sd_read_block_limits_ext() currently assumes that vpd->len excludes the
size of the page header. However, vpd->len describes the size of the entire
VPD page, therefore the sanity check is incorrect.
In practice this is not really a problem since we don't attach VPD
pages unless they actually report data trailing the header. But fix
the length check regardless.
This issue was identified by Wukong-Agent (formerly Tencent Woodpecker), a
code security AI agent, through static code analysis.

Add pm80xx_fatal_error_uevent_emit() which is called when the pm80xx
driver encouters a fatal error. The uevent has the following additional
custom key/value pair sets:
- DRIVER: driver name, pm80xx in this case
- HBA_NUM: the scsi host id of the device
- EVENT_TYPE: to indicate a fatal error
- REPORTED_BY: either driver or firmware
The uevent is anchored to the kernel object that represents the SCSI
controller, which includes other useful core variables, such as, ACTION,
DEVPATH, SUBSYSTEM, and more.
The fatal_error_uevent_emit() function is called when the controller
fatal error state changes. Since this doesn't happen often for a
specific SCSI host, there is no worries of a uevent storm.

With the ATA error model, an NCQ command failure always triggers an abort
(termination) of all NCQ commands queued on the device. In such case, the
SAT or the host must handle the failed command according to the command
sense data and immediately retry all other NCQ commands that were aborted
due to the failed NCQ command.
For SAS HBAs controlled by the mpt3sas driver, NCQ command aborts are not
handled by the HBA SAT and sent back to the host, with an ioc log
information equal to 0x31080000 (IOC_LOGINFO_PREFIX_PL with the PL code
PL_LOGINFO_CODE_SATA_NCQ_FAIL_ALL_CMDS_AFTR_ERR). The function
_scsih_io_done() always forces a retry of commands terminated with the
status MPI2_IOCSTATUS_SCSI_IOC_TERMINATED using the SCSI result
DID_SOFT_ERROR, regardless of the log_info for the command. This
correctly forces the retry of collateral NCQ abort commands, but with the
retry counter for the command being incremented. If a command to an ATA
device is subject to too many retries due to other NCQ commands failing
(e.g. read commands trying to access unreadable sectors), the collateral
NCQ abort commands may be terminated with an error as they run out of
retries. This violates the SAT specification and causes hard-to-debug
command errors.
Solve this issue by modifying the handling of the
MPI2_IOCSTATUS_SCSI_IOC_TERMINATED status to check if a command is for an
ATA device and if the command loginfo indicates an NCQ collateral
abort. If that is the case, force the command retry using the SCSI result
DID_IMM_RETRY to avoid incrementing the command retry count.

scsi_add_lun() tests the device vendor string of SCSI devices to detect
if a SCSI device is in fact an ATA device, in order to correctly handle
SATL power management. The function scsi_cdl_enable() also requires
knowing if a SCSI device is an ATA device to control the state of the
device CDL feature but this function does that by testing for the
presence of the VPD page 89h (ATA INFORMATION page).
sd_read_write_same() also has a similar test.
Simplify these different methods by adding the is_ata field to struct
scsi_device to remember that a SCSI device is in fact an ATA one based
on the device vendor name test. This field can also allow low level
SCSI host adapter drivers to take special actions for ATA devices
(e.g. to better handle ATA NCQ errors).
With this, simplify scsi_cdl_enable() and sd_read_write_same().

When a host is configured with a few LUNs and I/O is running, injecting
FC faults repeatedly leads to path recovery problems. The LUNs have 4
paths each and 3 of them come back active after say an FC fault which
makes 2 of the paths go down, instead of all 4. This happens after
several iterations of continuous FC faults.
Reason here is that we're returning an I/O error whenever we're
encountering sense code 06/04/0a (LOGICAL UNIT NOT ACCESSIBLE, ASYMMETRIC

In case a timeout happens and storvsc_channel_init() returns an error,

received (and processed) that skb, and there is a _really_ good chance
that all subsequent skbs for this sequence will be handled with the same
CPU. So we should just use the CPU on which this skb was allocated on and
save ourselves some overhead due to pointless scheduling.

Correct the error handling goto labels used when host lookup fails in
various flashnode-related event handlers:
- iscsi_new_flashnode()
- iscsi_del_flashnode()
- iscsi_login_flashnode()
- iscsi_logout_flashnode()
- iscsi_logout_flashnode_sid()
scsi_host_put() is not required when shost is NULL, so jumping to the
correct label avoids unnecessary operations. These functions previously
jumped to the wrong goto label (put_host), which did not match the
intended cleanup logic.
Use the correct exit labels (exit_new_fnode, exit_del_fnode, etc.) to
ensure proper error handling. Also remove the unused put_host label
under iscsi_new_flashnode() as it is no longer needed.
No functional changes beyond accurate error path correction.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Print the actual delay time in pci_bridge_wait_for_secondary_bus()
instead of assuming it was 1000ms (Wilfred Mallawa)
- Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
devices', which broke resume from system sleep on AMD platforms and
has been fixed by other commits (Lukas Wunner)
Resource management:
- Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
and unnecessary (Philipp Stanner)
- Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
and related flags since all uses have been removed (Philipp
Stanner)
- Rework devres 'request' functions so they are no longer 'hybrid',
i.e., their behavior no longer depends on whether
pcim_enable_device or pci_enable_device() was used, and remove
related code (Philipp Stanner)
- Warn (not BUG()) about failure to assign optional resources (Ilpo
Järvinen)
Error handling:
- Log the DPC Error Source ID only when it's actually valid (when
ERR_FATAL or ERR_NONFATAL was received from a downstream device)
and decode into bus/device/function (Bjorn Helgaas)
- Determine AER log level once and save it so all related messages
use the same level (Karolina Stolarek)
- Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
Errors (Karolina Stolarek)
- Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
controls on interval and burst count, to avoid flooding logs and
RCU stall warnings (Jon Pan-Doh)
Power management:
- Increment PM usage counter when probing reset methods so we don't
try to read config space of a powered-off device (Alex Williamson)
- Set all devices to D0 during enumeration to ensure ACPI opregion is
connected via _REG (Mario Limonciello)
Power control:
- Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
the filename paths. Retain old deprecated symbols for
compatibility, except for the pwrctrl slot driver
(PCI_PWRCTRL_SLOT) (Johan Hovold)
- When unregistering pwrctrl, cancel outstanding rescan work before
cleaning up data structures to avoid use-after-free issues (Brian
Norris)
Bandwidth control:
- Simplify link bandwidth controller by replacing the count of Link
Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
flag (Ilpo Järvinen)
- Update the Link Speed after retraining, since the Link Speed may
have changed (Ilpo Järvinen)
PCIe native device hotplug:
- Ignore Presence Detect Changed caused by DPC.
pciehp already ignores Link Down/Up events caused by DPC, but on
slots using in-band presence detect, DPC causes a spurious Presence
Detect Changed event (Lukas Wunner)
- Ignore Link Down/Up caused by Secondary Bus Reset.
On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)
Virtualization:
- Add an ACS quirk for Loongson Root Ports that don't advertise ACS
but don't allow peer-to-peer transactions between Root Ports; the
quirk allows each Root Port to be in a separate IOMMU group (Huacai
Chen)
Endpoint framework:
- For fixed-size BARs, retain both the actual size and the possibly
larger size allocated to accommodate iATU alignment requirements
(Jerome Brunet)
- Simplify ctrl/SPAD space allocation and avoid allocating more space
than needed (Jerome Brunet)
- Correct MSI-X PBA offset calculations for DesignWare and Cadence
endpoint controllers (Niklas Cassel)
- Align the return value (number of interrupts) encoding for
pci_epc_get_msi()/pci_epc_ops::get_msi() and
pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)
- Align the nr_irqs parameter encoding for
pci_epc_set_msi()/pci_epc_ops::set_msi() and
pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)
Common host controller library:
- Convert pci-host-common to a library so platforms that don't need
native host controller drivers don't need to include these helper
functions (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Extract ECAM bridge creation helper from pci_host_common_probe() to
separate driver-specific things like MSI from PCI things (Marc
Zyngier)
- Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
varying capabilities (Marc Zyngier)
- Skip ports disabled in DT when setting up ports (Janne Grunau)
- Add t6020 compatible string (Alyssa Rosenzweig)
- Add T602x PCIe support (Hector Martin)
- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)
- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)
- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)
- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)
Cadence PCIe controller driver:
- Drop a runtime PM 'put' to resolve a runtime atomic count underflow
(Hans Zhang)
- Make the cadence core buildable as a module (Kishon Vijay Abraham I)
- Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
loadable drivers when they are removed (Siddharth Vadapalli)
Freescale i.MX6 PCIe controller driver:
- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)
- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)
- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)
- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)
- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)
- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)
- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)
Mobiveil PCIe controller driver:
- Return bool (not int) for link-up check in
mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
Zhang)
NVIDIA Tegra194 PCIe controller driver:
- Create debugfs directory for 'aspm_state_cnt' only when
CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
Zhang)
Qualcomm PCIe controller driver:
- Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
equalization presets (Krishna Chaitanya Chundru)
- Read Maximum Link Width from the Link Capabilities register if DT
lacks 'num-lanes' property (Krishna Chaitanya Chundru)
- Add Physical Layer 64 GT/s Capability ID and register offsets for
8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
Chundru)
- Add generic dwc support for configuring lane equalization presets
(Krishna Chaitanya Chundru)
- Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)
Renesas R-Car PCIe controller driver:
- Describe endpoint BAR 4 as being fixed size (Jerome Brunet)
- Document how to obtain R-Car V4H (r8a779g0) controller firmware
(Yoshihiro Shimoda)
Rockchip PCIe controller driver:
- Reorder rockchip_pci_core_rsts because
reset_control_bulk_deassert() deasserts in reverse order, to fix a
link training regression (Jensen Huang)
- Mark RK3399 as being capable of raising INTx interrupts (Niklas
Cassel)
Rockchip DesignWare PCIe controller driver:
- Check only PCIE_LINKUP, not LTSSM status, to determine whether the
link is up (Shawn Lin)
- Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
for Root Complex and Endpoint modes (Shawn Lin)
- Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
resets non-sticky registers (Shawn Lin)
- Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
(Diederik de Haas)
Synopsys DesignWare PCIe controller driver:
- Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
more robust; this will not affect the intended link width if all
lanes are functional (Wenbin Yao)
- Return bool (not int) for link-up check in dw_pcie_ops.link_up()
and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
tegra194, uniphier, visconti (Hans Zhang)
- Add debugfs support for exposing DWC device-specific PTM context
(Manivannan Sadhasivam)
TI J721E PCIe driver:
- Make j721e buildable as a loadable and removable module (Siddharth
Vadapalli)
- Fix j721e host/endpoint dependencies that result in link failures
in some configs (Arnd Bergmann)
Device tree bindings:
- Add qcom DT binding for 'global' interrupt (PCIe controller and
link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p,
sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan
Sadhasivam)
- Add qcom DT binding for 8 MSI SPI interrupts for msm8998, ipq8074,
ipq8074-gen3, ipq6018 (Manivannan Sadhasivam)
- Add dw rockchip DT binding for rk3576 and rk3562 (Kever Yang)
- Correct indentation and style of examples in brcm,stb-pcie,
cdns,cdns-pcie-ep, intel,keembay-pcie-ep, intel,keembay-pcie,
microchip,pcie-host, rcar-pci-ep, rcar-pci-host, xilinx-versal-cpm
(Krzysztof Kozlowski)

and IPQ9574 (Varadarajan Narayanan)
- Convert v3,v360epc-pci from text to DT schema binding (Rob Herring)
- Change microchip,pcie-host DT binding to be 'dma-noncoherent' since
PolarFire may be configured that way (Conor Dooley)
Miscellaneous:
- Drop 'pci' suffix from intel_mid_pci.c filename to match similar
files (Andy Shevchenko)
- All platforms with PCI have an MMU, so add PCI Kconfig dependency
on MMU to simplify build testing and avoid inadvertent build
regressions (Arnd Bergmann)

The REPORT ZONES buffer size is currently limited by the HBA's maximum
segment count to ensure the buffer can be mapped. However, the block
layer further limits the number of iovec entries to 1024 when allocating
a bio.
To avoid allocation of buffers too large to be mapped, further restrict
the maximum buffer size to BIO_MAX_INLINE_VECS.
Replace the UIO_MAXIOV symbolic name with the more contextually
appropriate BIO_MAX_INLINE_VECS.

scsi: ufs: core: Remove redundant query_complete trace
scsi: myrb: Fix spelling mistake "statux" -> "status"
Don Brace <don.brace@microchip.com> says:
These patches are based on Martin Petersen's 6.16/scsi-queue tree
https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git
6.16/scsi-queue
There are two main functional changes in this patch series:
smartpqi-take-drives-offline-when-controller-is-offline
smartpqi-fix-smp_processor_id-call-trace-for-preemptible-kernels
The other two patches add PCI-IDs for new controllers and change the
driver version.
This set of changes consists of:
* smartpqi-take-drives-offline-when-controller-is-offline
On rare occasions, the controller can lock up and the driver was
removing the controller instance from OS but leaving the
drives exposed and their state was still 'running'.
This patch sets the drive state as 'offline' to avoid confusion.
* smartpqi-add-new-pci_ids
Add support for more PCI devices.
* smartpqi-enhance_wwid-logging-logic
Cosmetic change for logging WWIDs for NVMe devices and for drives
that support the extended format.
* smartpqi-fix-smp_processor_id-call-trace-for-preemptible-kernels
When preemption is enabled, there are call traces in the console
logs which are annoying. The call trace mentions using
smp_processor_id(). Since the driver is only using this function call
when accessing a per_cpu variable, we changed the call to
raw_smp_processor_id(). This patch was written by
Yi Zhang <yi.zhang@redhat.com> and I am posting it on his behalf.
* smartpqi-update-driver-version-to-2.1.34-035
No functional changes.

A PCI function reset implies a temporary disappearance of a fc_rport.
So, call lpfc_scsi_dev_block(), which sets all mapped fc_rports into the
temporary FC_PORTSTATE_BLOCKED state. Once PCI function reset completes
and link reinitialized, the fc_rport is rediscovered and
FC_PORTSTATE_BLOCKED state is removed.

In lpfc_check_sli_ndlp(), the get_job_els_rsp64_did remote_id assignment
does not apply for GEN_REQUEST64 commands as it only has meaning for a
ELS_REQUEST64 command. So, if (iocb->ndlp == ndlp) is false, we could
erroneously return the wrong value. Fix by replacing the fallthrough
statement with a break statement before the remote_id check.

In preparation for making the kmalloc family of allocators type aware, we
need to make sure that the returned type from the allocation matches the
type of the variable being assigned. (Before, the allocator would always
return "void *", which can be implicitly cast to any pointer type.)
The assigned type is "struct crb_addr_pair *" and the returned type will
be a _different_ "struct crb_addr_pair *", causing a warning. This really
stumped me for a bit. :) Drop the redundant declaration.

It turns out that there are no platforms that have PCI but don't have an
MMU, so adding a Kconfig dependency on CONFIG_PCI simplifies build testing
kernels for those platforms a lot, and avoids a lot of inadvertent build
regressions.
Add a dependency for CONFIG_PCI and remove all the ones for PCI specific
device drivers that are currently marked not having it.
There are a few platforms that have an optional MMU, but they usually
cannot have PCI at all. The one exception is Coldfire MCF54xx, but this is
mainly for historic reasons, and anyone using those chips should really use
the MMU these days.

With ATA devices supporting the CDL feature, using CDL requires that the
feature be enabled with a SET FEATURES command. This command is issued
as the translated command for the MODE SELECT command issued by
scsi_cdl_enable() when the user enables CDL through the device
cdl_enable sysfs attribute.
However, the implementation of scsi_cdl_enable() always issues a MODE
SELECT command for ATA devices when the enable argument is true, even if
CDL is already enabled on the device. While this does not cause any
issue with using CDL descriptors with read/write commands (the CDL
feature will be enabled on the drive), issuing the MODE SELECT command
even when the device CDL feature is already enabled will cause a reset
of the ATA device CDL statistics log page (as defined in ACS, any CDL
enable action must reset the device statistics).
Avoid this needless actions (and the implied statistics log page reset)
by modifying scsi_cdl_enable() to issue the MODE SELECT command to
enable CDL if and only if CDL is not reported as already enabled on the
device.
And while at it, simplify the initialization of the is_ata boolean
variable and move the declaration of the scsi mode data and sense header
variables to within the scope of ATA device handling.

Hi,
This is a batch of deadcoding on the qla2xxx driver.
Note the last patch removes two unused module
parameters, so I guess if anyone has that in some configs
somewhere that might surprise them.
Other than that, it's all simple function deletion.
