When you build with egcs printk becomes

__attribute__((regparm(0))) int printk(const char *, ...)

That is needed because a user might turn on register parameter passing too
and that would break when called from assembler unless marked with
regparm.

So if anything the "__attribute__((regparm(0)))" stuff needs to be taught
to genksyms.
