Thanks Kevin, this series should bridge the gap nicely between the current 
code, and the point in time that we're able to move these functions into 
PRM/CM device driver code.  And allow us to avoid adding more cpu_is_*() 
when we merge Vaibhav's hwmod changes.

As you've probably seen, the patches have been updated here.  The function 
pointers have been made file-static rather than per-hwmod; this should 
conserve some memory and cache.  Since they don't change on a per-hwmod 
basis, this should be safe.  Also added quite a bit of kerneldoc -- 
basically I have an internal rule here now to ensure this exists on all 
functions and structures that are added, so it would be great to have this 
on future code :-)

The updated series is at git://git.pwsan.com/linux-2.6 in 
the "hwmod_soc_conditional_cleanup_3.5" branch.  Please let me know if 
you have any comments.  It's only compile-tested here so far.  I'll be 
rebasing my local copy of Vaibhav's series on it and will plan to send it 
upstream for 3.5.
