This flag denotes local attachment of the phy. There are two problems
with it:
1) It's actually redundant ... you can get the same information simply
by seeing whether a host is the phys parent
2) we condition a lot of phy parameters on it on the false assumption
that we can only control local phys. I'm wiring up phy resets in the
aic94xx now, and it will be able to reset non-local phys as well.
I fixed 2) by moving the local check into the reset and stats function
of the mptsas, since that seems to be the only HBA that can't
(currently) control non-local phys.

This patch updates the fc transport for the following:
- Addition of a new attribute "system_hostname" which can be
used to set the fully qualified hostname that the fc_host
is attached to. The fc_host can then register this string
as the FDMI-based host name attribute.
Note: for NPIV, a fc_host could be associated with a system which
is not the local system.
- Add the inline function u64_to_wwn(), which is the inverse of the
existing wwn_to_u64() function.
- Slight reorg, just to keep dynamic attributes with each other, etc

Some targets may return slight variations of PQ and PDT to indicate
no LUN mapped. USB UFI setting PDT=0x1f but having reserved bits for
PQ is one example, and NetApp targets returning PQ=1 and PDT=0x1f is
another. Both instances seem like reasonable responses according to
SPC-3 and UFI specs.
The current scsi_probe_and_add_lun() code adds a scsi_device
for targets that return PQ=1 and PDT=0x1f. This causes LUNs of type
"UNKNOWN" to show up in /proc/scsi/scsi when no LUNs are mapped.
In addition, subsequent rescans fail to recognize LUNs that may be
added on the target, unless preceded by a write to the delete attribute
of the "UNKNOWN" LUN.
This patch addresses this problem by skipping over the scsi_add_lun()
when PQ=1,PDT=0x1f is encountered, and just returns
SCSI_SCAN_TARGET_PRESENT.

If the adapter should be in a blinkled (Firmware Assert) state when the
driver loads, we will perform a warm restart of the Adapter Firmware to
see if we can rescue the adapter. Possible causes of a blinkled can
occur on some early release motherboard BIOSes, transitory PCI bus
problems on embedded systems or non-x86 based architectures, transitory
startup failures of early release drives or transitory hardware
failures; some of which can bite the adapter later at runtime. Future
enhancements will include recovery during runtime.
Fixed extra whitespace space issue.

This patch allows the FSACTL_SEND_LARGE_FIB, FSACTL_SENDFIB and
FSACTL_SEND_RAW_SRB ioctl calls into the aacraid driver to be
interruptible. Only necessary if the adapter and/or the management
software has gone into some sort of misbehavior and the system is being
rebooted, thus permitting the user management software applications to
be killed relatively cleanly. The FIB queue resource is held out of the
free queue until the adapter finally, if ever, completes the command.

<0>Kernel panic - not syncing: Corrupt kernel stack, can't continue.
This stack overflow occurred during tests on s390 using zfcp.
Recursion depth for this panic was 19.
Usually recursion between blk_run_queue and a request_fn is avoided
using QUEUE_FLAG_REENTER. But this does not help if the scsi stack
tries to flush the starved_list of a scsi_host.
Limit recursion depth when flushing the starved_list
of a scsi_host.

- Replace scsi_device_types array API with scsi_device_type function API.
Gets rid of a lot of common code, as well as being easier to use.
- Add the new device types in SPC4 r05a, and rename some of the older ones.
- Reformat the printing of inquiry data; now fits on one line and
includes PQ.
I think I've addressed all the feedback from the previous versions. My
current test box prints:

The sysfs files in arcmsr are non-standard in that they aren't simple
filename value pairs, the values actually contain preceeding text which
would have to be parsed. The idea of sysfs files is that the file name
is the description and the contents is a simple value.
Fix up arcmsr to conform to this standard.

Sometimes the logic to handle AGPx8->AGPx4 fallback failed, as can
be seen in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=197346
The failures occured if the bridge was in AGPx8 mode, but the
user hadn't specified a mode in their X config. We weren't
setting the mode to the highest mode capable by the video card+bridge
(as we do in the AGPv2 case), which was leading to all kinds of
mayhem including us believing that after falling back from AGPx8, that
we couldn't do x4 mode (which is disastrous in AGPv3, as those are
the only two modes possible).

AGP keeps its own copy of the protection_map, upcoming DRM changes will
also require access to this map from modules.

As there are other places that call cpufreq_update_policy without
the hotplug lock, it seems better to keep the hotplug locking
at the lower level for the time being until this is revamped.
