Update the LinuxKPI: - Add more functions and types. - Implement ACCESS_ONCE(), WRITE_ONCE() and READ_ONCE(). - Implement sleepable RCU mechanism using shared exclusive locks. - Minor workqueue cleanup: - Make some functions global instead of inline to ease debugging. - Fix some minor style issues. - In the zero delay case in queue_delayed_work() use the return value from taskqueue_enqueue() instead of reading "ta_pending" unlocked and also ensure the callout is stopped before proceeding. - Implement drain_workqueue() function. - Reduce memory consumption when allocating kobject strings in the LinuxKPI. Compute string length before allocating memory instead of using fixed size allocations. Make kobject_set_name_vargs() global instead of inline to save some bytes when compiling.
