Catalin Marinas 08e875c16a arm64: SMP support ... This patch adds SMP initialisation and spinlocks implementation for AArch64. The spinlock support uses the new load-acquire/store-release instructions to avoid explicit barriers. The architecture also specifies that an event is automatically generated when clearing the exclusive monitor state to wake up processors in WFE, so there is no need for an explicit DSB/SEV instruction sequence. The SEVL instruction is used to set the exclusive monitor locally as there is no conditional WFE and a branch is more expensive. For the SMP booting protocol, see Documentation/arm64/booting.txt.
