Now all arch/ia64/lib/ lib-y objects with exports in them get pulled from their library by that sucker, and some of them require symbols *not* in bootloader. AFAICS, solved by moving several objects in arch/ia64/lib/ from obj-* to lib-* and dropping built-in.o from ld arguments when building bootloader. Hopefully fixed variant pushed... -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
