Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: Revert "net: Make accesses to ->br_port safe for sparse RCU" mce: convert to rcu_dereference_index_check() net: Make accesses to ->br_port safe for sparse RCU vfs: add fs.h to define struct file lockdep: Add an in_workqueue_context() lockdep-based test function rcu: add __rcu API for later sparse checking rcu: add an rcu_dereference_index_check() tree/tiny rcu: Add debug RCU head objects mm: remove all rcu head initializations fs: remove all rcu head initializations, except on_stack initializations powerpc: remove all rcu head initializations
