This patch will add big endian architecture support to megaraid_sas
driver. The support added is for LSI MegaRAID all generation controllers-
(3Gb/s, 6Gb/s and 12 Gb/s controllers).We have done basic sanity test @ppc64 arch and @x86_64. Additional
testing/observations are welcome.[jejb: fix up rejections]

This patch does a bit of housekeeping for hpsa. Change lowercase alpha hex
digits to uppercase for consistency within the driver. Also moves the P822se
in the tables to keep controllers of each family grouped together.Signed-off-by: Mike Miller

UIC attributes can be set with using DME_SET command for

IACTH(Interrupt aggregation counter threshold) value is allowed
up to 0x1F and current setting value is the maximum.
This value is related with NUTRS(max:0x20) of HCI's capability.
Considering HCI controller doesn't support the maximum, IACTH
setting should be adjusted with possible value.
For that, existing 'ufshcd_config_int_aggr' is split into two part
[reset, configure].Signed-off-by: Seungwon Jeon

Unlike 'GOOD' and 'CHECK CONDITION', other status values in
Response UPIU may or may not contain sense data. That is returning
sense data isn't obvious. So, in this case the Data Segment Length
field should be checked. If a non-zero value, it means that UPIU
has Sense Data in the Data Segment area.Signed-off-by: Seungwon Jeon

Push file descriptor list locking down to per-device locking. Let sg_index_lock
only protect device lookup.

@detached is set under the protection of sg_index_lock. Without getting the
lock, new sfp will be added during sg removal and there is no chance for it
to be picked out. So check with sg_index_lock held in sg_add_sfp().Signed-off-by: Vaughan Cao

Open exclusive check is protected by o_sem, no need sg_open_exclusive_lock.
@exclude is used to record which type of rwsem we are holding.Signed-off-by: Vaughan Cao
Acked-by: Douglas Gilbert
Signed-off-by: James Bottomley -
A race condition may happen if two threads are both trying to open the same sg
with O_EXCL simultaneously. It's possible that they both find fsds list is
empty and get_exclude(sdp) returns 0, then they both call set_exclude() and
break out from wait_event_interruptible and resume open.Now use rwsem to protect this process. Exclusive open gets write lock and
others get read lock. The lock will be held until file descriptor is closed.
This also leads 'exclude' only a status rather than a check mark.Signed-off-by: Vaughan Cao

Commit b90ebc3d5c41c9164ae04efd2e4f8204c2a186f1 ("[SCSI] scsi_debug:
fix logical block provisioning support") fixed several issues with
logical block provisioning support, but it still doesn't properly fix
the cases when unmap_alignment > 0.For example, load scsi_debug module with the following module parameters
and make all blocks mapped by filling the storage with zero.# modprobe scsi_debug lbpu=1 unmap_alignment=1 unmap_granularity=4
# dd if=/dev/zero of=$DEVThen, try to unmap the first unmappable blocks at lba=1, but GET LBA STATUS
unexpectedly reports that the last UNMAP has done nothing.# sg_unmap --lba=1 --num=4 $DEV
# sg_get_lba_status --lba=1 $DEV
descriptor LBA: 0x0000000000000001 blocks: 16383 mappedThe problem is in map_index_to_lba(), which should return the first
LBA which is corresponding to a given index of provisioning map
(map_storep).Signed-off-by: Akinobu Mita
