PR1923
* 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.
* 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.

* alloc.c (__stp_valloc_percpu): Use same code for up and smp.
(_stp_per_cpu_ptr): New macro.
* user/alloc.c: Ditto.
* map.c: Use _stp_map_cpu_ptr().
* map-stat.c: Ditto.
* pmap-gen.c: Ditto.
* runtime.h: Include alloc.c
* user/runtime.h: Ditto.

* pmap-gen.c (_stp_pmap_get()): New function. Aggregates
the per-cpu map nodes into an aggregation map node.
* map.c (_stp_new_agg): Return a struct map_node *.
(_stp_add_agg): If count is 0 when adding,
just set the stats.

* map.c: Doc updates.
* pmap-gen.c: Change a bunch of generated function names to
avoid conflicts with maps with the same key and value types.

* map.h: Remove HSTAT_LOG and HSTAT_LINEAR.
* map-gen.c: Fix comment.
* pmap-gen.c: Ditto.

* map.c (_stp_map_init): New function. Extracted from _stp_map_new()
so it can be used in _stp_pmap_new().
(_stp_map_new): Call _stp_map_init().
(_stp_pmap_new): New function.
(_stp_pmap_new_hstat_linear): New function.
(_stp_pmap_new_hstat_log): New function.
(_stp_pmap_del): New function.
(_stp_pmap_printn_cpu): New function.
(_stp_pmap_printn): New function.
(_stp_new_agg): New function.
(_stp_add_agg): New function.
(_stp_pmap_agg): New function.
(_new_map_clear_node): New function.
* map.h (struct map_root): Add Hist struct. Add copy
and cmp function pointers for pmaps.
* stat.h: Remove Stat struct. Replace with Hist struct
that is limited to only histogram params.
* map-stat.c: Fix up references to histogram params in map_root.
* stat-common.c: Ditto.
* stat.c: Ditto.
* pmap-gen.c: New file. Implements per-cpu maps.
* map-gen.c: Minor bug fixes. Use new VAL_IS_ZERO() macro.
* alloc.c (vmalloc_node): For NUMA, provide a vmalloc that
does node-local allocations.
(_stp_alloc_cpu): A version of _stp_alloc() that does
node-local allocations.
(_stp_valloc): A version of _stp_valloc() that does
node-local allocations.
(__stp_valloc_percpu): New function. Like alloc_percpu()
except uses _stp_valloc().
