mvsas: increase port type detection delay to suit Seagate's 10k6 drive ST3450856SS 0003

2009-01-18T18:35:44+00:00

commit ddccf307a3599e452804e228d8ed30fba578923e upstream.

I increased the delay step by step until loading of mvsas
reliably detected the drive 200 times in sequence. A much better
approach would be to monitor the hardware for some flag which
indicates that port detection has finished, but I do not have any
hardware documentation.

ibmvfc: Improve async event handling

2009-01-18T18:35:43+00:00

commit d2131b33c7e07c2905ee2f2321cc4dae1928c483 upstream.

While doing various error injection testing, such as cable
pulls and target moves, some issues were observed in handling
these events. This patch improves the way these events are handled
by increasing the delay waiting for the fabric to settle and also
changes the behavior of Link Up to break the CRQ to ensure everything
gets cleaned up properly on the VIOS.

ibmvfc: Delay NPIV login retry and add retries

2009-01-18T18:35:43+00:00

commit 1c41fa8288277e76785acb50f52bb2f39509f903 upstream.

Adds a delay prior to retrying a failed NPIV login. This fixes
a scenario if the backing fibre channel adapter is getting reset
due to an EEH event, NPIV login will fail. Currently, ibmvfc
retries three times very quickly, resets the CRQ and tries one
more time. If the adapter is getting reset due to EEH, this isn't
enough time. This adds a delay prior to retrying a failed NPIV
login and also increments the number of retries.

SCSI: eata: fix the data buffer accessors conversion regression

2009-01-18T18:35:28+00:00

commit 20c09df7eb9c92a40e0ecf654b6e8f14c8583b9e upstream.

This fixes the regression introduced by the commit
58e2a02eb18393e76a469580fedf7caec190eb5e (eata: convert to use the
data buffer accessors), reported:

http://marc.info/?t=122987621300006&r=1&w=2

- fix DMA_NONE handling in map_dma()

- this driver can't use scsi_dma_map since host->shost_gendev.parent
is not set properly (it uses scsi_register).

SCSI: aha152x_cs: Fix regression that keeps driver from using shared interrupts

2009-01-18T18:35:28+00:00

commit 58607b30fc0f2230a189500112c7a7cca02804cf upstream.

At some point since 2.6.22, the aha152x_cs driver stopped working and
started erring on load with the following messages:

kernel: pcmcia: request for exclusive IRQ could not be fulfilled.
kernel: pcmcia: the driver needs updating to supported shared IRQ lines.

With the following change, the driver works with shared IRQs.

SCSI: ibmvstgt: move crq_queue_create to the end of initialization

2009-01-14T17:44:05+00:00

commit 57458036af75c6dbb62bee04b3982e92261eddb1 upstream.

Calling crq_queue_create could lead to the creation of a rport. We
need to set up everything before creating a rport. This moves
crq_queue_create to the end of initialization to avoid a race which
causes an oops if lost.

SCSI: dpt_i2o: fix transferred data length for scsi_set_resid()

2008-11-20T22:54:51+00:00

commit df81d2371aeca0f7474f197a3090830899016e39 upstream.

dpt_i2o.c::adpt_i2o_to_scsi() reads the value at (reply+5) which
should contain the length in bytes of the transferred data. This
would be correct if reply was a u32 *. However it is a void * here,
so we need to read the value at (reply+20) instead.

The value at (reply+5) is usually 0xff0000, which is apparently
'large enough' and didn't cause any trouble until 2.6.27 where
