[PATCH 7/8] numa: in-kernel profiling: use cpu_to_mem() for per cpu allocations

[Lee Schermerhorn <lee.schermerhorn@hp.com>]

Against:  2.6.34-rc3-mmotm-100405-1609

Patch:  in-kernel profiling -- support memoryless nodes.

In kernel profiling requires that we be able to allocate "local"
memory for each cpu.  Use "cpu_to_mem()" instead of "cpu_to_node()"
to support memoryless nodes.

Depends on the "numa_mem_id()" patch.
