. common/include/arch/i386 is not actually an imported sys/arch/i386/include but leftover Minix files; remove and move to include/ . move include/ufs to sys/ufs, where it came from, now that we have a sys/ hierarchy . move mdocml/ to external/bsd/, now we have that . single sys/arch/i386/stand/ import for boot stuff
