NCQ priority is an optional feature of the NCQ feature set and should
not be confused with the NCQ feature set itself. Clarify the
description of the ncq_prio_enable attribute to avoid this confusion.
Also add the missing documentation for the equivalent
sas_ncq_prio_enable attribute.

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.

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.

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.

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.

Turn BPF_PROG_RUN into a proper always inlined function. No functional and
performance changes are intended, but it makes it much easier to understand
what's going on with how BPF programs are actually get executed. It's more
obvious what types and callbacks are expected. Also extra () around input
parameters can be dropped, as well as `__` variable prefixes intended to avoid
naming collisions, which makes the code simpler to read and write.
This refactoring also highlighted one extra issue. BPF_PROG_RUN is both
a macro and an enum value (BPF_PROG_RUN == BPF_PROG_TEST_RUN). Turning
BPF_PROG_RUN into a function causes naming conflict compilation error. So
rename BPF_PROG_RUN into lower-case bpf_prog_run(), similar to
bpf_prog_run_xdp(), bpf_prog_run_pin_on_cpu(), etc. All existing callers of
BPF_PROG_RUN, the macro, are switched to bpf_prog_run() explicitly.

While users can restrict the accepted hash algorithms for the
security.ima xattr file signature when appraising said file, users
cannot restrict the algorithms that can be set on that attribute:
any algorithm built in the kernel is accepted on a write.
Define a new value for the ima policy option 'func' that restricts
globally the hash algorithms accepted when writing the security.ima
xattr.
When a policy contains a rule of the form
appraise func=SETXATTR_CHECK appraise_algos=sha256,sha384,sha512
only values corresponding to one of these three digest algorithms
will be accepted for writing the security.ima xattr. Attempting to
write the attribute using another algorithm (or "free-form" data)
will be denied with an audit log message. In the absence of such a
policy rule, the default is still to only accept hash algorithms
built in the kernel (with all the limitations that entails).

The kernel has the ability to restrict the set of hash algorithms it
accepts for the security.ima xattr when it appraises files.
Define a new IMA policy rule option "appraise_algos=", using the
mentioned mechanism to expose a user-toggable policy knob to opt-in
to that restriction and select the desired set of algorithms that
must be accepted.
When a policy rule uses the 'appraise_algos' option, appraisal of a
file referenced by that rule will now fail if the digest algorithm
employed to hash the file was not one of those explicitly listed in
the option. In its absence, any hash algorithm compiled in the
kernel will be accepted.
For example, on a system where SELinux is properly deployed, the rule
appraise func=BPRM_CHECK obj_type=iptables_exec_t \
appraise_algos=sha256,sha384
will block the execution of iptables if the xattr security.ima of its
executables were not hashed with either sha256 or sha384.

Drivers like thinkpad_acpi and ideapad_laptop call the
platform_profile_notify() helper when the profile is changed by hardware
(the embedded-controller/EC) in response to an EC handled hotkey.
This allows userspace to monitor for such changes by polling for POLLPRI
on the platform_profile sysfs file. But the profile can also be changed
underneath a userspace program monitoring it by anonther userspace program
storing a new value.
Add a sysfs_notify() call to platform_profile_store(), so that userspace
programs monitoring for changes also get notified in this case.
Also update the documentation to document that POLLPRI polling can be
used to watch for changes.
