	* storage.c (shadow_setup): Support the case where the folio is
	full.
	(storage_alloc_): If AS_INIT_DONE is false, use as_alloc_slow to
	allocate an address.  Only call shadow_setup if CAP is not NULL.
	* as.h (as_alloc_slow): Remove parameter data_mappable and
	parameter may_alloc.  Return a struct hurd_object_desc *, not an
	addr_t.
	* as.c (as_alloc): Assert that AS_INIT_DONE is true.  Improve
	debugging output.
	(as_slot_ensure): Assert that AS_INIT_DONE is true.
	(as_alloc_slow): Remove parameter data_mappable and parameter
	may_alloc.  Return a struct hurd_object_desc *, not an addr_t.
	Don't special case page-sized objects, always find a void
	capability.  Don't return an address twice.  Don't use
	capability slots in folios.
	(as_init:add): Take additional argument, addr.  Use this rather
	than DESC->OBJECT.  Generalize code for iterating over folios and
	cappages.  Correctly walk folios.
	(as_init): Call add on both a descriptor object and its storage.
	(as_walk): Rewrite such that if AS_INIT_DONE is not true, we
	don't use a recursive function.  If the callback function returns -1,
	then don't descend.
	(as_walk:do_walk): Also walk folios.

viengoos/

2007-12-14  Neal H. Walfield  <neal@gnu.org>

	* viengoos.c (system_task_load:csalloc): Remove function.
	(system_task_load): Don't allocate additional capability slots for
	the objects we allocate, just use the address of the storage
	object.

ruth/

2007-12-14  Neal H. Walfield  <neal@gnu.org>

	* ruth.c (main): Only check the objects contained immediately
	within a folio for shadow objects.
