The QUEUED_LOCK_STAT option to report queued spinlocks statistics was previously allowed only on x86 architecture. Now queued spinlocks are used in multiple architectures, we now allow QUEUED_LOCK_STAT to be enabled for all those architectures that use queued spinlocks. This option is listed as part of the general architecture-dependent options.
