This kselftest update for Linux 5.5-rc1 adds KUnit, a lightweight unit
testing and mocking framework for the Linux kernel from Brendan Higgins.
KUnit is not an end-to-end testing framework. It is currently supported
on UML and sub-systems can write unit tests and run them in UML env.
KUnit documentation is included in this update.
In addition, this Kunit update adds 3 new kunit tests:
- kunit test for proc sysctl from Iurii Zaikin
- kunit test for the 'list' doubly linked list from David Gow
- ext4 kunit test for decoding extended timestamps from Iurii Zaikin
In the future KUnit will be linked to Kselftest framework to provide
a way to trigger KUnit tests from user-space.

Expose in /sys/fs/f2fs/<blockdev>/main_blkaddr the block address where the
main area starts. This allows user mode programs to determine:
- That pinned files that are made exclusively of fully allocated 2MB
segments will never be unpinned by the file system.
- Where the main area starts. This is required by programs that want to
verify if a file is made exclusively of 2MB f2fs segments, the alignment
boundary for segments starts at this address. Testing for 2MB alignment
relative to the start of the device is incorrect, because for some
filesystems main_blkaddr is not at a 2MB boundary relative to the start
of the device.
The entry will be used when validating reliable pinning file feature proposed
by "f2fs: support aligned pinned file".

As presented at the 2018 Linux Plumbers conference [1], the Maintainer
Entry Profile (formerly Subsystem Profile) is proposed as a way to reduce
friction between committers and maintainers and encourage conversations
amongst maintainers about common best practices. While coding-style,
submit-checklist, and submitting-drivers lay out some common expectations
there remain local customs and maintainer preferences that vary by
subsystem.
The profile contains documentation of some of the common policy
questions a contributor might have that are local to the subsystem /
device-driver, special considerations for the subsystem, or other
guidelines that are otherwise not covered by the top-level process
documents.
The initial and hopefully non-controversial headings in the profile are:
Overview:
General introduction to how the subsystem operates
Submit Checklist Addendum:
Mechanical items that gate submission staging, or other requirements
that gate patch acceptance.
Key Cycle Dates:
- Last -rc for new feature submissions: Expected lead time for submissions
- Last -rc to merge features: Deadline for merge decisions
Resubmit Cadence: When and preferred method to follow up with the
maintainer
Note that coding style guidelines are explicitly left out of this list.
See Documentation/maintainer/maintainer-entry-profile.rst for more details,
and a follow-on example profile for the libnvdimm subsystem.

====================
This series extends RTNETLINK to provide IB port and node GUIDs, which
were configured for Infiniband VFs.
The functionality to set VF GUIDs already existed for a long time, and
here we are adding the missing "get" so that netlink will be symmetric and
various cloud orchestration tools will be able to manage such VFs more
naturally.
The iproute2 was extended too to present those GUIDs.

For example:
- ip link set ib4 vf 0 node_guid 22:44:33:00:33:11:00:33
- ip link set ib4 vf 0 port_guid 10:21:33:12:00:11:22:10

Rasmus correctly observed that the existing jobserver reservation only
worked if no other build targets were specified. The correct approach
is to hold the jobserver slots until sphinx has finished. To fix this,
the following changes are made:
- refactor (and rename) scripts/jobserver-exec to set an environment
variable for the maximally reserved jobserver slots and exec a
child, to release the slots on exit.
- create Documentation/scripts/parallel-wrapper.sh which examines both
$PARALLELISM and the detected "-jauto" logic from Documentation/Makefile
to decide sphinx's final -j argument.
- chain these together in Documentation/Makefile

The clock phase properties are having two uint32 values. The minItems
and maxItems are set to 2 for the same. So the property type should be
'uint32-array' and not 'uint32'. Modify it to correct the same.

Add sysfs attributes to Endpoints and other Upstream Ports to control ASPM,
Clock PM, and L1 PM Substates. The new attributes are:
/sys/devices/pci*/.../link/clkpm
/sys/devices/pci*/.../link/l0s_aspm
/sys/devices/pci*/.../link/l1_aspm
/sys/devices/pci*/.../link/l1_1_aspm
/sys/devices/pci*/.../link/l1_2_aspm
/sys/devices/pci*/.../link/l1_1_pcipm
/sys/devices/pci*/.../link/l1_2_pcipm
An attribute is only visible if both ends of the Link leading to the device
support the state. Writing y/1/on to the file enables the state; n/0/off
disables it.
These attributes can be used to tune the power/performance tradeoff for
individual devices.

Requests that triggers flushing volatile writeback cache to disk (barriers)
have significant effect to overall performance.
Block layer has sophisticated engine for combining several flush requests
into one. But there is no statistics for actual flushes executed by disk.
Requests which trigger flushes usually are barriers - zero-size writes.
This patch adds two iostat counters into /sys/class/block/$dev/stat and
/proc/diskstats - count of completed flush requests and their total time.

There is a config item CONFIG_SIMPLE_GPIO which
provides simple memory mapped GPIOs specific to powerpc.
However, the only platform which selects this option is
mpc5200, and this platform doesn't use it.
There are three boards calling simple_gpiochip_init(), but
as they don't select CONFIG_SIMPLE_GPIO, this is just a nop.
Simple_gpio is just redundant with the generic MMIO GPIO
driver which can be found in driver/gpio/ and selected via
CONFIG_GPIO_GENERIC_PLATFORM, so drop simple_gpio driver.

The main changes are:
1) Addition of BPF trampoline which works as a bridge between kernel functions,
BPF programs and other BPF programs along with two new use cases: i) fentry/fexit
BPF programs for tracing with practically zero overhead to call into BPF (as
opposed to k[ret]probes) and ii) attachment of the former to networking related
programs to see input/output of networking programs (covering xdpdump use case),
from Alexei Starovoitov.
2) BPF array map mmap support and use in libbpf for global data maps; also a big
batch of libbpf improvements, among others, support for reading bitfields in a
relocatable manner (via libbpf's CO-RE helper API), from Andrii Nakryiko.
3) Extend s390x JIT with usage of relative long jumps and loads in order to lift
the current 64/512k size limits on JITed BPF programs there, from Ilya Leoshkevich.
4) Add BPF audit support and emit messages upon successful prog load and unload in
order to have a timeline of events, from Daniel Borkmann and Jiri Olsa.
5) Extension to libbpf and xdpsock sample programs to demo the shared umem mode
(XDP_SHARED_UMEM) as well as RX-only and TX-only sockets, from Magnus Karlsson.
6) Several follow-up bug fixes for libbpf's auto-pinning code and a new API
call named bpf_get_link_xdp_info() for retrieving the full set of prog
IDs attached to XDP, from Toke Høiland-Jørgensen.
7) Add BTF support for array of int, array of struct and multidimensional arrays
and enable it for skb->cb[] access in kfree_skb test, from Martin KaFai Lau.
8) Fix AF_XDP by using the correct number of channels from ethtool, from Luigi Rizzo.
9) Two fixes for BPF selftest to get rid of a hang in test_tc_tunnel and to avoid
xdping to be run as standalone, from Jiri Benc.
10) Various BPF selftest fixes when run with latest LLVM trunk, from Yonghong Song.

The commit 0f27cff859 ("ACPI: sysfs: Make ACPI GPE mask kernel
parameter cover all GPEs") says:
"Use a bitmap of size 0xFF instead of a u64 for the GPE mask so 256
GPEs can be masked"
But the masking of GPE 0xFF it not supported and the check condition
"gpe > ACPI_MASKABLE_GPE_MAX" is not valid because the type of gpe is
u8.
So modify the macro ACPI_MASKABLE_GPE_MAX to 0x100, and drop the "gpe >
ACPI_MASKABLE_GPE_MAX" check. In addition, update the docs "Format" for
acpi_mask_gpe parameter.

It can be useful to delay setting the nowayout feature for a watchdog
device. Moreover, not every driver (notably gpio_wdt) implements a
nowayout module parameter/otherwise respects CONFIG_WATCHDOG_NOWAYOUT,
and modifying those drivers carries a risk of causing a regression for
someone who has two watchdog devices, sets CONFIG_WATCHDOG_NOWAYOUT
and somehow relies on the gpio_wdt driver being ignorant of
that (i.e., allowing one to gracefully close a gpio_wdt but not the
other watchdog in the system).
So instead, simply make the nowayout sysfs file writable. Obviously,
setting nowayout is a one-way street.

We have TI's glue layer for the Cadence USB3 controller going
upstream. Tegra's XUDC driver is also going upstream with this pull
request.
Apart from these two big features, we have a bunch of patches switching
over to devm_platform_ioremap_resource() in order to simplify code a
little; and a non-critical fix for DWC3 usage via kexec.

For MDS vulnerable processors with TSX support, enabling either MDS or
TAA mitigations will enable the use of VERW to flush internal processor
buffers at the right code path. IOW, they are either both mitigated
or both not. However, if the command line options are inconsistent,
the vulnerabilites sysfs files may not report the mitigation status
correctly.
For example, with only the "mds=off" option:
vulnerabilities/mds:Vulnerable; SMT vulnerable
vulnerabilities/tsx_async_abort:Mitigation: Clear CPU buffers; SMT vulnerable
The mds vulnerabilities file has wrong status in this case. Similarly,
the taa vulnerability file will be wrong with mds mitigation on, but
taa off.
Change taa_select_mitigation() to sync up the two mitigation status
and have them turned off if both "mds=off" and "tsx_async_abort=off"
are present.
Update documentation to emphasize the fact that both "mds=off" and
"tsx_async_abort=off" have to be specified together for processors that
are affected by both TAA and MDS to be effective.
[ bp: Massage and add kernel-parameters.txt change too. ]

Metadata runs are supposed to be aligned on 4k boundary (so that they work
efficiently with disks with 4k sectors). However, there was a programming
bug that makes them aligned on 128k boundary instead. The unused space is
wasted.
Fix this bug by providing a proper 4k alignment. In order to keep
existing volumes working, we introduce a new flag SB_FLAG_FIXED_PADDING
- when the flag is clear, we calculate the padding the old way. In order
to make sure that the old version cannot mount the volume created by the
new version, we increase superblock version to 4.
Also in order to not break with old integritysetup, we fix alignment
only if the parameter "fix_padding" is present when formatting the
device.

Now that we have the code to support encryption for subpage-sized
blocks, this commit removes the conditional check in filesystem mount
code.
The commit also changes the support statement in
Documentation/filesystems/fscrypt.rst to reflect the fact that
encryption on filesystems with blocksize less than page size now works.
[EB: Tested with 'gce-xfstests -c ext4/encrypt_1k -g auto', using the
new "encrypt_1k" config I created. All tests pass except for those that
already fail or are excluded with the encrypt or 1k configs, and 2 tests
that try to create 1023-byte symlinks which fails since encrypted
symlinks are limited to blocksize-3 bytes. Also ran the dedicated
encryption tests using 'kvm-xfstests -c ext4/1k -g encrypt'; all pass,
including the on-disk ciphertext verification tests.]

Schema errors can cause make to exit before useful information is
printed. This leaves developers wondering what's wrong. It can be
overcome passing '-k' to make, but that's not an obvious solution.
There's 2 scenarios where this happens.
When using DT_SCHEMA_FILES to validate with a single schema, any error
in the schema results in processed-schema.yaml being empty causing a
make error. The result is the specific errors in the schema are never
shown because processed-schema.yaml is the first target built. Simply
making processed-schema.yaml last in extra-y ensures the full schema
validation with detailed error messages happen first.
The 2nd problem is while schema errors are ignored for
processed-schema.yaml, full validation of the schema still runs in
parallel and any schema validation errors will still stop the build when
running validation of dts files. The fix is to not add the schema
examples to extra-y in this case. This means 'dtbs_check' is no longer a
superset of 'dt_binding_check'. Update the documentation to make this
clear.

There are both positive and negative options about this feature.
At first, I thought it was a good idea, but actually Linus stated a
negative opinion (https://lkml.org/lkml/2019/9/29/227). I admit it
is ugly and annoying.
The baseline I'd like to keep is the compile-test of uapi headers.
(Otherwise, kernel developers have no way to ensure the correctness
of the exported headers.)
I will maintain a small build rule in usr/include/Makefile.

- Allow ODR to be expressed more accurately by using miliHz.
* tools
- Fix an issue with parallel builds.
Cleanups and warning fixes
* adis16136, adis16400, adis16460, adis-lib
- Change some checks on return values to be for 0 rather than strictly
negative. Avoids some fiddly issues with the compiler concluding some
variables are initialized due to a mixture of error checks.
- Assign values only on success of 'read' operations - avoiding any
chance the compiler will falsly suggest they might be used uninitialized.
- Whitespace and simlar cleanups.

This means removing support for checking magic in amiserial.c
(SERIAL_PARANOIA_CHECK option), which was checking a magic field which
doesn't currently exist in the struct. That code hasn't built at least
since git.
Removing the definition from the header is safe anyway as that code was
from another driver and not including it.
