The kernel no longer uses an external unifdef -- it has its own in
scripts/unifdef.c. If you want to work with the upstream kernel to
change that to sunifdef, go ahead.

Can 'sunifdef -U__KERNEL__' fix up stuff like...

#if defined(__KERNEL__) && defined(__FOO__)
 and
#if defined(__KERNEL__) || defined(__BAR__)

... by treating them as '#if 0' (and eliding completely) and by
rewriting to just #ifdef __BAR__, respectively? If so, changing the
upstream kernel seems like it would be useful.
