Vasily,
I actually didn't forget this. I think it isn't needed. The reason
being
that in scsi.c: scsi_dispatch_command(), where hostt->queuecommand() is
called,
there is a spin_lock_irqsave()/spin_unlock_irqrestore() wrapper in
there, disabling
interrupts.

Hello Adam,
you have fixed recently potential memory corruption, kmap_atomic issue
in 3w-9xxx driver, however it seems for me you have forgotten to fix the
same issue in yet another similar place, in twa_scsiop_execute_scsi()
function.
