2017-12-07ath10k: use 64-bit crash dump timestampsArnd Bergmann
The dump format uses 64-bit timestamps already, but calling getnstimeofday() only returns a 32-bit number on 32-bit architectures, so that will overflow in y2038. This changes it to use ktime_get_real_ts64() instead. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2017-12-07wlcore: use boottime for fw time syncArnd Bergmann
Using getnstimeofday()/timespec_to_ns() causes an overflow on 32-bit architectures in 2038, and may suffer from time jumps due to settimeofday() or leap seconds. I don't see a reason why this needs to be UTC, so either monotonic or boot time would be better here. Assuming that the fw time keeps running during suspend, boottime is better than monotonic, and ktime_get_boot_ns() will also save the additional conversion to nanoseconds.

2017-12-05iwlwifi: mvm: make init_dbg effective only on failureLiad Kaufman
If FW loads without a problem, leaving init_dbg on can cause a confusion, since the user won't necessarily remember it is still turned on, and there are flows in which everything continues as usual, only without stopping the device after INIT, even if there is no FW assert. On 22000 HW, for instance, this causes a warning, since the paging is getting initialized twice. Solve the issue by making this module param effective only if the FW indeed asserts during INIT.

Debugfs hooks will be still available for reading the current rate/statistics and setting a fixed rate. The old API is supported so far, though both APIs cannot be used simultaneously.

2017-12-05iwlwifi: mvm: avoid dumping assert log when device is stoppedSara Sharon
We might erroneously get to error dumping code when the device is already stopped. In that case the driver will detect a defective value and will try to reset the HW, assuming it is only a bus issue. The driver than proceeds with the dumping. The result has two side effects: 1. The device won't be stopped again, since the transport status is already stopped, so the device remains powered on while it actually should be stopped. 2. The dump in that case is completely garbaged and useless. Detect and avoid this. It will also make debugging such issues easier.
