No. Don't.

This pointless #ifdeffery in the vector header needs to vanish from the
KVM tree.

Why would you take the #ifdef mess into tasteful code just because
someone decided that #ifdeffing out constants in a header which is
maintained by other people is a brilliant idea?

The #ifdeffery in the idtentry header is unavoidable and the extra NULL
defines are at the right place and not making the actual code
unreadable.

Thanks,
