Hello! This series features updates to allow sparse to do a better job of statically analyzing RCU usage: 1. Apply ACCESS_ONCE() to rcu_assign_pointer()'s target to prevent comiler mischief. Also require that the source pointer be from the kernel address space. Sometimes it can be from the RCU address space, which necessitates the remaining patches in this series. Which, it must be admitted, apply to a very small fraction of the rcu_assign_pointer() invocations in the kernel. This commit courtesy of Josh Triplett. 2-13. Apply rcu_access_pointer() to avoid a number of false positives. Changes from v1: o Fix grammar nit in commit logs.
