cciss: cleanup interrupt_not_for_us In the case of MSI/MSIX interrutps, we don't need to check if the interrupt is for us, and in the case of the intx interrupt handler, when checking if the interrupt is for us, we don't need to check if we're using MSI/MSIX, we know we're not.

cciss: separate cmd_alloc() and cmd_special_alloc() cmd_alloc() took a parameter which caused it to either allocate from a pre-allocated pool, or allocate using pci_alloc_consistent. This parameter is always known at compile time, so this would be better handled by breaking the function into two functions and differentiating the cases by function names. Same goes for cmd_free().

cciss: forbid hard reset of 640x boards The 6402/6404 are two PCI devices -- two Smart Array controllers -- that fit into one slot. It is possible to reset them independently, however, they share a battery backed cache module. One of the pair controls the cache and the 2nd one access the cache through the first one. If you reset the one controlling the cache, the other one will not be a happy camper. So we just forbid resetting this conjoined mess. Signed-off-by: NStephen M.

cciss: sanitize max commands Some controllers might try to tell us they support 0 commands in performant mode. This is a lie told by buggy firmware. We have to be wary of this lest we try to allocate a negative number of command blocks, which will be treated as unsigned, and get an out of memory condition. Signed-off-by: NStephen M.

cciss: Fix hard reset code. Smart Array controllers newer than the P600 do not honor the PCI power state method of resetting the controllers. Instead, in these cases we can get them to reset via the "doorbell" register. This escaped notice until we began using "performant" mode because the fact that the controllers did not reset did not normally impede subsequent operation, and so things generally appeared to "work". Once the performant mode code was added, if the controller does not reset, it remains in performant mode. The code immediately after the reset presumes the controller is in "simple" mode (which previously, it had remained in simple mode the whole time). If the controller remains in performant mode any code which presumes it is in simple mode will not work. So the reset needs to be fixed. Unfortunately there are some controllers which cannot be reset by either method. (eg. p800). We detect these cases by noticing that the controller seems to remain in performant mode even after a reset has been attempted. In those cases we ignore the controller, as any commands outstanding on it will result in stale completions. To sum up, we try to do a better job of resetting the controller if "reset_devices" is set, and if it doesn't work, we ignore that controller. Signed-off-by: NStephen M.

The open and release block_device_operations are currently called with the BKL held. In order to change that, we must first make sure that all drivers that currently rely on this have no regressions. This blindly pushes the BKL into all .open and .release operations for all block drivers to prepare for the next step. The drivers can subsequently replace the BKL with their own locks or remove it completely when it can be shown that it is not needed. The functions blkdev_get and blkdev_put are the only remaining users of the big kernel lock in the block layer, besides a few uses in the ioctl code, none of which need to serialize with blkdev_{get,put}. Most of these two functions is also under the protection of bdev->bd_mutex, including the actual calls to ->open and ->release, and the common code does not access any global data structures that need the BKL.
