The patch below converts the #ifndef SYMBOL / #define SYMBOL / #endif symbol
constructs in the SCST source code into one of the following:
* These three lines are removed entirely if the symbol definition is present in
  the Linux 2.6.18 source tree.
* The definition has been made unconditional if the symbol definition is not yet
  present in the 2.6.31 source tree.
* Converted the definition into #if LINUX_VERSION_CODE < KERNEL_VERSION(...) /
  #define SYMBOL / #endif if a definition for the symbol has been added between
  kernel versions 2.6.18 and 2.6.31.

The patch below has been tested by veryfing whether the SCST tree still
compiles on RHEL 5.4 and by verifying the output of the following command:

  for ((i=24;i<=31;i++)); do scripts/run-regression-tests 2.6.$i; done

(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

Close this window by enabling RISC interrupts after the host has
been registered with the SCSI midlayer.
