sd: Disable support for 256 byte/sector disks

2015-06-06T15:19:39+00:00

commit 74856fbf441929918c49ff262ace9835048e4e6a upstream.

256 bytes per sector support has been broken since 2.6.X,
and no-one stepped up to fix this.
So disable support for it.

storvsc: Set the SRB flags correctly when no data transfer is needed

2015-06-06T15:19:39+00:00

commit dc45708ca9988656d706940df5fd102672c5de92 upstream.

Set the SRB flags correctly when there is no data transfer.  Without this
change some IHV drivers will fail valid commands such as TEST_UNIT_READY.

qla2xxx: remove redundant declaration in 'qla_gbl.h'

2015-06-06T15:19:31+00:00

commit 9493c2422cae272d6f1f567cbb424195defe4176 upstream.

Remove 2 redundant extern inline functions: qla8044_set_qsnt_ready() and
qla8044_need_reset_handler(). At present, within upstream next kernel
source code, they are only used within "drivers/scsi/qla2xxx/qla_nx2.c".

3w-sas: fix command completion race

2015-05-13T12:16:58+00:00

commit 579d69bc1fd56d5af5761969aa529d1d1c188300 upstream.

The 3w-sas driver needs to tear down the dma mappings before returning
the command to the midlayer, as there is no guarantee the sglist and
count are valid after that point.  Also remove the dma mapping helpers
which have another inherent race due to the request_id index.

mvsas: fix panic on expander attached SATA devices

2015-05-06T19:59:19+00:00

commit 56cbd0ccc1b508de19561211d7ab9e1c77e6b384 upstream.

mvsas is giving a General protection fault when it encounters an expander
attached ATA device.  Analysis of mvs_task_prep_ata() shows that the driver is
assuming all ATA devices are locally attached and obtaining the phy mask by
indexing the local phy table (in the HBA structure) with the phy id.  Since
expanders have many more phys than the HBA, this is causing the index into the
HBA phy table to overflow and returning rubbish as the pointer.

mvs_task_prep_ssp() instead does the phy mask using the port properties.
Mirror this in mvs_task_prep_ata() to fix the panic.

Kernel panic was happening as iscsi_host_remove() was called on
a host which was not yet added.
