Those EXPORT_SYMBOL(sym) in lib/ctype.c|cmdline.c caused this build failure. I added below code to skip linux/export.h including, it works. However I haven't found out why EXPORT_SYMBOL in boot stage caused the failure. #define _LINUX_EXPORT_H #define EXPORT_SYMBOL(sym) > > and build the kernel the regular way. > > Thanks, > > Ingo
