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.

- Exclude the put_page_callback patch.
- Enable #define GENERATING_UPSTREAM_PATCH.

during the nightly build the qla2x00t code will only be checked with
checkpatch and sparse for the 2.6.26 kernel.

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",
> ...
>
> message yet.
>
> 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.

applied changes did not have any effect, I'm reverting this commit.

- Moved qla2x00t patch generation code from qla2x00t/Makefile to
qla2x00t/extract-qla2xxx-orig and qla2x00t/generate-in-tree-patches.
Restored qla2x00t/Makefile to r1104.
- scripts/run-regression-tests now passes the full kernel version (including
patch level) to scripts/generate-kernel-patch.
- scripts/generate-kernel-patch can now generate patches for the files
in drivers/scsi/qla2xxx for any kernel version instead of only 2.6.26.8.
