I've seen the same error when trying to work around vprintk issue on
i386 with CONFIG_EXPERT=y CONFIG_EARLY_PRINTK=n

instead of fixing 'printk.c' I've changed 'include/linux/printk.h:95'
-void early_vprintk(const char *fmt, va_list args);
+asmlinkage void early_vprintk(const char *fmt, va_list args);

and compiled with CONFIG_EARLY_PRINTK=y. Not sure if that is an option
on ARM.

Herman has reported the latter issue earlier today.

ciao,
robin
