There are two new events generated by dell-wmi, rfkill and fn-lock, from
Dell Systems.
When Fn-lock hotkey gets pressed to switch to function mode:
[85951.591542] dell_wmi: Unknown key with type 0x0010 and code 0xe035
pressed
[85951.591546] dell_wmi: Unknown key with type 0x0010 and code 0x0000
pressed
When Fn-lock hotkey gets pressed to switch to multimedia mode:
[85956.667686] dell_wmi: Unknown key with type 0x0010 and code 0xe035
pressed
[85956.667690] dell_wmi: Unknown key with type 0x0010 and code 0x0001
pressed
When radio hotkey gets pressed:
[85974.430220] dell_wmi: Unknown key with type 0x0010 and code 0xe008
pressed
These events are for notification purpose, so we can ignore them.
This patch is tested on XPS 9370.

This reverts commit e060d376cc61 ("mmc: renesas_sdhi: fix WP detection")
and adds some code to really fix the regressions.
It was missed so far that Renesas R-Car instantiations of SDHI chose to
disable internal WP and used the existence of "wp-gpios" to en/disable
WP at all.
With the first refactoring by Yamada-san with commit 2ad1db059b9a ("mmc:
renesas_sdhi: use MMC_CAP2_NO_WRITE_PROTECT instead of TMIO own flag"),
WP was always disabled even when GPIOs were present. With Wolfram's
first fix which gets now reverted, GPIOs were honored. But when not
available, the fallback was to internal WP and not to disabled WP. This
caused wrong WP status on uSD card slots.
Restore the old behaviour now. By default, WP is disabled. When a GPIO
is found, the GPIO re-enables WP. We will think about possible better
ways to handle this in the future.
Tested on a previously regressing Renesas Lager board (H2) and a still
working Renesas Salvator-X board (M3-W).

If the feature query fails during this driver's probe, we memset the
features bits to 0, but then we continue to overwrite that with whatever
junk we read back when the feature probing failed. In the case of a SPI
device, it may be complete junk, causing the caller of this function to
think certain features are present when they aren't. Don't copy over the
bad message on failure so we can fail more gracefully.

Intel Cannon Lake PCH has much higher 216 MHz input clock to LPSS I2C
than Sunrisepoint which uses 120 MHz. Preliminary information was that
both share the same clock rate but actual silicon implements elevated
rate for better support for 3.4 MHz high-speed I2C.
This incorrect input clock rate results too high I2C bus clock in case
ACPI doesn't provide tuned I2C timing parameters since I2C host
controller driver calculates them from input clock rate.
Fix this by using the correct rate. We still share the same 230 ns SDA
hold time value than Sunrisepoint.

As Google/Intel will fix the BIOS/Coreboot issues with hardcoding
virtual interrupt numbers for keyboard/touchpad/touchscreen controllers
in ACPI tables, they will also update BOARD version number from 1.0
to 1.1. Let's limit the DMI quirks that try to preserve virtual IRQ
numbers on Strago boards to those that still carry older BIOSes.
Note that ideally not BOARD but BIOS version should have been updated.
However the BIOS version used by Chrome devices has format of
Google_BUILD.BRANCH.PATCH which is not well suited for DMI matching as
we do not have "less than" match mode for DMI data.

Yonghong Song says:
====================
bpf has been used extensively for tracing. For example, bcc
contains an almost full set of bpf-based tools to trace kernel
and user functions/events. Most tracing tools are currently
either filtered based on pid or system-wide.
Containers have been used quite extensively in industry and
cgroup is often used together to provide resource isolation
and protection. Several processes may run inside the same
container. It is often desirable to get container-level tracing
results as well, e.g. syscall count, function count, I/O
activity, etc.
This patch implements a new helper, bpf_get_current_cgroup_id(),
which will return cgroup id based on the cgroup within which
the current task is running.
Patch #1 implements the new helper in the kernel.
Patch #2 syncs the uapi bpf.h header and helper between tools
and kernel.
Patch #3 shows how to get the same cgroup id in user space,
so a filter or policy could be configgured in the bpf program
based on current task cgroup.
Changelog:
v1 -> v2:
. rebase to resolve merge conflict with latest bpf-next.
