Having 2 potential places for the same definition causes a small
ongoing maintenance / review burden, so I vote moving the file rather
than leaving a place holder, but it's ultimately an x86 maintainer
call.

I thought the patch kept the old file as a stub with just one line:

#include <linux/x86/intel-family.h>

to grab the real data from the new location.  So the information isn't
in two places.

$ git grep -l asm/intel-family.h | wc -l
53

Dang. We seem to love spraying model specific code all over the place :-(

My opinion is to post as Iwona wrote it ... but be prepared for the maintainers
to say "It's only 53 files ... just fix them all"
