  upstream 79c168e2aa95 ("PCI/AER: Skip error recovery on false alarms")
  vs PCI   d4c842c3af5b ("PCI/AER: Fix memory leak in aer_recover_work_func() when pci_dev is missing")

Preferred resolution at https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git/tree/drivers/pci/pcie/aer.c?h=v7.4-merge#n1395

----------------------------------------------------------------

Enumeration:

  - Set supported_speeds in set_pcie_port_type() so sparc64 and powerpc,
    which call it via of_create_pci_dev() instead of the usual
    pci_setup_device(), correctly set the supported PCIe link speeds (Stian
    Halseth)

  - When pcie_set_mps() changes MPS, update the value in the saved state so
    a subsequent restore doesn't restore an invalid value (Niklas Cassel)

  - Skip Target Speed quirk on clamped ports with no link (Maciej W.
    Rozycki)

Driver binding:

  - Assume control of portdrv-related features only when portdrv is
    enabled, since we can't use them without portdrv (Kuppuswamy
    Sathyanarayanan)

  - Centralize feature ownership checking so code only needs to check
    'host->native_X' and doesn't need to also check 'pcie_ports_native'
    (Kuppuswamy Sathyanarayanan)

Error handling:

  - Fix leaks when ACPI APEI/GHES error events overflow the kfifo or
    mention a device that no longer exists (Priyank Rathod)

  - Fix aer_process_err_devices() leak when a device is recorded as an
    error source purely by being mentioned in the Root Port Error Source
    and the device is inaccessible or logged only masked errors (Priyank
    Rathod)

ASPM:

  - Disable ASPM when drivers request that, even if the OS doesn't own
    ASPM; otherwise drivers do it on their own, which is worse (Ilpo
    Järvinen)

Power management:

  - Align hibernate poweroff flow with suspend flow for bridges so they can
    be powered down at hibernate as they are for suspend (Mario
    Limonciello)

  - Restore BARs after powering up during enumeration to fix a regression
    on devices that don't preserve state in D3hot (Keng-Yu Lin)

  - Avoid D3 on PLX PEX 8532/8533/8548 downstream ports, where putting them
    in D3hot takes down the whole switch (Imre Kaloz)

Power control:

  - Add GPIO driver for Toshiba TC9563 embedded GPIO controller (Alex
    Elder)

  - Add DT documentation and pwrctrl driver support for TC9563 embedded
    GPIO controller (Lorenzo Bianconi)

  - Switch the tc9563 per-port reset to use the GPIO descriptor API instead
    of direct regmap accesses (Lorenzo Bianconi)

  - Only destroy devices created by pwrctrl core, so that when removing a
    PCIe controller driver that uses pwrctrl, we don't remove devices
    populated by another mechanism (Shawn Lin)

  - Power off child devices on power-on failure (Lorenzo Bianconi)

PCIe native device hotplug:

  - Make the 'pciehp_poll_mode' parameter read-only to prevent changes via
    sysfs, which can cause errors when unbinding (Runyu Xiao)

Virtualization:

  - Read SR-IOV VF Revision ID and Subsystem ID from VF instead of assuming
    they're the same as VF 0; they may differ (Logan Odell)

  - Add ACS quirk for Pericom PI7C9X2G304 switches (Hans de Goede)

Peer-to-peer DMA:

  - Add Zhaoxin KX-6000, KH-40000, KX-6000G, KX-7000, and KH-50000 host
    bridges to allowlist (LeoLiu-oc)

  - Add Alibaba T-HEAD Yitian 710 host bridge to allowlist (Feng Tang)

  - Add Intel Haswell client host bridge to allowlist (Scott Lee)

  - Intel Xeon E3/E5/E7 0x6f00 host bridge to allowlist (kai zhang)

  - Fix handling of errors in pci_p2pdma_add_resource() to avoid (a)
    unmapping a BAR if registering another fails and (b) use after free of
    p2p_pgmap (Leon Romanovsky)

  - Wait for RCU readers before freeing state to avoid use-after-free of
    pdev->p2pdma (Leon Romanovsky)

  - Restrict pci_p2pmem_find_many() to providers backed by a pool (Leon
    Romanovsky)

  - Safely terminate ACS redirect lists to avoid out-of-bounds access to
    the buffer (Leon Romanovsky)

  - Silence 'Host bridge not in P2PDMA whitelist' warnings unless caller,
    e.g., pci_p2pmem_find_many(), requests 'verbose' (Leon Romanovsky)

Sysfs:

  - Return -ENODEV or -EIO sysfs 'label' or 'acpi_index' attributes when
    Device Name _DSM fails, not -1, which is interpreted as -EPERM
    (Krzysztof Wilczyński)

  - Return valid sysfs 'acpi_index' attribute even if the Device Name _DSM
    returned an invalid 'label' (Krzysztof Wilczyński)

  - Expose sysfs 'acpi_index' and 'label' based on whether the Device Name
    _DSM returns valid data, not merely whether the _DSM is implemented
    (Krzysztof Wilczyński)

  - Avoid out-of-bounds reads of the label returned by the Device Name
    _DSM, which is in UTF-16 characters, not bytes (Krzysztof Wilczyński)

  - Reject unaligned resource I/O port accesses, which can oops on arm64
    (Deepanshu Kartikey)

Endpoint framework:

  - Pass the correct physical and virtual endpoint function numbers when
    setting translation of inbound memory windows (Koichiro Den)

  - Make embedded doorbell IRQ non-shared, since currently only the first
    EPF can allocate doorbells (Koichiro Den)

  - MSI doorbells currently target the first EPF attached to an EPC; let
    other EPFs try the embedded doorbell instead of failing when they can't
    use the MSI doorbell (Koichiro Den)

  - Serialize scan of vNTB virtual PCI bus with other PCI topology changes
    (Koichiro Den)

  - Manage vNTB lifetimes to avoid leaking virtual devices and buses and
    allow removal (Koichiro Den)

  - Track vNTB link state from both sides so both see the same effective
    link state (Koichiro Den)

  - Configure vNTB MSI-X when supported to avoid IOMMU faults and failure
    to deliver doorbell interrupts on RC (Koichiro Den)

APM X-Gene PCIe controller driver:

  - Use devm for clocks so they're automatically disabled, unprepared, and
    released if errors happen during probe (Yuho Choi)

ASPEED PCIe controller driver:

  - Fix clk and PHY leaks in aspeed_pcie_port_init() error paths (Liu
    Zhenlong)

Broadcom iProc PCIe controller driver:

  - Expose devm_pci_alloc_host_bridge_release() so drivers can share a devm
    release function even if they don't need the device tree parsing done
    by devm_pci_alloc_host_bridge() (Bjorn Helgaas)

  - Request only the memory window from BCMA Enumeration ROM and warn if it
    doesn't match the one in DT, which fixes an iproc-bcma probe failure
    (Semih Baskan)

Broadcom STB PCIe controller driver:

  - Replace bool properties for each SoC configuration with a u32 bitvector
    and a BFLAG() helper (Jim Quinlan)

  - Use a similar BQUIRK() helper to test various SoC quirks (Jim Quinlan)

Cadence PCIe controller driver:

  - Remove device links to PHY, which are redundant because the PHY core
    itself adds them (Vladimir Oltean)

  - Return error (not success) from cdns_plat_pcie_probe() if
    pm_runtime_get_sync() or cdns_pcie_ep_setup() failed (Vladimir Oltean)

  - Correct the driver data pointer usage; previously .probe() stored
    'struct cdns_plat_pcie *', but .shutdown() used the pointer as 'struct
    cdns_pcie *', resulting in accessing garbage  (Linmao Li)

ESWIN PCIe controller driver:

  - Publish the platform driver MODULE_DEVICE_TABLE so the driver can be
    autoloaded when built as a module (Pengpeng Hou)

Freescale i.MX6 PCIe controller driver:

  - Fix resource and pwrctrl device leaks .probe() (Zhijian Han)

  - Improve i.MX95 Gen3 link stability by changing MPLLB_BANDWIDTH from
    default 120 to 140 (Richard Zhu)

  - Use dev_err_probe() in host init error path to silence -EPROBE_DEFER
    messages (Alexander Stein)

  - Avoid dereferencing NULL clock names when 'clocks' includes more
    phandles than 'clock-names' has names (Rudi Heitbaum)

  - Add suspend_poweroff flag so platforms like i.MX that power off RC
    controllers during suspend can enter L2 so endpoints can get
    PME_Turn_Off notifications before power loss (Richard Zhu)

Freescale Layerscape PCIe controller driver:

  - Enable PROBE_PREFER_ASYNCHRONOUS to reduce probe time of the four
    controllers on LX2160A (Vincent Jardin)

Intel VMD host bridge driver:

  - Flush DMA writes before handling MSI on Meteor Lake: MSI may arrive
    before write has completed, resulting in an nvme 30 second stall before
    a QID timeout and possibly other similar problems (Rickey Bartlett)

  - Flush DMA writes before handling MSI on Arrow Lake (Vladimir
    Nedoshivin)

Marvell Aardvark PCIe controller driver:

  - Refcount child OF nodes during .probe() to make a concurrent OF overlay
    removal safe (Krzysztof Kozlowski)

    issues with windows above or larger than 4GB (Sreeraj S Kurup)

NVIDIA Tegra264 PCIe controller driver:

  - Fix the Link Capabilities offset so we read the correct register (Bjorn
    Helgaas)

Qualcomm PCIe controller driver:

  - Only collect reset GPIOs from PCI bridge DT nodes to avoid stealing
    resets used by downstream devices like USB controllers (Christopher
    Obbard)

  - Block accesses to downstream devices on link down to reduce a storm of
    Completion Timeout AER interrupts (Qiang Yu)

  - Skip system suspend/resume for firmware-managed PCIe, where firmware
    manages clocks, regulators, resets, etc (Mrinmay Sarkar)

  - Honor IOMMU provider's #iommu-cells in qcom_pcie_config_sid_1_9_0()
    (Manivannan Sadhasivam)

  - Deinitialize endpoint on remove (Guangshuo Li)

  - Treat Root Port error recovery as successful even if link doesn't come
    up after reset because the device was hot-unplugged (Konrad Dybcio)

  - Skip unnecessary iMSI-RX initialization if DT 'msi-map' is present,
    indicating an external MSI controller (Ayiluri Naga Rashmi)

Renesas R-Car PCIe controller driver:

  - Limit Max_Read_Request_Size to 256 to avoid hardware erratum (Marek
    Vasut)

  - Support PERST# via reset subsystem as well as the existing GPIO support
    to prepare for R-Car Gen5 SoCs (Marek Vasut)

    correctly (Lad Prabhakar)

  - Tear down INTx handlers if subsequent initialization fails (Lad
    Prabhakar)

  - Add RZ/G3L (R9A08G046) DT and driver support (Biju Das)

Rockchip PCIe controller driver:

  - Limit host and endpoint controllers to 2.5 GT/s since 5.0 GT/s is
    unsafe per Rockchip (Geraldo Nascimento)

Synopsys DesignWare PCIe controller driver:

  - Set DMA_BYPASS bit in outbound IATU CTRL2 register to avoid data
    corruption if the iATU translates DMA engine transactions (Sumit Kumar)

  - Use FIELD_PREP() to remove need for *_SHIFT definitions (Hans Zhang)

TI DRA7xx PCIe controller driver:

  - Remove device links to PHY, which are redundant because the PHY core
    itself adds them (Vladimir Oltean)

  - Fix optional clock leak when .probe() fails by using
