That's a bit weird. Xi, maybe in a follow-up some time later, could
you move the GCC-internal stdarg.h rather into linux/printk.h, since
that's where the problem is coming from? Imho, it might be better off
there, no?

There was some discussion a while ago on whether to make printk.h self
contained or to disallow including it directly. Joe Perches [CCed]
had patches for that.
