Subject: qla2xxx: Set an rport's dev_loss_tmo value in a consistent manner.
[ Upstream commit 85821c906cf3563a00a3d98fa380a2581a7a5ff1 ]
As there's no point in adding a fixed-fudge value (originally 5
seconds), honor the user settings only. We also remove the
driver's dead-callback get_rport_dev_loss_tmo function
(qla2x00_get_rport_loss_tmo()).

The sysfs intarface is mostly finished. Only initiators-oriented access control not implemented and not all target drivers are updated. Only qla2x00t has been fully updated.

- iSCSI read state machine cleanups
- Fix a race when just freed iSCSI session accessed, because the corresponding SCST session is still being unregistered.

Subject: SCSI: qla2xxx: Defer enablement of RISC interrupts until ISP initialization completes.
commit 048feec5548c0582ee96148c61b87cccbcb5f9be upstream
Josip Rodin noted
(http://article.gmane.org/gmane.linux.ports.sparc/10152) the
driver oopsing during registration of an rport to the
FC-transport layer with a backtrace indicating a dereferencing of
an shost->shost_data equal to NULL. David Miller identified a
small window in driver logic where this could happen:
> Look at how the driver registers the IRQ handler before the host has
> been registered with the SCSI layer.
>
> That leads to a window of time where the shost hasn't been setup
> fully, yet ISRs can come in and trigger DPC thread events, such as
> loop resyncs, which expect the transport area to be setup.
>
> But it won't be setup, because scsi_add_host() hasn't finished yet.
>
> Note that in Josip's crash log, we don't even see the
>
> qla_printk(KERN_INFO, ha, "\n"
> " QLogic Fibre Channel HBA Driver: %s\n"
> " QLogic %s - %s\n"
> " ISP%04X: %s @ %s hdma%c, host#=%ld, fw=%s\n",
> ...

> Which means that the crash occurs between qla2x00_request_irqs()
> and printing that message.
Close this window by enabling RISC interrupts after the host has
been registered with the SCSI midlayer.
