rdac hardware handler uses "Subsystem Identifier" from C4 inquiry page
to uniquely identify a storage. The problem with that is that if any
any of the bytes are non-ascii, subsys_id will all be spaces (hex
0x20). This creates lot of problems especially when there are multiple
rdac storages are connected to the server.
Use "Storage Array Unique Identifier" from C8 inquiry page, which is the
world wide unique identifier for the storage array, to uniquely identify
the storage.

The code is changed to support the new dynamic logging infrastructure.
Following are the levels added.
Default is 0 - no logging. 0x40000000 - Module Init & Probe.
0x20000000 - Mailbox Cmnds. 0x10000000 - Device Discovery.
0x08000000 - IO tracing. 0x04000000 - DPC Thread.
0x02000000 - Async events. 0x01000000 - Timer routines.
0x00800000 - User space. 0x00400000 - Task Management.
0x00200000 - AER/EEH. 0x00100000 - Multi Q.
0x00080000 - P3P Specific. 0x00040000 - Virtual Port.
0x00020000 - Buffer Dump. 0x00010000 - Misc.
0x7fffffff - For enabling all logs, can be too many logs.
Setting ql2xextended_error_logging module parameter to any of the above
value, will enable the debug for that particular level.
Do LOGICAL OR of the value to enable more than one level.

This patch adds the dynamic logging framework to the qla2xxx driver.
The user will be able to change the logging levels on the fly i.e.
without load/unload of the driver. This also enables logging to be
enabled for a particular section of the driver such as initialization,
device discovery etc.

During cable pull tests on our 16G FC adapter, we are seeing errors,
typically reads to close targets, which fail due to CRC or framing
errors caused by the cable being pull (return status DID_ERROR).
The adapter detects the error on one of the first frames received,
marks the FC exchange as dead (further frames go to bit bucket) and
signals the host of the error. This action is so quick, and coupled
with fast host CPUs, creates a scenario in which the midlayer sees
the failure and retries the io almost immediately. We've seen link
traces with the retry on the link while the original i/o is still
being processed by the target. We're also seeing the time window
for the "link to pull-apart" and the physical interface to report
disconnected to be in the few millisecond range. Which means, we're
encountering scenarios where the full retry count is exhausted
(all with error) by the midlayer before the link disconnect state
is detected.
We looked at 8G FC behavior and occasionally see the same behavior,
but as the link was slower, it rarely could exhaust all retries
before the link reported disconnect.
What is needed is a slight delay between io retries due to DID_ERROR
to cover this error. It is inappropriate to put this delay in the
driver, as the error is indistinguishable from other link-related errors,
nor does the driver track whether the io is a retry or not. This is also
easier than tracking between-io-error bursts that are seen in this
scenario.
The patch below updates the retry path so that it inserts a delay as
if the target was busy. The busy delay is on the order of 6ms. This
delay is sufficient to ensure the link down condition is reported
before the retry count is exhausted (at most 1 retry is seen).

Currently it's impossible to find out if the host supports
wide SCSI unless you're committed to trawl through syslog.
And it's near impossible to find the actual HBA id, which
is settable for some SCSI HBAs (like aic7xxx).
So export them via sysfs.

USB surprise removal of sr is triggering an oops in
scsi_dispatch_command(). What seems to be happening is that USB is
hanging on to a queue reference until the last close of the upper
device, so the crash is caused by surprise remove of a mounted CD
followed by attempted unmount.
The problem is that USB doesn't issue its final commands as part of
the SCSI teardown path, but on last close when the block queue is long
gone. The long term fix is probably to make sr do the teardown in the
same way as sd (so remove all the lower bits on ejection, but keep the
upper disk alive until last close of user space). However, the
current oops can be simply fixed by not allowing any commands to be
sent to a dead queue.

Some broken devices indicates that media has changed on every
GET_EVENT_STATUS_NOTIFICATION. This translates into MEDIA_CHANGE

trust only the TUR status.

A kernel panic was observed when passing the sc->request->cpu = -1 to

#9 [ffff880011203e88] cnic_service_bnx2x_bh at ffffffffa03cb1b3
The problem lies in the slow path sg_io (and perhaps sg_scsi_ioctl) call to
blk_get_request->get_request/wait->blk_alloc_request->blk_rq_init which
re-initializes the request->cpu to -1. There is no assignment for cpu from
that to the request_fn call to low level drivers.
When this happens, the sc->request->cpu will be using the init value of
-1. This will create a kernel panic when it hits bnx2i because the code
refers it to get the per_cpu variables ptr.
This change is to put in a guard against that and also for cases when
bio affinity/queue completion to the same cpu is not enabled. In those
cases, the request->cpu will remain a -1 also.
This bug was created from commit: b5cf6b63f73abdc051035f0050b367beeb2ef94c
For the case when the blk layer did not setup the request->cpu, bnx2i
will complete the sc with the current CPU of the thread.

Initial analysis of the dangers provided by Keith Thompson in that thread.
There are many more instances of more complicated macros having unnecessary
trailing semicolons, but this pile seems to be all of the cases of simple
values suffering from the problem. (Thus things that are likely to be found
in one of the contexts above, more complicated ones aren't.)

Most of these simple dereference macros are longer than their open coded
equivalent. Deleting enum sci_controller_mode is thrown in for good
measure.

The distinction between scic_sds_ scic_ and sci_ are no longer relevant
so just unify the prefixes on sci_. The distinction between isci_ and
sci_ is historically significant, and useful for comparing the old
'core' to the current Linux driver. 'sci_' represents the former core as
well as the routines that are closer to the hardware and protocol than
their 'isci_' brethren. sci == sas controller interface.
Also unwind the 'sds1' out of the parameter structs.
