Will Deacon 0ea366f5e1 arm64: atomics: prefetch the destination word for write prior to stxr ... The cost of changing a cacheline from shared to exclusive state can be significant, especially when this is triggered by an exclusive store, since it may result in having to retry the transaction. This patch makes use of prfm to prefetch cachelines for write prior to ldxr/stxr loops when using the ll/sc atomic routines.
