2014-10-03[SCSI] uas: disable use of blk-mq I/O pathChristoph Hellwig
The uas driver uses the block layer tag for USB3 stream IDs. With blk-mq we can get larger tag numbers that the queue depth, which breaks this assumption. A fix is under way for 3.18, but sits on top of large changes so can't easily be backported. Set the disable_blk_mq path so that a uas device can't easily crash the system when using blk-mq for SCSI.

This reverts commit a86713b1536c818972675e6dd8c6e738f0379f1d. Kevin Hilman writes: Multiple boot failures on ARM[1] were bisected down to this patch. How was this patch tested, and on which platforms? Also, the changelog states that this should be done only for UART_CAP_SLEEP, but the patch does it for every UART. Greg, I suggest this patch be dropped from tty-next until it has been better described and tested.

2014-10-02ath9k: Fix flushing in MCC modeSujith Manoharan
When we are attempting to switch to a new channel context, the TX queues are flushed, but the mac80211 queues are not stopped and traffic can still come down to the driver. This patch fixes it by stopping the queues assigned to the current context/vif before trying to flush. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-10-02ath9k: Fix queue handling for channel contextsSujith Manoharan
When a full chip reset is done, all the queues across all VIFs are stopped, but if MCC is enabled, only the queues of the current context is awakened, when we complete the reset. This results in unfairness for the inactive context. Since frames are queued internally in the driver if there is a context mismatch, we can awaken all the queues when coming out of a reset. The VIF-specific queues are still used in flow control, to ensure fairness when traffic is high. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.
