They're indeed unused so patch queued for 2.6.18.  I was planning to
eventually use the values deleted by your patch but came to the
conclusion they should rather be probed.  Another cleanup would be to
remove the per-processor definition of TO_PHYS_MASK - the fixed value
of 0x7ffffffffffffffULL should work for all processors.

Thanks,
