On x86 set_pte_at() is now always falling back to set_pte(). So instead
of having this fallback after the paravirt maze just drop the
set_pte_at paravirt operation and let set_pte_at() use the set_pte()
function directly.

This driver adds support for the CTU CAN FD open-source IP core.
More documentation and core sources at project page
(https://gitlab.fel.cvut.cz/canbus/ctucanfd_ip_core).
The core integration to Xilinx Zynq system as platform driver
is available
This adds a devicetree for the Tolino Shine 2 HD Ebook reader. It is based
on boards marked with "37NB-E60QF0+4A2". It is equipped with an i.MX6SL
SoC.
Expected to work:
- Buttons
- Wifi
- Touchscreen
- LED
- uSD
- USB
- RTC
Not working due to missing drivers:
- Backlight (requires NTXEC driver)
This adds a device tree for the Tolino Shine 2 HD Ebook reader.
It is equipped with an i.MX6SL SoC. Except for backlight (via an EC) and
the EPD, drivers are available and therefore things are defined in the
dts.

On the older-gen 32-bit SoCs the meson-saradc driver is used to read the
SoC temperature. This requires reading calibration data from the eFuse.
Looking up the calibration data nvmem-cell requires the OF device_node
pointer to be available in the struct device which is passed to
Checking to see if this could fit in struct sock.
This goes against v5.8

Since the destination variable of the check_*_overflow() helpers will
contain a wrapped value on failure, it would be best to make sure callers
really did check the return result of the helper. Adjust the macros to use

During hotplug events, smt_mask would not contain all the CPUs in a core and
this can cause reassigning of rq->core, which breaks the core-wide counters
that are needed for tracking kernel-mode entry/exits.
This patch therefore makes sure that rq->core does not change once

By default, the lightbar commands are set to the
biggest lightbar command and response. That length is greater than 128
bytes and may not work on all machines.
But all EC are probed for lightbar by sending a get version request.
Set that request size precisely.

A test with the command below shows that the compatible string
"rockchip,rk3308-spdif", "rockchip,rk3328-spdif"
is already in use, but is not added to a document.
The current fallback string "rockchip,rk3328-spdif" points to a data

Ah yeah, good idea.
Use the standard FIELD_PREP() macro instead of << operator to perform
bitmask operations. This ensures type check safety and eliminate compiler
warnings.

LLVM implemented a recent "libcall optimization" that lowers calls to
`sprintf(dest, "%s", str)` where the return value is used to
`stpcpy(dest, str) - dest`. This generally avoids the machinery involved
in parsing format strings. Calling `sprintf` with overlapping arguments
was clarified in ISO

This command attaches the zero terminated string in optval to the
socket for troubleshooting purposes. The free string is displayed in the
process fdinfo file for that fd (/proc//fdinfo/).
One intended usage is to allow processes to self-document sockets
for netstat and friends to report
