for
0x9a) should resolve the conflict numerically. Still messy, though.
