Andrew Vasquez c795c1e4b6 [SCSI] qla2xxx: Explicitly tear-down vports during PCI remove_one().
During internal testing, we've seen issues (hangs) with the
'deferred' vport tear-down-processing typically accompanied with
the fc_remove_host() call.  This is due to the current
implementation's back-end vport handling being performed by the
physical-HA's DPC thread where premature shutdown could lead to
latent vport requests without a processor.

This should also address a problem reported by Gal Rosen
(http://marc.info/?l=linux-scsi&m=121731664417358&w=2) where the
driver would attempt to awaken a previously torn-down DPC thread
from interrupt context by implicitly calling wake_up_process()
rather than the driver's qla2xxx_wake_dpc() helper.  Rather, than
reshuffle the remove_one() device-removal code, during unload,
depend on the driver's timer to wake-up the DPC process, by
limiting wake-ups based on an 'unloading' flag.

Andrew Vasquez a7a28504bf [SCSI] qla2xxx: Correct vport-state management issues during ISP-ABORT.
* Use correct 'ha' to mark a device lost from ISR.
  I/Os will always be returned on the physical-HA.
  qla2x00_mark_device_lost() should be called with the HA bound
  to the fcport.
* Mark *all* devices lost during ISP-ABORT (bighammer).

These fixes correct issues discovered locally where during
link-perturbation and heavy vport-I/O fcport/rport states would
stray and an rport's scsi-target lost (timed-out).

Andrew Vasquez 6390d1f33f [SCSI] qla2xxx: Correct synchronization of software/firmware fcport states.
Greg Wettstein (greg@enjellic.com) noted:

	http://article.gmane.org/gmane.linux.scsi/43409

on a reboot of a previously recognized SCST target, the initiator
driver would be unable to re-recognize the device as a target.
It turns out that prior to the SCST software reloading and
returning it's "target-capable" abilities in the PRLI payload,
the HBA would be re-initialized as an initiator-only type port.
Since initiators typically classify themselves as an FCP-2
capable device, both software and firmware do not perform an
explicit logout during port-loss.  Unfortunately, as can be seen
by the failure case, when the port (now target-capable) returns,
firmware performs an ADISC without a follow-on PRLI, leaving
stale 'initiator-only' data in the firmware's port database.

Correct the discrepancy by performing the explicit logout during
the transport's request to terminate-rport-io, thus synchronizing
port states and ensuring a follow-on PRLI is performed.

Secondly, scheduled rport removal is handled exclusively by the

Which shows that lockdep is detecting the driver's
interrupt-handler is run in both process and interrupt context
with irqs-enabled in the former case.

During init-time and error-recovery (after a RISC reset), the
driver disables interrupts and 'polls' for completions by calling
qla2x00_poll():

	static inline void
	qla2x00_poll(scsi_qla_host_t *ha)
	{
		ha->isp_ops->intr_handler(0, ha);
	}

which in-turn calls the ISP registered interrupt handler.  This
patch corrects it by disabling local interrupts during polling.

Andrew Vasquez 666301e673 [SCSI] qla2xxx: Correct regression in relogin code.
Commit 63a8651f25 ([SCSI] qla2xxx:
Correct infinite-login-retry issue.) introduced a small
regression where a successful relogin would result in an fcport's
loop_id to be incorrectly reset to FC_NO_LOOP_ID.  Only clear-out
loopid, if retries have been 'truly' exhausted.
