These are the extra 'Integrated Device Function' SMBus controllers found
on the Patsburg chipset. Mention the absence of slave mode support.

It's poor form to keep driver state in global variables rather than
per-instance. It never really mattered in practice when there was only
one controller on the chipset, but the latest chipsets do have more
than one controller, so now we care.

Considering following scenario - the touch is present on the screen
at the beginning of the last conversion sequence, but by the time
the last sequence is finished, the finger is lift off. The AD7879 data
available interrupt signals (DAV) completion, however some X,Y values
are not valid because the screen inputs were floating during the
acquisition.
The AD7877 acts differently here, since it only asserts DAV if the
touch is still present when the conversion sequence finished.
Based on the fact that this can only happen in the last sample of the
repeated conversion sequence, we simply skip the last (short glitches
are filtered by the AD7879 internal median and average filters).
This doesn't cause noticeable side effects, since the minimum conversion
interval is 9.44ms. We receive ~100 waypoint samples per second, so we
simply delay the result by 9.44ms.
We also reject samples where pressure is greater than pressure_max.

sense_buffer is both a direct member of struct pmcraid_cmd as well as
an indirect one via an anonymous union and struct. Fix this clash by
eliminating the direct member in favour of the anonymous struct/union
one. The name duplication apparently isn't noticed by gcc versions
earlier than 4.4

If the command has timedout then the block layer has called
blk_mark_rq_complete. If qla4xxx_cmd_wait is then called
from qla4xxx_eh_host_reset, we will always fail, because if
the driver calls scsi_done then the the block layer will fail
at blk_complete_request's blk_mark_rq_complete call instead of
calling the normal completion path including the function,
blk_queue_end_tag, which releases the tag.

This is a trivial addition to the SG API that can receive kernel
pointers. It is only used by the out-of-tree test module. So
it's immediate need is questionable. For maintenance ease it might
just get in, as it's very small.

This patch adds the Scatter-Gather (sg) API to libosd.
Scatter-gather enables a write/read of multiple none-contiguous
areas of an object, in a single call. The extents may overlap
and/or be in any order.
The Scatter-Gather list is sent to the target in what is called
a "cdb continuation segment". This is yet another possible segment
in the osd-out-buffer. It is unlike all other segments in that it
sits before the actual "data" segment (which until now was always
first), and that it is signed by itself and not part of the data
buffer. This is because the cdb-continuation-segment is considered
a spill-over of the CDB data, and is therefor signed under
OSD_SEC_CAPKEY and higher.
TODO: A new osd_finalize_request_ex version should be supplied so
the @caps received on the network also contains a size parameter
and can be spilled over into the "cdb continuation segment".
Thanks to John Chandy <john.chandy@uconn.edu> for the original
code, and investigations. And the implementation of SG support
in the osd-target.

size to zero.

Adapter Shutdown and Unregistration cleanup
- Correct the logic around hba shutdown. Prior to final reset, the
driver must wait for all XRIs to return from the adapter. Added logic
to poll, progressively slowing the poll rate as delay gets longer.
- Correct behavior around the rsvd1 field in UNREG_RPI_ALL mailbox
completion and final rpi cleanup.
- Updated logic to move pending VPI registrations to their completion
in cases where a CVL may be received while registration in progress.
- Added unreg all rpi mailbox command before unreg vpi.

Added driver logic to detect the last devloss timeout of remote nodes which
was still in use of FCF. At that point, the driver should set the last
in-use remote node devloss timeout flag if it was not already set and should
perform proper action on the in-use FCF and recover of FCF from firmware,
depending on the state the driver's FIP engine is in.
Find eligible FCF through FCF table rescan or the next new FCF event when
FCF table rescan turned out empty eligible FCF, and the successful flogi
into an FCF shall clear the HBA_DEVLOSS_TMO flag, indicating the successful
recovery from devloss timeout.

- Treated firmware matching FCF property with different index as error
- Propagate error returns from lpfc_issue_els_flogi()
- Refactored lpfc_unregister_unused_fcf() to create a post
lpfc_dev_loss_tmo handler call for SLI-4 devices. Allows checking of
fcf after last ndlp released so that fcf can be released if no longer
in use.

FCF_DISCOVERY flag upon succesful completion of flogi.
- Correct setting of altBbCredit value in sparams to correct issue with
logins with remote loop-based devices.

Currently when we receive a CS_RESET as a response for a SCSI command the
driver will return DID_TRANSPORT_DISRUPTED back to the SCSI mid-layer. There
are certain circumstances where this could cause the mid-layer to exhaust all of
its retries if the FC port goes away for a short time. This will result in
commands being prematurly failed. Moving the CS_RESET return code to be
grouped with other link level events will cause the FC transport layer to block
that target's queue thus preventing the premature exhaustion of retries.

Using del_timer_sync() in the qla2x00_ctx_sp_free() function may cause a kernel
panic as it is not interrupt context safe and qla2x00_ctx_sp_free() may be
called from a softirq context. Changing the call from del_timer_sync() to
del_timer() will make the function interrupt context safe.

Add the module parameter ql2xgffidenable to disable/enable the use of the
GFF_ID name server command to prevent non FCP SCSI devices from being added to
the driver's internal fc_port database.

This patch removes the use of the port down retry counter as a mechanism to
update a fcport state. The internal driver counter is a residual carry-over
from pre-FC-transport aware driver inteaction. The ql2xport_down_retry module
parameter and NVRAM set ha->port_down_retry_count remain in order to seed the
fc-host's default dev-loss-tmo.

IRQs are already disabled here so we don't need to disable them again.
But more importantly, the spin_lock_irqsave() overwrites "flags" and
that breaks things when we want to re-enable the IRQs when we call
spin_unlock_irqrestore(&ha->hardware_lock, flags);

An sr device that reports sense data with SK/ASC/ASCQ of 2/4/2 (Not ready,
Logical unit not ready, Initializing command required) will be handled
in sr_drive_status as (2/4/!1) and assumed to be a 'format in progress'
which returns CDS_DISC_OK. The drive will not be made ready in this case.
Prior to 210ba1d1724f5c4ed87a2ab1a21ca861a915f734 sr_drive_status would
have returned CDS_TRAY_OPEN and this results in an START_STOP_UNIT to
close the tray, which resolves the initialization requirement.
This patch adds handling for SK/ASC/ASCQ of 2/4/2 where it will return
CDS_TRAY_OPEN as a means of triggering a START_STOP_UNIT.
This issue is seen on the IBM POWER platform when using a file-backed,
virtual optical device. The device does not support media queries
through the Get Event Status Notification command which could otherwise
trigger a START_STOP_UNIT call to close an open tray.
