This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

Pull pci updates from Bjorn Helgaas:
 "Enumeration:

   - Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that
     take config space accessor functions.

     Implement pci_find_capability(), pci_find_ext_capability(), and
     dwc, dwc endpoint, and cadence capability search interfaces with
     them (Hans Zhang)

   - Leave parent unit address 0 in 'interrupt-map' so that when we
     build devicetree nodes to describe PCI functions that contain
     multiple peripherals, we can build this property even when
     interrupt controllers lack 'reg' properties (Lorenzo Pieralisi)

   - Add a Xeon 6 quirk to disable Extended Tags and limit Max Read
     Request Size to 128B to avoid a performance issue (Ilpo Järvinen)

   - Add sysfs 'serial_number' file to expose the Device Serial Number
     (Matthew Wood)

   - Fix pci_acpi_preserve_config() memory leak (Nirmoy Das)

  Resource management:

   - Align m68k pcibios_enable_device() with other arches (Ilpo
     Järvinen)

   - Remove sparc pcibios_enable_device() implementations that don't do
     anything beyond what pci_enable_resources() does (Ilpo Järvinen)

   - Remove mips pcibios_enable_resources() and use
     pci_enable_resources() instead (Ilpo Järvinen)

   - Clean up bridge window sizing and assignment (Ilpo Järvinen),
     including:

       - Leave non-claimed bridge windows disabled

       - Enable bridges even if a window wasn't assigned because not all
         windows are required by downstream devices

       - Preserve bridge window type when releasing the resource, since
         the type is needed for reassignment

       - Consolidate selection of bridge windows into two new
         interfaces, pbus_select_window() and
         pbus_select_window_for_type(), so this is done consistently

       - Compute bridge window start and end earlier to avoid logging
         stale information

  MSI:

   - Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol
     Vives)

  Error handling:

   - Align AER with EEH by allowing drivers to request a Bus Reset on
     Non-Fatal Errors (in addition to the reset on Fatal Errors that we
     already do) (Lukas Wunner)

   - If error recovery fails, emit FAILED_RECOVERY uevents for the
     devices, not for the bridge leading to them.

     This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner)

   - Align AER with EEH by calling err_handler.error_detected()
     callbacks to notify drivers if error recovery fails (Lukas Wunner)

   - Align AER with EEH by restoring device error_state to
     pci_channel_io_normal before the err_handler.slot_reset() callback.

     This is earlier than before the err_handler.resume() callback
     (Lukas Wunner)

   - Emit a BEGIN_RECOVERY uevent when driver's
     err_handler.error_detected() requests a reset, as well as when it
     says recovery is complete or can be done without a reset (Niklas
     Schnelle)

   - Align s390 with AER and EEH by emitting uevents during error
     recovery (Niklas Schnelle)

   - Align EEH with AER and s390 by emitting BEGIN_RECOVERY,
     SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the
     result of err_handler.error_detected() (Niklas Schnelle)

   - Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES
     error information identifies a device without an AER Capability
     (Breno Leitao)

   - Update error decoding and TLP Log printing for new errors in
     current PCIe base spec (Lukas Wunner)

   - Update error recovery documentation to match the current code
     and use consistent nomenclature (Lukas Wunner)

  ASPM:

   - Enable all ClockPM and ASPM states for devicetree platforms, since
     there's typically no firmware that enables ASPM

     This is a risky change that may uncover hardware or configuration
     defects at boot-time rather than when users enable ASPM via sysfs
     later. Booting with "pcie_aspm=off" prevents this enabling
     (Manivannan Sadhasivam)

   - Remove the qcom code that enabled ASPM (Manivannan Sadhasivam)

  Power management:

   - If a device has already been disconnected, e.g., by a hotplug
     removal, don't bother trying to resume it to D0 when detaching the
     driver.

     This avoids annoying "Unable to change power state from D3cold to
     D0" messages (Mario Limonciello)

   - Ensure devices are powered up before config reads for
     'max_link_width', 'current_link_speed', 'current_link_width',
     'secondary_bus_number', and 'subordinate_bus_number' sysfs files.

     This prevents using invalid data (~0) in drivers or lspci and,
     depending on how the PCIe controller reports errors, may avoid
     error interrupts or crashes (Brian Norris)

  Virtualization:

   - Add rescan/remove locking when enabling/disabling SR-IOV, which
     avoids list corruption on s390, where disabling SR-IOV also
     generates hotplug events (Niklas Schnelle)

  Peer-to-peer DMA:

   - Free struct p2p_pgmap, not a member within it, in the
     pci_p2pdma_add_resource() error path (Sungho Kim)

  Endpoint framework:

   - Document sysfs interface for BAR assignment of vNTB endpoint
     functions (Jerome Brunet)

   - Fix array underflow in endpoint BAR test case (Dan Carpenter)

   - Skip endpoint IRQ test if the IRQ is out of range to avoid false
     errors (Christian Bruel)

   - Fix endpoint test case for controllers with fixed-size BARs smaller
     than requested by the test (Marek Vasut)

   - Restore inbound translation when disabling doorbell so the endpoint
     doorbell test case can be run more than once (Niklas Cassel)

   - Avoid a NULL pointer dereference when releasing DMA channels in
     endpoint DMA test case (Shin'ichiro Kawasaki)

   - Convert tegra194 interrupt number to MSI vector to fix endpoint
     Kselftest MSI_TEST test case (Niklas Cassel)

   - Reset tegra194 BARs when running in endpoint mode so the BAR tests
     don't overwrite the ATU settings in BAR4 (Niklas Cassel)

   - Handle errors in tegra194 BPMP transactions so we don't mistakenly
     skip future PERST# assertion (Vidya Sagar)

  AMD MDB PCIe controller driver:

   - Update DT binding example to separate PERST# to a Root Port stanza
     to make multiple Root Ports possible in the future (Sai Krishna
     Musham)

   - Add driver support for PERST# being described in a Root Port
     stanza, falling back to the host bridge if not found there (Sai
     Krishna Musham)

  Freescale i.MX6 PCIe controller driver:

   - Enable the 3.3V Vaux supply if available so devices can request
     wakeup with either Beacon or WAKE# (Richard Zhu)

  MediaTek PCIe Gen3 controller driver:

   - Add optional sys clock ready time setting to avoid sys_clk_rdy
     signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno)

   - Add DT binding and driver support for MT6991 and MT8196
     (AngeloGioacchino Del Regno)

  NVIDIA Tegra PCIe controller driver:

   - When asserting PERST#, disable the controller instead of mistakenly
     disabling the PLL twice (Nagarjuna Kristam)

   - Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock
     nesting error (Marek Vasut)

  Qualcomm PCIe controller driver:

   - Select PCI Power Control Slot driver so slot voltage rails can be
     turned on/off if described in Root Port devicetree node (Qiang Yu)

   - Parse only PCI bridge child nodes in devicetree, skipping unrelated
     nodes such as OPP (Operating Performance Points), which caused
     probe failures (Krishna Chaitanya Chundru)

   - Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang)

   - Consolidate Root Port 'phy' and 'reset' properties in struct
     qcom_pcie_port, regardless of whether we got them from the Root
     Port node or the host bridge node (Manivannan Sadhasivam)

   - Fetch and map the ELBI register space in the DWC core rather than
     in each driver individually (Krishna Chaitanya Chundru)

   - Enable ECAM mechanism in DWC core by setting up iATU with 'CFG
     Shift Feature' and use this in the qcom driver (Krishna Chaitanya
     Chundru)

   - Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya
     Chundru)

   - Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm
     Glymur, which is compatible with X1E80100 but doesn't have the
     cnoc_sf_axi clock (Qiang Yu)

  Renesas R-Car PCIe controller driver:

   - Fix a typo that prevented correct PHY initialization (Marek Vasut)

   - Add a missing 1ms delay after PWR reset assertion as required by
     the V4H manual (Marek Vasut)

   - Assure reset has completed before DBI access to avoid SError (Marek
     Vasut)

   - Fix inverted PHY initialization check, which sometimes led to
     timeouts and failure to start the controller (Marek Vasut)

   - Pass the correct IRQ domain to generic_handle_domain_irq() to fix a
     regression when converting to msi_create_parent_irq_domain()
     (Claudiu Beznea)

   - Drop the spinlock protecting the PMSR register - it's no longer
     required since pci_lock already serializes accesses (Marek Vasut)

   - Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock

  TI J721E PCIe driver:

   - Add MODULE_DEVICE_TABLE() so driver can be autoloaded (Siddharth
     Vadapalli)

     controller latches the correct values on power-on (Siddharth
     Vadapalli)

Under arch/sparc/ there are multiple copies of pcibios_enable_device() but
none of those seem to do anything extra beyond what pci_enable_resources()
is supposed to do. These functions could lead to inconsistencies in
behavior, especially now as pci_enable_resources() and the bridge window
resource flags behavior are going to be altered by upcoming changes.

Remove all pcibios_enable_device() from arch/sparc/ so that PCI core can

Most architectures turn on PCI_COMMAND_IO and PCI_COMMAND_MEMORY in
pci_enable_device() when a driver claims the device.  Sparc PCIC did it in
pcibios_fixup_bus(), which is called during enumeration, before any drivers
are attached.

Implement pcibios_enable_device() for PCIC so it will do the same as other
architectures.  This implementation is copied verbatim from sparc64.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

 - clean up by adding empty generic pcibios_align_resource() and
   pcibios_fixup_bus() and removing empty arch-specific implementations
   (Palmer Dabbelt)

 - request exclusive reset control for several drivers to allow cleanup
   elsewhere (Philipp Zabel)

 - constify various structures (Arvind Yadav, Bhumika Goyal)

 - convert from full_name() to %pOF (Rob Herring)

 - remove unused variables from iProc, HiSi, Altera, Keystone (Shawn
   Lin)

When building the kernel for Sparc using gcc 7.x, the build fails
with:

arch/sparc/kernel/pcic.c: In function ‘pcibios_fixup_bus’:
arch/sparc/kernel/pcic.c:647:8: error: ‘cmd’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
    cmd |= PCI_COMMAND_IO;
        ^~

The simplified code looks like this:

unsigned int cmd;
[...]
pcic_read_config(dev->bus, dev->devfn, PCI_COMMAND, 2, &cmd);
[...]
cmd |= PCI_COMMAND_IO;

I.e, the code assumes that pcic_read_config() will always initialize
cmd. But it's not the case. Looking at pcic_read_config(), if
bus->number is != 0 or if the size is not one of 1, 2 or 4, *val will
not be initialized.

As a simple fix, we initialize cmd to zero at the beginning of
pcibios_fixup_bus.
