I've reviewed and commented on all of these, asked a few questions, made a 
few changes, and queued the results for 2.6.39 in two branches of 
git://git.pwsan.com/linux-2.6:

clk_a_2.6.39 (for the autoidle-independent fixes)
clk_autoidle_a_2.6.39 (for the autoidle-specific code and data changes)

Both branches have been added to the 'integration-2.6.39' branch of 
git://git.pwsan.com/linux-integration, and are available as part of the 
tag "integration-2.6.39-20110212-004".


thanks,
