IOW, you want the patch below?
Not that I'm a big fan of this approach, but if it should be done this
way, it should be done right.

Let IA64_GENERIC select more stuff (as wanted by the ia64 developers).

This selects the system type of your hardware. A "generic" kernel
will run on any supported IA-64 system. However, if you configure
a kernel for your specific system, it will be faster and smaller.
