792fb43ce2 iommu/vt-d: Enable Intel IOMMU scalable mode by default
The commit 8950dcd83ae7d ("iommu/vt-d: Leave scalable mode default off")
leaves the scalable mode default off and end users could turn it on with
"intel_iommu=sm_on". Using the Intel IOMMU scalable mode for kernel DMA,
user-level device access and Shared Virtual Address have been enabled.
This enables the scalable mode by default if the hardware advertises the
support and adds kernel options of "intel_iommu=sm_on/sm_off" for end
users to configure it through the kernel parameters.

d1f278da6b lkdtm: replace SCSI_DISPATCH_CMD with SCSI_QUEUE_RQ
When scsi_dispatch_cmd was moved to scsi_lib.c and made static, some
compilers (i.e., at least gcc 8.4.0) decided to compile this
inline. This is a problem for lkdtm.ko, which inserted a kprobe
on this function for the SCSI_DISPATCH_CMD crashpoint.

Move this crashpoint one function up the call chain to
scsi_queue_rq. Though this is also a static function, it should never be
inlined because it is assigned as a structure entry. Therefore,
kprobe_register should always be able to find it.

a083fadf54 dt-bindings: PCI: faraday,ftpci100: Fix 'contains' schema usage
The 'contains' keyword applies to elements within an array, so
using 'items' only makes sense if the elements of the array are another
array which is not the case for 'compatible' properties.

Looking at the driver, it seems the intent was the condition should be
true when 'faraday,ftpci100' is present, so we can drop
'cortina,gemini-pci'.

5c785014b6 Qualcomm driver updates for v5.15
This fixes the "shared memory state machine" (SMSM) interrupt logic to
 avoid missing transitions happening while the interrupts are masked.
 
 SM6115 support is added to smd-rpm and rpmpd.
 
 The Qualcomm SCM firmware driver is once again made possible to compile
 and load as a kernel module.
 
 An out-of-bounds error related to the cooling devices of the AOSS driver
 is corrected. The binding is converted to YAML and a generic compatible
 is introduced to reduce the driver churn.
 
 The GENI wrapper gains a helper function used in I2C and SPI for
 switching the serial engine hardware to use the wrapper's DMA-engine.
 
 Lastly it contains a number of cleanups and smaller fixes for rpmhpd,
 socinfo, CPR, mdt_loader and the GENI DT binding.

a0f480dc65 Qualcomm ARM64 updates for v5.15
SDM660 and SDM630 was concluded to be similar enough that they should be
 merged, and the derivative SDM636 was added to the bunch. The combined
 platform gained support for GPU, DMA, I2C, IMEM, display, power-domains,
 SDHCI, thermal, USB, interconnects, VADC, WLED and audio remoteproc. The
 Sony Xperia "Ganges" platform was similarly merged with "Nile", got
 cleaned up and gained touchscreen, USB, volume keys and uSD support.
 
 IPQ6018 gains USB2 and PCIe support and a few minor fixes. IPQ8074
 gains SCM, PRNG and Crypto support and a DT style update of the PCIe
 nodes.
 
 MSM8916 gains Coresight STM support. The Xiaomi Redmi 2 is introduced,
 with touchscreen, notification LED and IMU support. MSM8996 gains
 support for GPU cooling and v3.0 of the SoC, which is used to introduce
 support for the Sony Xperia X Performance, XZ and XZs phones.
 
 SC7180 finally gains DisplayPort support and LPASS is updated
 accordingly. A number of fixes are introduced and with the newly
 introduced DRM aux bus in place Trogdor's panel is moved under the eDP
 bridge. SC7280 gained USB, eMMC, SD-card, QFPROM and IPA support, the
 new IDP2 board was added.
 
 SM6126 (aka Snapdragon 665) was introduced, together with the Sony
 Xperia 10II phone with support for framebuffer, USB, eMMC and volume
 keys.
 
 SM8150 gained inline crypto support for UFS enabled, CPU opp-tables was
 introduced to scale DDR and L3 frequencies and SPI nodes where added, in
 addition to a number of smaller fixes.
 
 SM8250 gained a number of minor fixes and had its serial engines wired
 up to use the GENI wrappers' DMA engines.
 
 SM8350 had wakeup-parent defined for the TLMM gpio node and I2C13 was
 introduced.
 
 SDM845 display clocks was corrected and Lenovo Yoga C630 got IPA enabled
 and now has working LTE connectivity.
 
 Additionally a number of minor fixes throughout to correct DT validation
 warnings.
 
 Lastly v5.14-rc3 is merge in to resolve the merge conflicts caused by
 the USB maintainer deciding to fix a regression in his tree.

26225bea1d iommu: Expose DMA domain strictness via sysfs
The sysfs interface for default domain types exists primarily so users
can choose the performance/security tradeoff relevant to their own
workload. As such, the choice between the policies for DMA domains fits
perfectly as an additional point on that scale - downgrading a
particular device from a strict default to non-strict may be enough to
let it reach the desired level of performance, while still retaining
more peace of mind than with a wide-open identity domain. Now that we've
abstracted non-strict mode as a distinct type of DMA domain, allow it to
be chosen through the user interface as well.

9d9d90a9af 2nd set of new IIO device support and cleanups for the 5.15 cycle.
A small pull request to pick up a few new drivers and some cleanup
 and fix patches.
 
 New device support
 * ad5110 non-volatile digital potentiometer
   - New driver
 * renesas rzl/gl2 12-bit / 8 channel ADC block
   - New driver and bindings
 
 Minor or late breaking fixes and cleanups
 * ltc2983
   - Fix a false assumption of initial interrupt during probe().
 * hp03
   - Use devm_* to simplify probe and allow the remove function to be dropped.

b71759ef1e ovl: skip checking lower file's i_writecount on truncate
It is possible that a directory tree is shared between multiple overlay
instances as a lower layer.  In this case when one instance executes a file
residing on the lower layer, the other instance denies a truncate(2) call
on this file.

This only happens for truncate(2) and not for open(2) with the O_TRUNC
flag.

Fix this interference and inconsistency by removing the preliminary
i_writecount check before copy-up.

This means that unlike on normal filesystems truncate(argv[0]) will now
succeed.  If this ever causes a regression in a real world use case this
needs to be revisited.

One way to fix this properly would be to keep a correct i_writecount in the
overlay inode, but that is difficult due to memory mapping code only
dealing with the real file/inode.

4d314179d6 Qualcomm dts updates for v5.15
This introduces the MSM8226 platform and an initial dts for the Samsung
 Galaxy S III Neo phone.
 
 MSM8974 gains another UART and this is used to enable Bluetooth on the
 Sony Xperia Z2 Tablet. Samsung Galaxy S5 gains regulator definitions for
 audio and modem remoteprocs, effectively enabling these.
 
 DSI clocks on APQ8064 are updates as the old legacy clock names are no
 longer supported by the driver. And IPQ806x GMAC nodes gains AHB resets
 wired up.
 
 Lastly APQ8060 is converted to a SPDX header and the ethernet node is
 updates in accordance with the binding.

bb57164920 bpf: Reconfigure libbpf docs to remove unversioned API
This removes the libbpf_api.rst file from the kernel documentation.
The intention for this file was to pull documentation from comments
above API functions in libbpf. However, due to limitations of the
kernel documentation system, this API documentation could not be
versioned, which is counterintuative to how users expect to use it.
There is also currently no doc comments, making this a blank page.

Once the kernel comment documentation is actually contributed, it
will still exist in the kernel repository, just in the code itself.

A seperate site is being spun up to generate documentaiton from those
comments in a way in which it can be versioned properly.

This also reconfigures the bpf documentation index page to make it
easier to sync to the previously mentioned documentaiton site.
