Pull SCSI fixes from James Bottomley:
"The only core fix is in doc; all the others are in drivers, with the
biggest impacts in libsas being the rollback on error handling and in
ufs coming from a couple of error handling fixes, one causing a crash
if it's activated before scanning and the other fixing W-LUN
resumption"

During adapter reset, ipr device driver blocks config space access but
can't block MMIO access for MSI-X entries. There is very small window:
irqbalance daemon kicks in during adapter reset before ipr driver calls
pci_restore_state(pdev) to restore MSI-X table.
irqbalance daemon reads back all 0 for that MSI-X vector in
__pci_read_msi_msg().
irqbalance daemon:
msi_domain_set_affinity()
->irq_chip_set_affinity_patent()
->xive_irq_set_affinity()
->irq_chip_compose_msi_msg()
->pseries_msi_compose_msg()
->__pci_read_msi_msg(): read all 0 since didn't call pci_restore_state
->irq_chip_write_msi_msg()
-> pci_write_msg_msi(): write 0 to the msix vector entry
When ipr driver calls pci_restore_state(pdev) in
ipr_reset_restore_cfg_space(), the MSI-X vector entry has been cleared
by irqbalance daemon in pci_write_msg_msix().
pci_restore_state()
->__pci_restore_msix_state()
Below is the MSI-X table for ipr adapter after irqbalance daemon kicked
in during adapter reset:
Dump MSIx table: index=0 address_lo=c800 address_hi=10000000 msg_data=0
Dump MSIx table: index=1 address_lo=c810 address_hi=10000000 msg_data=0

IRQ balancing is not required during adapter reset.
Enable "IRQ_NO_BALANCING" flag before starting adapter reset and disable
it after calling pci_restore_state(). The irqbalance daemon is disabled
for this short period of time (~2s).

In 2009, commit c82f63e411f1 ("PCI: check saved state before restore")
changed the behavior of pci_restore_state() such that it became necessary
to call pci_save_state() afterwards, lest recovery from subsequent PCI
errors fails.
The commit has just been reverted and so all the pci_save_state() after
pci_restore_state() calls that have accumulated in the tree are now
superfluous. Drop them.
Two drivers chose a different approach to achieve the same result:
drivers/scsi/ipr.c and drivers/net/ethernet/intel/e1000e/netdev.c set the
pci_dev's "state_saved" flag to true before calling pci_restore_state().
Drop this as well.

Rename .slave_alloc() into .sdev_init() and .slave_destroy() into
.sdev_destroy(). The new names make it clear that these are actions on
SCSI devices. Make this change in the SCSI core, SCSI drivers and also
in the ATA drivers. No functionality has been changed.
This patch has been created as follows:
* Change the text "slave_alloc" into "sdev_init" in all source files
except those in drivers/net/ and Documentation/.
* Change the text "slave_destroy" into "sdev_destroy" in all source
files except those in drivers/net/ and Documentation/.
* Rename lpfc_no_slave() into lpfc_no_sdev().
* Manually adjust whitespace where necessary to restore vertical
alignment (dc395x driver and include/linux/libata.h).

Cassel)
Cadence PCIe controller driver:

was masked incorrectly (Rick Wertenbroek)
Synopsys DesignWare PCIe controller driver:
- Restructure DBI register access to accommodate devices where this
requires Refclk to be active (Manivannan Sadhasivam)
- Remove the deinit() callback, which was only need by the
pcie-rcar-gen4, and do it directly in that driver (Manivannan
Sadhasivam)
- Add dw_pcie_ep_cleanup() so drivers that support PERST# can clean
up things like eDMA (Manivannan Sadhasivam)
- Rename dw_pcie_ep_exit() to dw_pcie_ep_deinit() to make it parallel
to dw_pcie_ep_init() (Manivannan Sadhasivam)
- Rename dw_pcie_ep_init_complete() to dw_pcie_ep_init_registers() to
reflect the actual functionality (Manivannan Sadhasivam)
- Call dw_pcie_ep_init_registers() directly from all the glue
drivers, not just those that require active Refclk from the host
(Manivannan Sadhasivam)
- Remove the "core_init_notifier" flag, which was an obscure way for
glue drivers to indicate that they depend on Refclk from the host
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Add DT binding J784S4 SoC Device ID (Siddharth Vadapalli)

The IPR driver has a routine to check whether it's running on certain CPU
versions and if so whether the adapter is supported on that CPU.
But none of the CPUs it checks for are supported by Linux anymore.
The most recent CPU it checks for is Power4+ which was removed in commit
471d7ff8b51b ("powerpc/64s: Remove POWER4 support").
So drop the check. That makes the "testmode" module parameter unused, so
remove it as well.

These variables are not used, so remove them. The lock around res is not
needed so remove that. This makes ioa_cfg and lock_flags unneeded so remove
them as well.

Linux SATA support in ipr has always been limited to SATA DVDs. The last
systems that had the option of including a SATA DVD was Power 8, which have
been withdrawn for some time now, so this support can be removed.

The ipr_log_vpd_compact() function triggers a fortified memcpy() warning
about a potential string overflow with all versions of clang:
In file included from drivers/scsi/ipr.c:43:
In file included from include/linux/string.h:254:
include/linux/fortify-string.h:520:4: error: call to '__write_overflow_field' declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror,-Wattribute-warning]
__write_overflow_field(p_size_field, size);

include/linux/fortify-string.h:520:4: error: call to '__write_overflow_field' declared with 'warning' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror,-Wattribute-warning]
2 errors generated.
I don't see anything actually wrong with the function, but this is the only
instance I can reproduce of the fortification going wrong in the kernel at
the moment, so the easiest solution may be to rewrite the function into
something that does not trigger the warning.
Instead of having a combined buffer for vendor/device/serial strings, use
three separate local variables and just truncate the whitespace
individually.

The use of kmap() is deprecated in favor of kmap_local_page().
There are two main problems with kmap(): (1) It comes with an overhead as
the mapping space is restricted and protected by a global lock for
synchronization and (2) it also requires global TLB invalidation when the
kmap’s pool wraps and it might block when the mapping space is fully
utilized until a slot becomes available.
With kmap_local_page() the mappings are per thread, CPU local, can take
page faults, and can be called from any context (including interrupts). It
is faster than kmap() in kernels with HIGHMEM enabled. Furthermore, the
tasks can be preempted and, when they are scheduled to run again, the
kernel virtual addresses are restored and still valid.
Therefore, replace kmap() with kmap_local_page() in ipr_copy_ucode_buffer()
and, instead of open-coding local mappings + memcpy() + local un-mappings,
use the better suited memcpy_to_page() helper.

The name ATA_QCFLAG_FAILED is misleading since it does not mean that a
QC completed in error, or that it didn't complete at all. It means that
libata decided to schedule EH for the QC, so the QC is now owned by the
libata error handler (EH).
The normal execution path is responsible for not accessing a QC owned
by EH. libata core enforces the rule by returning NULL from
ata_qc_from_tag() for QCs owned by EH.
It is quite easy to mistake that a QC marked with ATA_QCFLAG_FAILED was
an error. However, a QC that was actually an error is instead indicated
by having qc->err_mask set. E.g. when we have a NCQ error, we abort all
QCs, which currently will mark all QCs as ATA_QCFLAG_FAILED. However, it
will only be a single QC that is an error (i.e. has qc->err_mask set).
Rename ATA_QCFLAG_FAILED to ATA_QCFLAG_EH to more clearly highlight that
this flag simply means that a QC is now owned by EH. This new name will
not mislead to think that the QC was an error (which is instead
indicated by having qc->err_mask set).
This also makes it more obvious that the EH code skips all QCs that do
not have ATA_QCFLAG_EH set (rather than ATA_QCFLAG_FAILED), since the EH
code should simply only care about QCs that are owned by EH itself.

Since snprintf() returns the would-be-output size instead of the actual
output size, the succeeding calls may go beyond the given buffer limit.
Fix it by replacing with scnprintf().

As a part of the scan process Linux will allocate and configure a
scsi_device for each target to be scanned. If the device is not present,
then the scsi_device is torn down. As a part of scsi_device teardown a
workqueue item will be scheduled and the lockups we see are because there
are 250k workqueue items to be processed. Accoding to the specification of
SIS-64 sas controller, max_channel should be decreased on SIS-64 adapters
to 4.
The patch fixes softlockup issue.
Thanks for Oliver Halloran's help with debugging and explanation!

The ata_sas_scsi_ioctl() function implements a number of HDIO_* commands
for SCSI devices, it is used by all libata drivers as well as a few
drivers that support SAS attached SATA drives.
The only command that is not safe for compat ioctls here is
HDIO_GET_32BIT. Change the implementation to check for in_compat_syscall()
in order to do both cases correctly, and change all callers to use it
as both native and compat callback pointers, including the indirect
callers through sas_ioctl and ata_scsi_ioctl.

Pull SCSI scatter-gather list updates from James Bottomley:
"This topic branch covers a fundamental change in how our sg lists are
allocated to make mq more efficient by reducing the size of the
preallocated sg list.
This necessitates a large number of driver changes because the
previous guarantee that if a driver specified SG_ALL as the size of
its scatter list, it would get a non-chained list and didn't need to
bother with scatterlist iterators is now broken and every driver
*must* use scatterlist iterators.
This was broken out as a separate topic because we need to convert all
the drivers before pulling the trigger and unconverted drivers kept
being found, necessitating a rebase"

Unlike the legacy I/O path, scsi-mq preallocates a large array to hold
the scatterlist for each request. This static allocation can consume
substantial amounts of memory on modern controllers which support a
large number of concurrently outstanding requests.
To facilitate a switch to a smaller static allocation combined with a
dynamic allocation for requests that need it, we need to make sure all
SCSI drivers handle chained scatterlists correctly.
Convert remaining drivers that directly dereference the scatterlist
array to using the iterator functions.
