One part of the acpi_cpu patch I am going to commit rather soon. For the other part I am going to wait (and more actively push) for a review for some more time. Regarding the ref. count patch - given the probabilistic nature of the bug and my being not sure about the need for the change I am going to investigate / analyze the issue further before making any decision. That's my current plan. -- Andriy Gapon
