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()).

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"

    >
    > 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.

Vladislav Bolkhovitin 647638ebac Fix for problem with 2.6.31 kernel, where blk_rq_append_bio() was un-exported. So, from now scst_exec_req_fifo is again required for pass-through handlers.
