This doesn't quite parse correctly to me. Let's say it this way: Some old crusty CPUs need an extra delay that slows down booting. See the comment above 'init_udelay' for details. Newer CPUs don't need the delay. Right now, for Intel, Family 6 and only Family 6 skips the delay. That leaves out both the Family 15 (Pentium 4s) and brand new Family 18/19 models. The omission of Family 15 (Pentium 4s) seems like an oversight and 18/19 do not need the delay. Skip the delay on all Intel processors Family 6 and beyond. Is there anything wrong there?
