 You are right.  I should have read your example more carefully.
 
 Your patch can be improved by fixing the KERNEL case too and renaming
 __va_promote - there is no way to determine the promoted sizes without a
 builtin, and the args may have additional padding anyway, so __va_promote
 is a confusing name.  The corresponding macro is named __va_rounded_size
 in gcc/ginclude/stdarg.h and __va_size in NetBSD.
