o Emit everything (ioconf.*, Makefile, ...) per-attribute.

o Generate modular(9) related information.  Especially module dependency.

o Rename "interface attribute" to "bus".

  Instead of

	define	audiobus {}
	attach	audio at audiobus

  Do like this

	defbus	audiobus {}
	attach	audio at audiobus

o Sort objects in more reasonable order.

  Put machdep.ko in the lowest address.  uvm.ko and kern.ko follow.

  Kill alphabetical sort (${OBJS:O} in sys/conf/Makefile.inc.kern.

  Use ldscript.  Do like this

	.text :
	AT (ADDR(.text) & 0x0fffffff)
	{
	  *(.text.machdep.locore.entry)
	  *(.text.machdep.locore)
	  *(.text.machdep)
	  *(.text)
	  *(.text.*)
	  :

  Kill linker definitions in sys/conf/Makefile.inc.kern.
