These patches fix some bugs found in -tip testing: 1. Avoid a build error for some compiler arguments for out-of-tree modules. 2. Add a generic atomic_or(). 3. Use atomic_or() to avoid a lockdep splat. Following this will be specific atomic_or() implementations for a couple of architectures. Thanx, Paul ------------------------------------------------------------------------ include/linux/atomic.h | 13 +++++++++++++ include/linux/rcupdate.h | 5 +++-- kernel/rcutree.c | 13 +++++-------- kernel/rcutree.h | 4 +++- 4 files changed, 24 insertions(+), 11 deletions(-)
