I noticed a stream of errors from the IPR driver while doing
IOMMU fault injection. Rate limit the errors so we don't clog
up the console and logfiles.

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.)

The bit-2-doorbell reset method seemed to cause (survivable) NMIs
on some systems and (unsurvivable) IOCK NMIs on some G7 servers.
Firmware guys implemented a new doorbell method to alleviate these
problems triggered by bit 5 of the doorbell register. We want to
use it if it's available.

When waiting for the board to become "not ready"
don't print a message saying "waiting for board to
become ready" (possibly followed by a message saying
"failed waiting for board to become not ready". Instead,
it should be "waiting for board to reset" and "failed
waiting for board to reset."

Detect failure of controller reset by noticing if the 32 bytes of
"driver version" we store on the hardware in the config table
fail to get zeroed out. Previously we noticed if the controller
did not transition to "simple mode", but this did not detect reset
failure if the controller was already in simple mode prior to
the reset attempt (e.g. due to module parameter hpsa_simple_mode=1).

core) support
This is a comprehensive patch for FC-FC4 provider. tcm_fc is a FC-FC4
provider which glues target core (TCM) with Fiber channel library
(libfc). tcm_fc uses existing FC4 provider hooks from Fiber channel
library. This Fiber channel library is used by FCoE (transport - FC
over Ethernet) protocol driver as well.
Combination of modules such as Fiber channel library, tcm_fc, TCM
target core, and FCoE protocol driver enables functional FCoE target.
This patch includes initial commit for tcm_fc plus additional
enhancement, bug fixes.
This tcm_fc module essentially contains 3 entry points such as "prli",
"prlo", "recv". When process login request (ELS_PRLI) request is
received, Fiber channel library (libfc) module calls passive providers
(FC-FC4, tcm_fc) (if any registered) "prli" function. Likewise when
LOGO request is received, "prlo" function of passive provider is
invoked by libfc. For all other request (e.g. any read/write, task
management, LUN inquiry commands), "recv" function of passiver
provider is invoked by libfc. Those passive providers "prli, prlo,
recv" functions interact with TCM target core for requested operation.
This module was primarily developed by "Joe Eykholt" and there were
significant contributions from the people listed under signed-off.

The code currently computes an offset into a dma_alloc_coherent() area
on the assumption that the alignment is imprecise. In fact, the API

I removed outer loops in ...wait_msgint_ready the sleeptime and
retrycount are in fact never changed so I changed them into
defines. In arcmsr_flush_hba_cache is a loop removed, which printed
the same printk 100 times, one line in log is enough I think. The
arcmsr_sleep_for_bus_reset has lost a functionality with the latest
patches, The only thing the function does is a long sleep, so it's
replaced with a ssleep.

On systems with very large numbers (> 1600 or so) of SCSI devices,
cat /proc/scsi/scsi ends up failing with -ENOMEM. This is due to
the show routine simply iterating over all of the devices with
bus_for_each_dev(), and trying to dump all of them into the buffer
at the same time. On my test system (using scsi_debug with 4064 devices),
the output ends up being ~ 632k, far more than kmalloc will typically allow.
This patch defines its own seq_file opreations to iterate over the scsi
devices.The result is that each show() operation only dumps ~ 180 bytes
into the buffer at a time so we don't run out of memory.
If the "Attached devices" header isn't required, we can dump the
sfile->private bit completely.

This patch fixes an issue seen where an event occurs
which causes the ibmvscsi driver to reset its CRQ. Upon
re-registering its CRQ, it receives H_CLOSED, indicating
the Virtual I/O Server is not yet ready to receive commands.
This resulted in the ibmvscsi driver essentially offlining
the adapter and not recovering. The fix is to re-enable
our interrupt so that when the Virtual I/O server is ready
and sends a CRQ init, we will be able to receive it and
resume initialization of the VSCSI adapter.

Currently the size of the dump generated by the driver is limited
in 4MB, which is insufficient to gather much useful data from the
new 64 bit adapters.
This patch makes the needed changes to increase the dump limit
for the 64 bit adapters to 32MB, or even to a bigger value in the
future, but keeping the current limitations for the legacy 32 bit
adapters.

The SCSI ALUA handler currently fails to attach to devices
reporting an UNAVAILABLE/OFFLINE AAS. But given that an
UNAVAILABLE/OFFLINE AAS can transition to other states
like ACTIVE/OPTIMIZED, ACTIVE/NON-OPTIMIZED, etc. as per
SPC4, this ALUA handler behavior should be rectified so
as to attach to devices which also report an
UNAVAILABLE/OFFLINE AAS.

fc_remove_host() waits for flushing the workqueue, but it is stuck at flushing
the first work. The first work doesnt complete, because it is waiting for async
layer to complete the IOs. The async layer cannot complete the IO as the
terminate_rport_io for the second work was not called, which will be called
only when the first work completes. Hence the deadlock. To resolve this
deadlock, the workqueue allocation has been modified from
create_singlethread_workqueue() to alloc_workqueue().
In addition, fc_terminate_rport_io() should be called before the
scsi_flush_work() to avoid the similar deadlock as above.

During performance testing on P7 machines it was observed that the interrupt
service routine was doing unnecessary MMIO operations.
This patch rearranges the logic of the routine and moves some of the code out
of the main routine. The result is that there are now fewer MMIO operations in
the performance path of the code.
As a result of the above change, an existing condition was exposed where the
driver could get an "unexpected" hrrq interrupt. The original code would flag
the interrupt as unexpected and then reset the adapter. After further analysis
it was confirmed that this condition can occasionally occur and that the
interrupt can safely be ignored. Additional code in this patch detects this
condition, clears the interrupt and allows the driver to continue without
resetting the adapter.
