2015-08-26pm80xx: Add PORT RECOVERY TIMEOUT supportViswas G2-17/+68
PORT RECOVERY TIMEOUT is the maximum time between the controller's detection of the PHY down until the receipt of the ID_Frame (from the same remote SAS port). If the time expires before the ID_FRAME is received, the port is considered INVALID and can be removed. The IOP_EVENT_PORT_RECOVERY_TIMER_TMO event is reported following the IOP_EVENT_ PHY_DOWN event when the PHY/port does not recover after Port Recovery Time.

2014-11-27libsas: remove task_collector modeChristoph Hellwig3-21/+6
The task_collector mode (or "latency_injector", (C) Dan Willians) is an optional I/O path in libsas that queues up scsi commands instead of directly sending it to the hardware. It generall increases latencies to in the optiomal case slightly reduce mmio traffic to the hardware. Only the obsolete aic94xx driver and the mvsas driver allowed to use it without recompiling the kernel, and most drivers didn't support it at all. Remove the giant blob of code to allow better optimizations for scsi-mq in the future.

All drivers use the implementation for ramping the queue up and down, so instead of overloading the change_queue_depth method call the implementation diretly if the driver opts into it by setting the track_queue_depth flag in the host template. Note that a few drivers validated the new queue depth in their change_queue_depth method, but as we never go over the queue depth set during slave_configure or the sysfs file this isn't nessecary and can safely be removed.

For calling task_done there is no need to enable the irq. So instead of using spin_lock_irqsave and spin_unlock_irqrestore, spin_lock and spin_unlock is used now.
