This patch fixes DMA bugs on x86-64 and ia64 machines.  The driver was
using commands that only support 32bit addresses in places that could
return 64bit addresses.  One place was DMAing off the stack.  The other
place was causing problems on x86-64 machines by calling pci_map()
functions on a region allocated by pci_alloc_consistent().

This patch fixes two minor bugs.  It allows zero length write commands
through to devices.  It also prevents the writing of any  '\0'
characters at the end of version numbers to ips's /proc/scsi files.

This is the qlogic driver version 8.00.00b7 with the ioctl and failover code stripped
out and a few associated fixes put in.

From: "Randy.Dunlap" <rddunlap@osdl.org>

The problem is that the detect function requests an IO region
of 16 bytes (at least when a command line override parameter is
used) but the release function only tries to release 8 bytes,
and this request isn't done because it doesn't match any allocated
IO region.  [NCR53C400 extensions are not enabled, so
NCR5380_region_size is 8, not 16, but the request uses
NCR5380_region_size regardless.]

Fix: save the allocated region size in instance->n_io_ports and release
   that size only;

Thanks for this report; you uncovered a real bug.  Actually two real
bugs; one is that parisc is not discarding the .init.text and .exit.text
sections (so I didn't notice this bug) and the other is that sym_detach
is marked __devexit, yet called from a __devinit function.

I got the following compile error when trying to compile this driver
statically into a kernel with hotplug enabled:


<--  snip  -->

...
drivers/scsi/qla1280.c:4849: error: `qla1280_remove_one' undeclared here

<--  snip  -->


Since I don't see a good reason why qla1280_remove_one is #ifdef'ed out
in the non-modular case the patch below fixes this problem by removing
two #ifdef's.

Fix:

drivers/scsi/aacraid/aachba.c:1409: warning: `flag' might be used uninitialized in this function

Usually, the mid layer ends the block tag (if one was in use)
early to release the resources.  However, things like sg and st
don't go through the code path that does the release, so put a
fallback release in __scsi_release_request() for them.

Attached patch removed the references to the legacy stuff from the
driver.

I'm not sure if that is all that needs to be done though, and I could
only test it for the non-pcmcia case, but that works here.

Sorry Adrian, here is a patch renaming TIMEOUT to TIMEOUT_ERROR.  Still
not a good name for the usage in SCSI core, but it does not conflict, and
matches the other names for the IO completion results (SUCCESS, FAILED,
etc., they and others should really be prefixed with at least SCSI).

eata does not use the TIMEOUT it defines, but there are enough defines of
TIMEOUT that it could be a problem in other drivers.

Only compile tested for eata driver.

This patch fixes a potential memory leak in scsi_alloc_sdev.

If slave_alloc kmallocs memory and the get_device() (around line 245)
fails then we goto the error path.  The error path never calls
slave_destroy.

The attached patch adds a few error checks for the pci dma_mask setting
routines, which after all can fail and thus need their return code
checked.

I am attaching the latest version of the qla1280 driver for inclusion in
the next 2.6.x release. It is mostly based on Christoph's cleanup work
and a couple of changes of my own. I don't know if it is too late for
2.6.1, but otherwise it would be nice to get it into 2.6.2.

I have built and tested this using 2.6.0-test11 on an ia64, but I don't
think there were any major SCSI changes since then.
