Santosh Vernekar 8474f3a02a [SCSI] qla2xxx: Correctly set FCF_TAPE_PRESENT flag based on scsi-device.
In fabric-login based on iop BIT_8 firmware notifies presence of
a FCP2 device and not necessarily a TAPE device.  So instead of
setting FCF_TAPE_PRESENT flag there we set it using
scsi_device->type after mid-layer scan recognises "type" of the
device.

It also adds a new flag FCF_FCP2_DEVICE for any future use.

Anirban Chakraborty eb94114bfd [SCSI] qla2xxx: Fix a bug that clears the interrupt status register for the base queue
The interrupt handler clears the interrupt status register for response
updates in the base queue while working in the multique mode. This could lead
to missing interrupt for async events, mail box completions etc. as these are
also handled in the base queue.  The fix ensures that the interrupt bit is not
cleared for response updates in the ISR when the driver is working in
multiqueue mode.

Alexey Dobriyan 405f55712d headers: smp_lock.h redux
* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)
