After getting the platform shutdown command "VM_CloseAll" response from the firmware, driver was getting configuration IOCTL request from the upper layers and it sends down to firmware. This causes firmware assert issue. This patch fixes the firmware assert issue. During the shutdown, if driver gets commands from the upper layer, driver sends error code to the upper layers.

The Linux aacriad driver fails to detect the case of SG list count=0 on IOCTL pass-through command and cause intermittent fault. The result is the Linux aacriad driver send down IOCTL pass-through command with one not initialized SG list to firmware when receiving SG list count =0 on pass-through command.

Currently when performing a reboot with an ipr adapter, the adapter gets shutdown completely, flushing all write cache, as well as performing a full hardware reset of the card during the shutdown phase of the old kernel. This ensures the adapter is in a fully quiesced state across the reboot. There are scenarios, however, such as when performing kexec, where this full adapter shutdown is not required and not desired, since it can make the reboot process take noticeably longer. This patch adds a module parameter to allow for skipping the full shutdown during reboot. Rather than performing a full adapter shutdown and reset, we simply cancel any outstanding error buffers, place the adapter into a state where it has no memory of any DMA addresses from the old kernel, then disable the device. This significantly speeds up kexec boot, particularly in configurations with multiple ipr adapters.

This effectively reverts commits 85b6c7 ("[SCSI] sd: fix cache flushing on module removal (and individual device removal)" and dc4515ea ("scsi: always increment reference count"). We now never call scsi_device_get from the shutdown path, and the fact that we started grabbing reference there in commit 85b6c7 turned out turned out to create more problems than it solves, and required workarounds for workarounds for workarounds. Move back to properly checking the device state and carefully handle module refcounting.
