[PATCH 0/5 v4] x86: Adapt CPU topology detection for AMD Magny-Cours

[Andreas Herrmann <andreas.herrmann3@amd.com>]

Changes to previous patch set:
- fixed allnoconfig compile error and link error if CONFIG_PCI=n
- fixed hotplug issue: cpumask of siblings sharing same L3 were not
  properly updated
- properly allocate cpu_node_map

Current patch set contains 5 patches:
- patch 1 adapts common code to show cpu_node_id,
  cpu_node_siblings and cpu_node_siblings_list in
  /sys/devices/system/cpu/cpu*/topology
- patch 2 prepares arch/x86 to provide cpu_node information
- patch 3 sets up cpu_node information for AMD Magny-Cours CPU
- patch 4 fixes L3 cache information for Magny-Cours
- patch 5 fixes mcheck code for Magny-Cours

Note that scheduler adaptions are still under construction/test. Hope
to send first version as RFC by end of this week.

Patches are against tip/master.
Please apply.

Thanks,

Andreas
