If anyone has any objections, please let me know. ------------------ From: Giovanni Cabiddu commit 2c4e8b228733bfbcaf49408fdf94d220f6eb78fc upstream. During a warm reset via kexec, the system bypasses the driver removal sequence, meaning that the remove() callback is not invoked. If a QAT device is not shutdown properly, the device driver will fail to load in a newly rebooted kernel. This might result in output like the following after the kexec reboot: QAT: AE0 is inactive!! QAT: failed to get device out of reset dh895xcc 0000:3f:00.0: qat_hal_clr_reset error dh895xcc 0000:3f:00.0: Failed to init the AEs dh895xcc 0000:3f:00.0: Failed to initialise Acceleration Engine dh895xcc 0000:3f:00.0: Resetting device qat_dev0 dh895xcc 0000:3f:00.0: probe with driver dh895xcc failed with error -14 Implement the shutdown() handler that hooks into the reboot notifier list. This brings down the QAT device and ensures it is shut down properly.
