This patch adds a validation step before allowing creation of a new NPIV port.
It checks whether the WWPN passed for the new NPIV port to be created is unique

Host doesnt handle CVL to NPIV instantiated ports correctly.
- As per FC-BB-5 Rev 2 CVLs with no VN_Port descriptors shall be treated as
implicit logout of ALL vn_ports.
- CVL for NPIV ports should be handled before physical port even if descriptor
for physical port appears before NPIV ports

context
Driver was a sending a SEP request during interrupt context which
required to go to sleep.
The fix is to rearrange the code so a fake event
MPT2SAS_TURN_ON_FAULT_LED is fired from interrupt context, then later
during the kernel worker threads processing, the SEP request is issued
to firmware.

* 'devicetree/merge' of git://git.secretlab.ca/git/linux-2.6:
drivercore: revert addition of of_match to struct device
of: fix race when matching drivers
|
|
Commit b826291c, "drivercore/dt: add a match table pointer to struct
device" added an of_match pointer to struct device to cache the
of_match_table entry discovered at driver match time. This was unsafe
because matching is not an atomic operation with probing a driver. If
two or more drivers are attempted to be matched to a driver at the
same time, then the cached matching entry pointer could get
overwritten.
This patch reverts the of_match cache pointer and reworks all users to
call of_match_device() directly instead.

Commit c21e6beb removed our queue request_fn re-enter
protection, and defaulted to always running the queues from
kblockd to be safe. This was a known potential slow down,
but should be safe.
Unfortunately this is causing big performance regressions for
some, so we need to improve this logic. Looking into the details
of the re-enter, the real issue is on requeue of requests.
Requeue of requests upon seeing a BUSY condition from the device
ends up re-running the queue, causing traces like this:
scsi_request_fn()
scsi_dispatch_cmd()
scsi_queue_insert()
__scsi_queue_insert()
scsi_run_queue()
scsi_request_fn()
...
potentially causing the issue we want to avoid. So special
case the requeue re-run of the queue, but improve it to offload
the entire run of local queue and starved queue from a single
workqueue callback. This is a lot better than potentially
kicking off a workqueue run for each device seen.
This also fixes the issue of the local device going into recursion,
since the above mentioned commit never moved that queue run out
of line.

Eliminate duplicate code by refactoring the calls to qla2xxx_read_sfp()
in qla2x00_get_thermal_temp(). This keeps the parameter values separate
from the mailbox register mechanics. This also allows qla2xxx_read_sfp()
to be the sole "spec" for READ SFP semantics.

When reading a single byte using the READ SFP mailbox command, the
single byte of data is returned in MB[1] and not MB[8].
The reason that MB[8] was being used is that the spec was unclear
as it evolved over time; and we have not needed to read a single
byte until recently.

on driver load, if reset_devices is set, and the hard reset
attempts fail, try to bring up the controller to the point that
a command can be sent, and send it a soft reset command, then
after the reset undo whatever driver initialization was done to get
it to the point to take a command, and re-do it after the reset.
This is to get kdump to work on all the "non-resettable" controllers
(except 64xx controllers which can't be reset due to the potentially
shared cache module.)
