	* map.h (struct map_root): Remove membuf.
	(struct pmap): Define.
	(PMAP): Declare.

	* map.c (_stp_map_init): Use kmalloc() to allocate individual
	nodes instead of using vmalloc() to allocate one big chunk.
	(_stp_map_new): Use kmalloc.
	(_stp_pmap_new): Use kmalloc. Return a PMAP.
	(__stp_map_del): New function. Free all the nodes in a map.
	(_stp_map_del): Call __stp_map_del() then free map struct.
	(_stp_pmap_del): Takes a PMAP. Calls __stp_map_del() for
	each cpu.
	(_stp_pmap_printn_cpu): Change arg to PMAP.
	(_stp_pmap_agg): Change arg to PMAP.
	(_stp_pmap_get_agg): Change arg to PMAP.

	* map-stat.c (_stp_pmap_new_hstat_linear): Use PMAP
	instead of MAP. Fix allocations.
	(_stp_pmap_new_hstat_log): Ditto.

	All runtime code now uses kmalloc() directly.
