Hi,

	Please take a look at these changes to fix the problems reported by
Wang Nan wrt accesses to the cpu_topology_map information.

	The fixes are present on these following two csets:

  perf event: Use machine->env to find the cpu -> socket mapping
  perf report: Do not blindly use env->cpu[al.cpu].socket_id

	The rest are fixes made while working on this, infrastructure to enable
the fixes, reverts for things that ended up not being necessary and some
cleanups.

	It is available at:

 git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git perf/env

	Please let me know if I can have your Acked-by, Tested-by or
Reviewed-by.

- Arnaldo
