92fff53b71 SCSI misc on 20190306
This is mostly update of the usual drivers: arcmsr, qla2xxx, lpfc,
 hisi_sas, target/iscsi and target/core.  Additionally Christoph
 refactored gdth as part of the dma changes.  The major mid-layer
 change this time is the removal of bidi commands and with them the
 whole of the osd/exofs driver and filesystem.

 "Not a huge amount of changes in this round, the biggest one is that we
  finally have Mings multi-page bvec support merged. Apart from that,
  this pull request contains:

   - Small series that avoids quiescing the queue for sysfs changes that

   - Series of bcache fixes (via Coly)

   - Series of lightnvm fixes (via Mathias)

   - NVMe pull request from Christoph. Nothing major, just SPDX/license

   - BFQ series (Paolo)

   - Save blk-mq cpu -> hw queue mapping, removing a pointer indirection
     for the fast path (Jianchao)

   - fops->iopoll() added for async IO polling, this is a feature that

   - cdrom registration race fix (Guenter)

   - MD pull from Song, two minor fixes.

   - Various documentation fixes (Marcos)

   - Multi-page bvec feature. This brings a lot of nice improvements

45763bf4bc Char/Misc driver patches for 5.1-rc1
Here is the big char/misc driver patch pull request for 5.1-rc1.
 
 The largest thing by far is the new habanalabs driver for their AI
 accelerator chip.  For now it is in the drivers/misc directory but will
 probably move to a new directory soon along with other drivers of this
 type.
 
 Other than that, just the usual set of individual driver updates and
 fixes.  There's an "odd" merge in here from the DRM tree that they asked
 me to do as the MEI driver is starting to interact with the i915 driver,
 and it needed some coordination.  All of those patches have been
 properly acked by the relevant subsystem maintainers.
 
 All of these have been in linux-next with no reported issues, most for
 quite some time.

df49fd0ff8 SCSI fixes on 20190302
Nine small fixes.  The resume fix is a cosmetic removal of a warning
 with an incorrect condition causing it to alarm people wrongly.  The
 other eight patches correct a thinko in Christoph Hellwig's DMA
 conversion series.  Without it all these drivers end up with 32 bit
 DMA masks meaning they bounce any page over 4GB before sending it to
 the controller.  Nowadays, even laptops mostly have memory above 4GB,
 so this can lead to significant performance degradation with all the
 bouncing.

[ 5526.588562] scsi_alloc_sdev: Allocation failure during SCSI scanning, some SCSI devices might not be configured

Looking at the code of scsi_alloc_sdev(), and all the calling contexts,
there seems to be no reason to use GFP_ATMOIC here. All the different
call-contexts use a mutex at some point, and nothing in between that
requires no sleeping, as far as I could see. Additionally, the code that
later allocates the block queue for the device (scsi_mq_alloc_queue())
already uses GFP_KERNEL.

There are similar allocations in two other functions:
scsi_probe_and_add_lun(), and scsi_add_lun(),; that can also be done with
GFP_KERNEL.

Here is the contexts for the three functions so far:

    scsi_alloc_sdev()
        scsi_probe_and_add_lun()
            scsi_sequential_lun_scan()
                __scsi_scan_target()
                    scsi_scan_target()
                        mutex_lock()
                    scsi_scan_channel()
                        scsi_scan_host_selected()
                            mutex_lock()
            scsi_report_lun_scan()
                __scsi_scan_target()
    	            ...
            __scsi_add_device()
                mutex_lock()
            __scsi_scan_target()
                ...
        scsi_report_lun_scan()
            ...
        scsi_get_host_dev()
            mutex_lock()

    scsi_probe_and_add_lun()
        ...

    scsi_add_lun()
        scsi_probe_and_add_lun()
            ...

So replace all these, and give them a bit of a better chance to succeed,
with more chances of reclaim.

6f46f718fc scsi: st: osst: Remove negative constant left-shifts
Negative constant left-shift is undefined behaviour in the C standard, and
as such newer versions of clang (at least) warn against it. GCC supports it
for a long time, but it would be better to remove it and rely on defined
behaviour.

My understanding is "~(-1 << N)" in 2's complement is intended to generate
a bit pattern of zeroes ending with N '1' bits. The same can be achieved by
"(1 << N) - 1" in a well-defined way, so switch to it to remove the
warning.

Tested: building a kernel with generic SCSI tape, and checking basic
operations (mt status, mt eject) on a real LTO unit. Cannot test the osst
driver.

5c17f87abb scsi: ufs-bsg: Allow reading descriptors
Add this functionality, placing the descriptor being read in the actual
data buffer in the bio.

That is, for both read and write descriptors query upiu, we are using the
job's request_payload.  This in turn, is mapped back in user land to the
applicable sg_io_v4 xferp: dout_xferp for write descriptor, and din_xferp
for read descriptor.

4eaa329e33 scsi: ufs-bsg: Change the calling convention for write descriptor
When we had a write descriptor query upiu, we appended the descriptor right
after the bsg request.  This was fine as the bsg driver allows to allocate
whatever buffer we needed in its job request.

Still, the proper way to deliver payload, however small (we only write
config descriptors of 144 bytes), is by using the job request payload data
buffer.

So change this ABI now, while ufs-bsg is still new, and nobody is actually
using it.

Resolution: keep HEAD, and delete the ufshcd_set_vccq_rail_unused() call
and corresponding error-handling code.

Clean up loose ends in a follow-up patch.

60f0187031 introduced a small power optimization: ignore the vccq load
specified in the UFSHC DT node when said host controller is connected to
specific Flash chips (currently, Samsung and Hynix).

Unfortunately, this optimization breaks UFS on systems where vccq powers
not only the Flash chip, but the host controller as well, such as APQ8098
MEDIABOX or MTP8998:

In my opinion, the rationale for the original patch is questionable.  If
neither the UFSHC, nor the Flash chip, require any load from vccq, then
that power rail should simply not be specified at all in the DT.

Working around that fact in the driver is detrimental, as evidenced by the
failure to initialize the host controller on MSM8998.

a83da8a450 scsi: sd: Optimal I/O size should be a multiple of physical block size
It was reported that some devices report an OPTIMAL TRANSFER LENGTH of
0xFFFF blocks. That looks bogus, especially for a device with a
4096-byte physical block size.

Ignore OPTIMAL TRANSFER LENGTH if it is not a multiple of the device's
reported physical block size.

To make the sanity checking conditionals more readable--and to
facilitate printing warnings--relocate the checking to a helper
function. No functional change aside from the printks.

8beb90aaf3 scsi: fcoe: make use of fip_mode enum complete
commit 1917d42d14 ("fcoe: use enum for fip_mode") introduces a separate
enum for the fip_mode that shall be used during initialisation handling
until it is passed to fcoe_ctrl_link_up to set the initial fip_state.  That
change was incomplete and gcc quietly converted in various places between
the fip_mode and the fip_state enum values with implicit enum conversions,
which fortunately cannot cause any issues in the actual code's execution.

clang however warns about these implicit enum conversions in the scsi
drivers. This commit consolidates the use of the two enums, guided by
clang's enum-conversion warnings.

This commit now completes the use of the fip_mode: It expects and uses
fip_mode in {bnx2fc,fcoe}_interface_create and fcoe_ctlr_init, and it calls
fcoe_ctrl_set_set() with the correct values in fcoe_ctlr_link_up().  It
also breaks the association between FIP_MODE_AUTO and FIP_ST_AUTO to
indicate these two enums are distinct.

f3e0269517 scsi: qla2xxx: Avoid PCI IRQ affinity mapping when multiqueue is not supported
This patch fixes warning seen when BLK-MQ is enabled and hardware does not
support MQ. This will result into driver requesting MSIx vectors which are
equal or less than pre_desc via PCI IRQ Affinity infrastructure.

The fix is to check if the hardware does not have Multi Queue capabiltiy,
use pci_alloc_irq_vectors() call instead of pci_alloc_irq_affinity().
