Commit e3deec09 incorrectly assumed that the B0 and B1 page lengths were
limited to 32 bytes. The B0 VPD page length is defined to be 64 bytes
when the device supports thin provisioning. B1 is always defined to be
64 bytes.

This uses the scatter-gather chaining feature of Smart Array
controllers. 32 scatter-gather elements are embedded in the
"command list", and the last element in the list may be marked
as a "chain pointer", and point to an additional block of
scatter gather elements. The precise number of scatter gather
elements supported is dependent on the particular kind of
Smart Array, and is determined at runtime by querying the
hardware.

The intent of the scan thread was to allow a UNIT ATTENTION/LUN
DATA CHANGED condition encountered in the interrupt handler
to trigger a rescan of devices, which can't be done in interrupt
context. However, we weren't able to get this to work, due to
multiple such UNIT ATTENTION conditions arriving during the rescan,
during updating of the SCSI mid layer, etc. There's no way to tell
the devices, "stand still while I scan you!" Since it doesn't work,
there's no point in having the thread, as the rescan triggered via
ioctl or sysfs can be done without such a thread.

This patch adds a reboot notifier that will issue a shutdown prepare command
to all adapters. This helps to prevent a problem where the primary adapter can

In tx/mcc polling, napi_complete() is being incorrectly called
before reaping tx completions. This can cause tx compl processing
to be scheduled on another cpu concurrently which can result in a panic.
This if fixed by calling napi complete() after tx/mcc compl processing
