At least it would make the diffstat smaller to allow for rename
detection when the old file is deleted in the same patch:

MAINTAINERS | 1 +
{arch/x86/include/asm => include/linux/x86}/intel-family.h | 6 +++---
2 files changed, 4 insertions(+), 3 deletions(-)

...one thing people have done in the past is include a conversion
script in the changelog that produced the diff. That way if a
maintainer wants to be sure to catch any new usage of the header at
the old location they just run the script.

I am not aware of x86 maintainer preference here. Either way you decide
to go you can add:
