The basic change is to allow target scans to be done
by generic device (which need only have a scsi host
as a parent).  Also changes most target functions to
take a struct scsi_target instead of the H/C/T numbers.

This patch adds a NOREPORTLUN blacklist flag for a disk made by "WDC"
(Winchester?).  The drive's firmware crashes when it receives REPORT_LUNS,
even though it claims to be SCSI rev 04.

This is an updated and unmangled version of the patch sent in by Martin
Peschke.  Apparently some drives report Hardware Error sense for
problems which do improve after retrying, so the patch retries these
supposedly "unrecoverable" errors for such devices.

In addition to the IBM ESS drive it adds a blacklist entry for the drive
inside the MPIO HS200 Gigabox.

The patch at the end of this message converts the SCSI tape driver to support
also descriptor based sense data. Test for deferred sense data have been added
in a couple of places and the EOM tests have been unified. Some tests have been
simplified but the patch is not meant to change the current behavior. The
patch is against 2.6.11-rc4 and has been tested to some extent.

The patch also includes the msleep_interruptible change from from kernel
janitors.

Thanks to Doug Gilbert for doing a first version of this sense data
conversion.

reading the /proc/scsi/qla1280/* files can easily corrupt kernel memory.

As the feature is deprecated, and the qla1280 implementation doesn't
return very usefull implementation but is so buggy that any serious
user would have noticed we just remove it.

This patch fixes one of Christroph's fixme comments in the SCSI midlayer.

The selection of the serial number and pid for commands was done
by a global variable and not SMP safe. The race was not very
serious because it was only used for error handling, but it's
still better to fix it.

I audited all the drivers and none seemed to use them
for anything interesting, so I just made it a per host counter
protected by host lock.

(in fact they could be probably removed because they only see
to be used as a flag in exception handling and for debugging.
The patch would be unfortunately quite big because a lot
of driver printks use them)

This should be slight faster on SMP too because the cache line of
the counter won't bounce around the machine.

1) mptscsih.c: I have changed task management 
requests so they complete in same thread before returning
to os.  I removed the TMtimer code.  
 
(2) mptctl.c: I have deleted both TMtimer and timer code. Replaced
with wait_event_interruptible_timeout.  So commands are now
completed in same thread.  
 
(3) mptctl_do_fw_download - nasty polling of global parameters
that are set in contents of interrupt handler(mptctl_reply), now using

Not that low-level code really tends to care, but since loff_t is
a signed 64-bit entity and size_t is unsigned (and potentially
64-bit), mixing the two isn't very well-defined.. 

The actual user copy will do them too, but only for the
range that ends up being actually copied. That hides
bugs when the range has been clamped by file size or other
issues.
