commit 628c2893d44876ddd11602400c70606ade62e129 upstream.

The ene_usb6250 sub-driver in usb-storage does USB I/O to buffers on
the stack, which doesn't work with vmapped stacks.  This patch fixes
the problem by allocating a separate 512-byte buffer at probe time and
using it for all of the offending I/O operations.

commit 674aea07e38200ea6f31ff6d5f200f0cf6cdb325 upstream.

This device gives the following error on detection.
xhci_hcd 0000:00:11.0: ERROR Transfer event for disabled endpoint or
incorrect stream ring

The same error is not seen when it is added to unusual_device
list with US_FL_NO_REPORT_OPCODES passed.

commit 2ce9d2272b98743b911196c49e7af5841381c206 upstream.

Some code (all error handling) submits CDBs that are allocated
on the stack.  This breaks with CB/CBI code that tries to create
URB directly from SCSI command buffer - which happens to be in
vmalloced memory with vmalloced kernel stacks.

Let's make copy of the command in usb_stor_CB_transport.

commit 593224ea77b1ca842f45cf76f4deeef44dfbacd1 upstream.

Commit 198de51dbc34 ("USB: uas: Limit qdepth at the scsi-host level")
removed the scsi_change_queue_depth() call from uas_slave_configure()
assuming that the slave would inherit the host's queue_depth, which
that commit sets to the same value.

This is incorrect, without the scsi_change_queue_depth() call the slave's
queue_depth defaults to 1, introducing a performance regression.

This commit restores the call, fixing the performance regression.

Add a new NO_REPORT_LUNS quirk and set it for Seagate drives with
an usb-id of: 0bc2:331a, as these will fail to respond to a
REPORT_LUNS command.

Commit 64d513ac31bd ("scsi: use host wide tags by default") causes
the SCSI core to queue more commands then we can handle on devices with
multiple LUNs, limit the queue depth at the scsi-host level instead of
per slave to fix this.

commit 55ff8cfbc4e12a7d2187df523938cc671fbebdd1 upstream.

The uas driver can never queue more then MAX_CMNDS (- 1) tags and tags
are shared between luns, so there is no need to claim that we can_queue
some random large number.

Not claiming that we can_queue 65536 commands, fixes the uas driver
failing to initialize while allocating the tag map with a "Page allocation
failure (order 7)" error on systems which have been running for a while
and thus have fragmented memory.

Pull final round of SCSI updates from James Bottomley:
 "Sorry for the delay in this patch which was mostly caused by getting
  the merger of the mpt2/mpt3sas driver, which was seen as an essential
  item of maintenance work to do before the drivers diverge too much.
  Unfortunately, this caused a compile failure (detected by linux-next),
  which then had to be fixed up and incubated.

  In addition to the mpt2/3sas rework, there are updates from pm80xx,
  lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus
  an assortment of changes including some year 2038 issues, a fix for a
  remove before detach issue in some drivers and a couple of other minor
  issues"

* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: (141 commits)
  mpt3sas: fix inline markers on non inline function declarations
  sd: Clear PS bit before Mode Select.
  ibmvscsi: set max_lun to 32
  ibmvscsi: display default value for max_id, max_lun and max_channel.
  mptfusion: don't allow negative bytes in kbuf_alloc_2_sgl()
  scsi: pmcraid: replace struct timeval with ktime_get_real_seconds()
  mvumi: 64bit value for seconds_since1970
  be2iscsi: Fix bogus WARN_ON length check
  scsi_scan: don't dump trace when scsi_prep_async_scan() is called twice
  mpt3sas: Bump mpt3sas driver version to 09.102.00.00
  mpt3sas: Single driver module which supports both SAS 2.0 &amp; SAS 3.0 HBAs
  mpt2sas, mpt3sas: Update the driver versions

This patch changes the !blk-mq path to the same defaults as the blk-mq
I/O path by always enabling block tagging, and always using host wide
tags.  We've had blk-mq available for a few releases so bugs with
this mode should have been ironed out, and this ensures we get better
coverage of over tagging setup over different configs.
