Steven Rostedt (Google) b0407f68d9 ring-buffer: Do not record in NMI if the arch does not support cmpxchg in NMI ... [ Upstream commit 712292308af2265cd9b126aedfa987f10f452a33 ] As the ring buffer recording requires cmpxchg() to work, if the architecture does not support cmpxchg in NMI, then do not do any recording within an NMI.
