1ccde7004f scsi: hpsa: use correct DID_NO_CONNECT hostbyte
NOT_READY is a sense key, not a legit scsi hostbyte value. Use

669f044170 scsi: srp_transport: Move queuecommand() wait code to SCSI core
Additionally, rename srp_wait_for_queuecommand() into
scsi_wait_for_queuecommand() and add a comment about the queuecommand()
call from scsi_send_eh_cmnd().

Note: this patch changes scsi_internal_device_block from a function that
did not sleep into a function that may sleep. This is fine for all
callers of this function:

* scsi_internal_device_block() is called from the mpt3sas device while
  that driver holds the ioc->dm_cmds.mutex. This means that the mpt3sas
  driver calls this function from thread context.
* scsi_target_block() is called by __iscsi_block_session() from
  kernel thread context and with IRQs enabled.
* The SRP transport code also calls scsi_target_block() from kernel
  thread context while sleeping is allowed.
* The snic driver also calls scsi_target_block() from a context from
  which sleeping is allowed. The scsi_target_block() call namely occurs
  immediately after a scsi_flush_work() call.

e58566b1b1 qlogicpti: Fix compiler warnings
qlogicpti uses '__u32' for dma handle while invoking kernel DMA APIs,
instead of using dma_addr_t. This hasn't caused any 'incompatible
pointer type' warning on SPARC because until now dma_addr_t is of
type u32. However, recent changes in SPARC ATU (iommu) enabled 64bit
DMA and therefore dma_addr_t became of type u64. This makes
'incompatible pointer type' warnings inevitable.

e.g.
drivers/scsi/qlogicpti.c: In function ‘qpti_map_queues’:
drivers/scsi/qlogicpti.c:813: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type
./include/linux/dma-mapping.h:445: note: expected ‘dma_addr_t *’ but argument is of type ‘__u32 *’
drivers/scsi/qlogicpti.c:822: warning: passing argument 3 of ‘dma_alloc_coherent’ from incompatible pointer type
./include/linux/dma-mapping.h:445: note: expected ‘dma_addr_t *’ but argument is of type ‘__u32 *’

For the record, qlogicpti never executes on sun4v. Therefore even
though 64bit DMA is enabled on SPARC, qlogicpti continues to use
legacy iommu that guarantees DMA address is always in 32bit range.

This patch resolves aforementioned compiler warnings.

2319f847a8 scsi: lpfc: fix oops/BUG in lpfc_sli_ringtxcmpl_put()
The BUG_ON() recently introduced in lpfc_sli_ringtxcmpl_put() is hit in
the lpfc_els_abort() > lpfc_sli_issue_abort_iotag() >
lpfc_sli_abort_iotag_issue() function path [similar names], due to
'piocb->vport == NULL':

	BUG_ON(!piocb || !piocb->vport);

This happens because lpfc_sli_abort_iotag_issue() doesn't set the
'abtsiocbp->vport' pointer -- but this is not the problem.

Previously, lpfc_sli_ringtxcmpl_put() accessed 'piocb->vport' only if
'piocb->iocb.ulpCommand' is neither CMD_ABORT_XRI_CN nor
CMD_CLOSE_XRI_CN, which are the only possible values for
lpfc_sli_abort_iotag_issue():

    lpfc_sli_ringtxcmpl_put():

        if ((unlikely(pring->ringno == LPFC_ELS_RING)) &&
           (piocb->iocb.ulpCommand != CMD_ABORT_XRI_CN) &&
           (piocb->iocb.ulpCommand != CMD_CLOSE_XRI_CN) &&
            (!(piocb->vport->load_flag & FC_UNLOADING)))

    lpfc_sli_abort_iotag_issue():

        if (phba->link_state >= LPFC_LINK_UP)
                iabt->ulpCommand = CMD_ABORT_XRI_CN;
        else
                iabt->ulpCommand = CMD_CLOSE_XRI_CN;

So, this function path would not have hit this possible NULL pointer
dereference before.

In order to fix this regression, move the second part of the BUG_ON()
check prior to the pointer dereference that it does check for.

For reference, this is the stack trace observed. The problem happened
because an unsolicited event was received - a PLOGI was received after
our PLOGI was issued but not yet complete, so the discovery state
machine goes on to sw-abort our PLOGI.

c70f1fb755 scsi: hisi_sas: alloc queue id of slot according to device id
Currently slots are allocated from queues in a round-robin fashion.
This causes a problem for internal commands in device mode. For this
mode, we should ensure that the internal abort command is the last
command seen in the host for that device. We can only ensure this when
we place the internal abort command after the preceding commands for
device that in the same queue, as there is no order in which the host
will select a queue to execute the next command.

This queue restriction makes supporting scsi mq more tricky in
the future, but should not be a blocker.

Note: Even though v1 hw does not support internal abort, the
      allocation method is chosen to be the same for consistency.

ab677ff4ad cxgb4: Allocate Tx queues dynamically
Allocate resources dynamically for Upper layer driver's (ULD) like
cxgbit, iw_cxgb4, cxgb4i and chcr. The resources allocated include Tx
queues which are allocated when ULD register with cxgb4 driver and freed
while un-registering. The Tx queues which are shared by ULD shall be
allocated by first registering driver and un-allocated by last
unregistering driver.

208da78e8e scsi: libfc: fix seconds_since_last_reset miscalculation
Commit 540eb1eef0ab ("scsi: libfc: fix seconds_since_last_reset calculation")
removed the use of 'struct timespec' from fc_get_host_stats(). This broke the
output of 'fcoeadm -s' after kernel 4.8-rc1.

a0f4bd7f2a scsi: fc: move FC transport's bsg code to bsg-lib
Now that all conversions are done, move the FibreChannel bsg code over
to the bsg library.

This patch is derived from work done by Mike Christie in 2011 [1] but
only the iscsi parts got merged back then.

Export fc_bsg_jobdone so drivers can use it directly instead of doing
the round-trip via struct fc_bsg_job::job_done() and use it in the

bsg_job_done.

As we've converted all LLDDs over to use fc_bsg_jobdone() directly, we
can remove the function pointer from struct fc_bsg_job as well.

af15769ffa scsi: mvsas: fix command_active typo
gcc-7 notices that the condition in mvs_94xx_command_active looks
suspicious:

drivers/scsi/mvsas/mv_94xx.c: In function 'mvs_94xx_command_active':
drivers/scsi/mvsas/mv_94xx.c:671:15: error: '<<' in boolean context, did you mean '<' ? [-Werror=int-in-bool-context]

This was introduced when the mv_printk() statement got added, and leads
to the condition being ignored. This is probably harmless.

Changing '&&' to '&' makes the code look reasonable, as we check the
command bit before setting and printing it.
