Catalin Marinas 4ecf7ccb19 arm64: spinlock: retry trylock operation if strex fails on free lock ... An exclusive store instruction may fail for reasons other than lock contention (e.g. a cache eviction during the critical section) so, in line with other architectures using similar exclusive instructions (alpha, mips, powerpc), retry the trylock operation if the lock appears to be free but the strex reported failure.
