Merge tag 'generic-ticket-spinlocks-v6' into for-next
asm-generic: New generic ticket-based spinlock This contains a new ticket-based spinlock that uses only generic atomics and doesn't require as much from the memory system as qspinlock does in order to be fair. It also includes a bit of documentation about the qspinlock and qrwlock fairness requirements. This will soon be used by a handful of architectures that don't meet the qspinlock requirements. * tag 'generic-ticket-spinlocks-v6': csky: Move to generic ticket-spinlock RISC-V: Move to queued RW locks RISC-V: Move to generic spinlocks openrisc: Move to ticket-spinlock asm-generic: qrwlock: Document the spinlock fairness requirements asm-generic: qspinlock: Indicate the use of mixed-size atomics asm-generic: ticket-lock: New generic ticket-based spinlock
