2015-02-02hpsa: do not queue commands internally in driverDon Brace
By not doing maintaining a list of queued commands, we can eliminate some spin locking in the main i/o path and gain significant improvement in IOPS. Remove the queuing code and the code that calls it; remove now-unused interrupt code; remove DIRECT_LOOKUP_BIT. Now that the passthru commands share the same command pool as the main i/o path, and the total size of the pool is less than or equal to the number of commands that will fit in the hardware fifo, there is no need to check to see if we are exceeding the hardware fifo's depth.

We have commands reserved for internal use. This is laying the groundwork for removing the internal queue of commands from the driver so that the locks that protect that queue may be removed.

2015-02-02hpsa: reserve some commands for use by driverStephen Cameron
We need to reserve some commands for device rescans, aborts, and the pass through ioctls, etc. so we cannot give them all to the scsi mid layer. This is in preparation for removing cmd_special_alloc and cmd_special_free so that we can stop queuing commands internally in the driver so that we can remove the locks thta protect the queue that we will no longer have.

2015-02-02hpsa: avoid unneccesary calls to resource freeing functionsRobert Elliott
If hpsa_allocate_cmd_pool failed, we were calling two functions unnecessarily: hpsa_free_sg_chain_blocks(h); hpsa_free_cmd_pool(h); This didn't cause any problem, as those functions can tolerate being called when what they free hasn't been allocated (relevant pointers would be NULL) but it is potentially confusing.

2015-02-02hpsa: notice all request_irq errorsRobert Elliott
In MSI and MSI-X mode, where hpsa asks for more than one interrupt, hpsa_request_irqs forgets if the first request_irq call failed if later ones succeed. It needs to exit the loop on any failure rather than continue, freeing all irqs that were requested until that point. Also, it needs to clear out the q numbers up to MAX_REPLY_QUEUES. The same is true for the general hpsa_free_irqs function. Tested with error injection of -ENOSYS on the 4th call: [ 9.277691] injecting error in inj_request_irq: 1 4 [ 9.277780] hpsa 0000:02:00.0: failed to get irq 35 for hpsa1 [ 10.711623] scsi host1: Error handler scsi_eh_1 exiting [ 10.739170] hpsa: probe of 0000:02:00.0 failed with error -38 Reviewed-by: Scott Teel <scott.teel@pmcs.com> Signed-off-by: Robert Elliott <elliott@hp.com> Signed-off-by: Don Brace <don.brace@pmcs.com> Signed-off-by: Christoph Hellwig <hch@lst.de>

Sometimes when the card is restarted it may cause - "irq 16: nobody cared (try booting with the "irqpoll" option)" that is likely caused so, that the card, after the hard reset finishes, pulls on the irq. Disabling the ints before or after the hpsa_kdump_hard_reset_controller fixes it. At this point we can't know in which state the card is, so using SA5_INTR_OFF + SA5_REPLY_INTR_MASK_OFFSET defines directly, instead of the function the drivers provides, seems to be apropriate.

2015-02-02[media] adv7180: Add support for the adv7280/adv7281/adv7282Lars-Peter Clausen
This patch adds support for the adv7280/adv7281/adv7282 devices to the adv7180 driver. They are very similar to the adv7182, the main difference from the drivers point of view are some different tuning constants for improved video performance.
