Andrew Vasquez 3fe7cfb910 [SCSI] qla2xxx: Check alternate 'reason' code during GPSC status handling.
Some switches return 0x09 (Command not supported) as the reason
code for GPSC failure.  Check for this code, and disable
additional GPSC queries if found.

Andrew Vasquez 7d232c745e [SCSI] qla2xxx: Add Flash Descriptor Table layout support.
The Flash Descriptor Table (FDT) present on many recent HBAs
encodes flash accessing characteristics of the flash-part used on
the HBA.  Use this information during flash manipulation (writes)
rather than using specific hard-coded values based on queried
manufacturer and device IDs.

To support AEN (and additional forthcoming features), we also

James Bottomley 2f3edc6936 [SCSI] transport_class: BUG if we can't release the attribute container
Every current transport class calls transport_container_release but
ignores the return value.  This is catastrophic if it returns an error
because the containers are part of a global list and the next action of
almost every transport class is to free the memory used by the
container.

Fix this by making transport_container_release a void, but making it BUG
if attribute_container_release returns an error ... this catches the
root cause of a system panic much earlier.  If we don't do this, we get
an eventual BUG when the attribute container list notices the corruption
caused by the freed memory it's still referencing.

Also made attribute_container_release __must_check as a reminder.

James Bottomley fa8e36c39b [SCSI] fix barrier failure issue
Currently, if the barrier command fails, the error return isn't seen
by the block layer and it proceeds on regardless.  The problem is that
SCSI always returns no error for REQ_TYPE_BLOCK_PC ... it expects the
submitter to pick the errors out of req->errors, which the block
barrier functions don't do.

Since it appears that the way SG_IO and scsi_execute_request() work
they discard the block error return and always use req->errors, the
best fix for this is to have the SCSI layer return an error to block
if one actually occurred (this also allows us to filter out spurious
errors, like deferred sense).

This patch is a bug fix that will need backporting to stable, but it's
also quite a big change and in need of testing, so we'll incubate in
the main kernel tree and backport at the -rc2 or so stage if no
problems turn up.

Martin Peschke b75db73159 [SCSI] zfcp: Add qtcb dump to hba debug trace
This patch adds per request hardware debugging data to the trace
record which is written per request. It's a replacement for some sad
kernel message based debugging code. Considering the amount of trace
data, printk() is not suitable for this stuff. Writing binary traces
is more efficient. In addition we got all information in one place.

The QTCB trace data is only dumped for requests other than SCSI
requests.  Otherwise we would flood the trace ring buffer. We are
mostly interested in non-SCSI, recovery related requests here anyway.

This patch also works around a known hardware bug. It truncates QTCB
traces so that we do not save unused areas of the hardware trace.

James Bottomley b8e3d3aeab [SCSI] mpt fusion: fix up msi_enable in mpt_suspend
There's a problem with the combination of the upstream power
management fixes and the enabling of MSI by default in that the
suspend path still uses the global variable.  Convert it to check
ioc->msi_enable.
