I don't know.  I was copying the style and #define used in x86_autoconf.c
for consitency.

cpu_rootconf() is called just before the root fs is mounted in
init_main.c:main().  So all the devices and other subsystems are already
on-line.

But do we want this code in the kernel all the time?  I guess no one has
used this in years.
