Removing a PCI devices requires holding pci_rescan_remove_lock. Prompted by
this being missed in sriov_disable() and going unnoticed since its
inception, add a lockdep assert so this doesn't get missed again in the
future.

Before disabling SR-IOV via config space accesses to the parent PF,
sriov_disable() first removes the PCI devices representing the VFs.
Since commit 9d16947b7583 ("PCI: Add global pci_lock_rescan_remove()")
such removal operations are serialized against concurrent remove and
rescan using the pci_rescan_remove_lock. No such locking was ever added
in sriov_disable() however. In particular when commit 18f9e9d150fc
("PCI/IOV: Factor out sriov_add_vfs()") factored out the PCI device
removal into sriov_del_vfs() there was still no locking around the
pci_iov_remove_virtfn() calls.
On s390 the lack of serialization in sriov_disable() may cause double
remove and list corruption with the below (amended) trace being observed:
PSW: 0704c00180000000 0000000c914e4b38 (klist_put+56)
GPRS: 000003800313fb48 0000000000000000 0000000100000001 0000000000000001

This is because in addition to sriov_disable() removing the VFs, the
platform also generates hot-unplug events for the VFs. This being the
reverse operation to the hotplug events generated by sriov_enable() and
handled via pdev->no_vf_scan. And while the event processing takes
pci_rescan_remove_lock and checks whether the struct pci_dev still exists,
the lack of synchronization makes this checking racy.
Other races may also be possible of course though given that this lack of
locking persisted so long observable races seem very rare. Even on s390 the
list corruption was only observed with certain devices since the platform
events are only triggered by config accesses after the removal, so as long
as the removal finished synchronously they would not race. Either way the
locking is missing so fix this by adding it to the sriov_del_vfs() helper.
Just like PCI rescan-remove, locking is also missing in sriov_add_vfs()
including for the error case where pci_stop_and_remove_bus_device() is
called without the PCI rescan-remove lock being held. Even in the non-error
case, adding new PCI devices and buses should be serialized via the PCI
rescan-remove lock. Add the necessary locking.

The admin queue work request buffer, aq->q_wr, is allocated via kcalloc in
__ionic_create_rdma_adminq. However, it was not being freed in the
corresponding teardown function __ionic_destroy_rdma_adminq. This results
in a memory leak. Fix this leak by adding the missing kfree(aq->q_wr) in
the destruction path.

In siw_post_send(), any immediate error encountered during processing of
the work request list must be reported to the caller, even if previous
work requests in that list were just accepted and added to the send queue.
Not reporting those errors confuses the caller, which would wait
indefinitely for the failing and potentially subsequently aborted work
requests completion.
This fixes a case where immediate errors were overwritten by subsequent
code in siw_post_send().

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize on
the __ASSEMBLER__ macro that is provided by the compilers now.
This is a completely mechanical patch (done with a simple "sed -i"
statement).

PCI devices prior to PCI 2.3 both use level interrupts and do not support
interrupt masking, leading to a failure when passed through to a KVM guest on
at least the ppc64 platform. This failure manifests as receiving and
acknowledging a single interrupt in the guest, while the device continues to
assert the level interrupt indicating a need for further servicing.
When lazy IRQ masking is used on DisINTx- (non-PCI 2.3) hardware, the following
sequence occurs:
* Level IRQ assertion on device
* IRQ marked disabled in kernel
* Host interrupt handler exits without clearing the interrupt on the device
* Eventfd is delivered to userspace
* Guest processes IRQ and clears device interrupt
* Device de-asserts INTx, then re-asserts INTx while the interrupt is masked
* Newly asserted interrupt acknowledged by kernel VMM without being handled
* Software mask removed by VFIO driver
* Device INTx still asserted, host controller does not see new edge after EOI
The behavior is now platform-dependent. Some platforms (amd64) will continue
to spew IRQs for as long as the INTX line remains asserted, therefore the IRQ
will be handled by the host as soon as the mask is dropped. Others (ppc64) will
only send the one request, and if it is not handled no further interrupts will
be sent. The former behavior theoretically leaves the system vulnerable to
interrupt storm, and the latter will result in the device stalling after
receiving exactly one interrupt in the guest.
Work around this by disabling lazy IRQ masking for DisINTx- INTx devices.

In xe_hw_engine_group_get_mode(), a write lock is acquired before
calling switch_mode(), which in turn invokes
xe_hw_engine_group_suspend_faulting_lr_jobs().
On failure inside xe_hw_engine_group_suspend_faulting_lr_jobs(),
the write lock is released there, and then again in
xe_hw_engine_group_get_mode(), leading to a double release.
Fix this by keeping both acquire and release operation in
xe_hw_engine_group_get_mode().

The devm_auxiliary_device_create() returns NULL on error. It never
returns error pointers. Using PTR_ERR_OR_ZERO() here means the function
always returns success. Replace the PTR_ERR_OR_ZERO() call check with
a NULL check.

Convert the PC Engines APUv2/v3 board driver to use software nodes
and static device properties for its on-board LEDs and front button.
This change replaces the legacy gpiod_lookup_table and platform_data
with a modern software node implementation, which allows the leds-gpio
and gpio-keys drivers to use the standard device properties API.

2 fixes for Lenovo tablets:
- The bq24190 charger on the Lenovo Yoga Tab2 830/1050 devices does not use
the crystal-cove PMIC charger IRQ, so these shouldn't use bq24190_modules
as that includes "intel_crystal_cove_charger"
- Both the Tab2 and the Tab3 devices have a SPI audio-codec which init()
attaches properties to, resp. the whole SPI device gets instantiated by
the x86-android-tablets code. This requires the "spi_pxa2xx_platform"
module to be loaded before init() runs

Add support for the Acer Iconia One 8 A1-840 (non FHD version) tablet.
This tablet has the usual issues for tablets shipped with Android as
factory OS. The DSDT is broken in various ways, so i2c_clients for
various devices as well as the INT3496 platform-device for OTG extcon
handling need to be instantiated manually by x86-android-tablets.
This tablet is special in that it is the first time a Bay Trail device
has been found to use the Dollar Cove TI PMIC and the first time that
the PMIC's Coulomb Counter is used as fuel-gauge.
So far this PMIC has only been used together with Cherry Trail SoCs
and always in combination with a separate full-featured fuel-gauge IC.

Acer has several x86 based Android tablets which need x86-android-tablets
support to work around their broken ACPI tables.
At the moment x86-android-tablets only support one model, move this to
its own file before adding support for more models to avoid needing to
move more code around later.

software_node_register_node_group() / software_node_unregister_node_group()
both accept a NULL node-group as argument.
So there is no need to check for the node-group being NULL before calling
these functions, remove the checks to simplify the code.
Note the "if (gpio_button_swnodes)" check for registering is kept because
that also guards the creation of a gpio-button platform-device.

Now that gpiolib supports software nodes to describe GPIOs, switch the
driver away from using GPIO lookup tables for Goodix touchscreens to
using PROPERTY_ENTRY_GPIO() to keep all touchscreen properties together.
Since the tablets are using either Baytrail or Cherryview GPIO
controllers x86_dev_info structure has been extended to carry gpiochip
type information so that the code can instantiate correct set of
software nodes representing the GPIO chip.
Because this adds a new point of failure in x86_android_tablet_probe(),
x86_android_tablet_remove() is rearranged to handle cases where battery
swnode has not been registered yet, and registering of GPIO lookup
tables is moved earlier as it can not fail.

Introduce EC driver for the ThinkPad T14s Gen6 Snapdragon, which is in
theory compatible with ThinkPad ACPI. On Linux the system is booted with
device tree, which is not supported by the ThinkPad ACPI driver
(drivers/platform/x86/lenovo/thinkpad_acpi.c). Also most of the hardware
compatibility is handled via ACPI tables, which are obviously not used
when booting via device tree. Thus adding DT compatibility to the
existing driver is not worth it as there is almost no code sharing.
The driver currently exposes features, which are not available
via other means:
* Extra Keys
* System LEDs
* Keyboard Backlight Control
The driver has been developed by reading the ACPI DSDT. There
are some more features around thermal control, which are not
yet supported by the driver.
The speaker mute and mic mute LEDs need some additional changes
in the ALSA UCM to be set automatically.

mpfs_gpio_direction_output() actually sets the line to input mode.
Use the correct register settings for output mode so that this function
actually works as intended.
This was a copy-paste mistake made when converting to regmap during the
driver submission process. It went unnoticed because my test for output
mode is toggling LEDs on an Icicle kit which functions with the
incorrect code. The internal reporter has yet to test the patch, but on
their system the incorrect setting may be the reason for failures to
drive the GPIO lines on the BeagleV-fire board.
