* 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.
* pmap-gen.c Fix all functions to take or return PMAPS
instead of MAPS.
* alloc.c: Remove everything except kmalloc_node().
All runtime code now uses kmalloc() directly.
