selftests: settings: tests can be in subsubdirs
Commit 852c8cbf34d3 ("selftests/kselftest/runner.sh: Add 45 second
timeout per test") adds support for a new per-test-directory "settings"
file. But this only works for tests not in a sub-subdirectories, e.g.
- tools/testing/selftests/rtc (rtc) is OK,
- tools/testing/selftests/net/mptcp (net/mptcp) is not.
We have to increase the timeout for net/mptcp tests which are not
upstreamed yet but this fix is valid for other tests if they need to add
a "settings" file, see the full list with:
tools/testing/selftests/*/*/**/Makefile
Note that this patch changes the text header message printed at the end
of the execution but this text is modified only for the tests that are
in sub-subdirectories, e.g.
ok 1 selftests: net/mptcp: mptcp_connect.sh
Before we had:
ok 1 selftests: mptcp: mptcp_connect.sh
But showing the full target name is probably better, just in case a
subsubdir has the same name as another one in another subdirectory.

"The changes are a real mixed bag this time around.
The only scary looking one from the diffstat is the uapi change to
asm-generic/mman-common.h, but this has been acked by Arnd and is
actually just adding a pair of comments in an attempt to prevent
allocation of some PROT values which tend to get used for
arch-specific purposes. We'll be using them for Branch Target
Identification (a CFI-like hardening feature), which is currently
under review on the mailing list.
New architecture features:
- Support for Armv8.5 E0PD, which benefits KASLR in the same way as
KPTI but without the overhead. This allows KPTI to be disabled on
CPUs that are not affected by Meltdown, even is KASLR is enabled.
- Initial support for the Armv8.5 RNG instructions, which claim to
provide access to a high bandwidth, cryptographically secure
hardware random number generator. As well as exposing these to
userspace, we also use them as part of the KASLR seed and to seed
the crng once all CPUs have come online.
- Advertise a bunch of new instructions to userspace, including
support for Data Gathering Hint, Matrix Multiply and 16-bit
floating point.
Kexec:
- Cleanups in preparation for relocating with the MMU enabled
- Support for loading crash dump kernels with kexec_file_load()
Perf and PMU drivers:
- Cleanups and non-critical fixes for a couple of system PMU drivers
FPU-less (aka broken) CPU support:
- Considerable fixes to support CPUs without the FP/SIMD extensions,
including their presence in heterogeneous systems. Good luck
finding a 64-bit userspace that handles this.
Modern assembly function annotations:
- Start migrating our use of ENTRY() and ENDPROC() over to the
new-fangled SYM_{CODE,FUNC}_{START,END} macros, which are intended
to aid debuggers
Kbuild:
- Cleanup detection of LSE support in the assembler by introducing
'as-instr'
- Remove compressed Image files when building clean targets
IP checksumming:
- Implement optimised IPv4 checksumming routine when hardware offload
is not in use. An IPv6 version is in the works, pending testing.
- Work around some issues with Clang's integrated assembler not
liking our perfectly reasonable assembly code
- Avoid allocating the X18 register, so that it can be used to hold
the shadow call stack pointer in future
ACPI:
- Fix ID count checking in IORT code. This may regress broken
firmware that happened to work with the old implementation, in
which case we'll have to revert it and try something else
- Fix DAIF corruption on return from GHES handler with pseudo-NMIs
Miscellaneous:
- Whitelist some CPUs that are unaffected by Spectre-v2
- Reduce frequency of ASID rollover when KPTI is compiled in but
inactive
- Reserve a couple of arch-specific PROT flags that are already used
by Sparc and PowerPC and are planned for later use with BTI on

thermal: stm32: Fix low threshold interrupt flood
With the STM32 thermal peripheral, it is not possible to dump the
temperature that has caused the interrupt.
When the temperature reaches the low threshold, we generally read
a temperature that is a little bit higher than the low threshold.
This maybe due to sampling precision, and also because the CPU becomes
hotter when it quits WFI mode.
In that case, the framework does not change the trip points. This leads
to a lot of low threshold interrupts.
The fix is to set the low threshold value 0.5 degrees Celsius
below the actual request.
The problem is not so frequent with the high threshold and it would
no be a good idea to set the threshold value higher than the request.

When devm_thermal_zone_of_sensor_register() is called from

missing an OF node. In this case thermal_zone_of_sensor_register() returns
-EINVAL which causes hwmon_thermal_add_sensor() to fail as well. This patch

node devm_hwmon_device_register() returns error which ultimately causes

====================
qed*: Utilize FW 8.42.2.0
This FW contains several fixes and features, main ones listed below.
We have taken into consideration past comments on previous FW versions
that were uploaded and tried to separate this one to smaller patches to
ease review.
- RoCE
- SRIOV support
- Fixes in following flows:
- latency optimization flow for inline WQEs
- iwarp OOO packed DDPs flow
- tx-dif workaround calculations flow
- XRC-SRQ exceed cache num
- Debug
- Better handling of extracting data during traffic
- ILT Dump -> dumping host memory used by chip
- MDUMP -> collect debug data on system crash and extract after
reboot
Patches prefixed with FW 8.42.2.0 are required to work with binary
8.42.2.0 FW where as the rest are FW related but do not require the
binary.
Changes from V2
---------------
- Move FW version to the start of the series to maintain minimal compatibility
- Fix some kbuild errors:
- frame size larger than 1024 (Queue Manager patch - remove redundant
field from struct)
- sparse warning on endianity (Dmae patch fix - wrong use of __le32 for field
used only on host, should be u32)
- static should be used for some functions (Debug feature ilt and mdump)

octeontx2-pf: Add network driver for physical function

multiple physical and virtual functions. Each of the PF's
functionality is determined by what kind of resources are attached
to it. If NPA and NIX blocks are attached to a PF it can function
as a highly capable network device.
This patch series add a network driver for the PF. Initial set of
patches adds mailbox communication with admin function (RVU AF)
and configuration of queues. Followed by Rx and tx pkts NAPI
handler and then support for HW offloads like RSS, TSO, Rxhash etc.
Ethtool support to extract stats, config RSS, queue sizes, queue
count is also added.

net/core: Replace driver version to be kernel version
In order to stop useless driver version bumps and unify output
presented by ethtool -i, let's set default version string.
As Linus said in [1]: "Things are supposed to be backwards and
forwards compatible, because we don't accept breakage in user
space anyway. So versioning is pointless, and only causes
problems."
They cause problems when users start to see version changes
and expect specific set of features which will be different
for stable@, vanilla and distribution kernels.
Distribution kernels are based on some kernel version with extra
patches on top, for example, in RedHat world this "extra" is a lot
and for them your driver version say nothing. Users who run vanilla
kernels won't use driver version information too, because running
such kernels requires knowledge and understanding.
Another set of problems are related to difference in versioning scheme
and such doesn't allow to write meaningful automation which will work
sanely on all ethtool capable devices.
Before this change:
[leonro@erver ~]$ ethtool -i eth0
driver: virtio_net
version: 1.0.0
After this change and once ->version assignment will be deleted
