Vitalii Demianets 34cb275283 UIO: Fix concurrency issue ... In a SMP case there was a race condition issue between uio_pdrv_genirq_irqcontrol() running on one CPU and irq handler on another CPU. Fix it by spin_locking shared resources access inside irq handler. Also: - Change disable_irq to disable_irq_nosync to avoid deadlock, because disable_irq waits for the completion of the irq handler; - Change atomic bit-manipulation routines to their non-atomic counterparts as we already are guarding the code by spinlock.
