[RFC PATCH v2 0/2] powerpc: add support for new hcall H_BEST_ENERGY

[Vaidyanathan Srinivasan <svaidy@linux.vnet.ibm.com>]

Hi,

The following series adds a powerpc pseries platform module for
exporting platform energy management capabilities.

The module exports data from a new hypervisor call H_BEST_ENERGY.

Comments and suggestions made on the previous iteration of the patch
has been incorporated.

[RFC] powerpc: add support for new hcall H_BEST_ENERGY
http://lists.ozlabs.org/pipermail/linuxppc-dev/2010-March/080796.html

Changes from v1:

* Cleanup cpu/thread/core APIs
* Export APIs to module instead of threads_per_core
* Use of_find_node_by_path() instead of of_find_node_by_name()
* Error checking and whitespace cleanups

Please review and let me know your comments.  I will post the next
version ready for inclusion into powerpc/next tree along with test
reports.

The current patch series is on 2.6.34-rc6.

Thanks,
Vaidy
