Email clients info for Linux
======================================================================
Git
----------------------------------------------------------------------
These days most developers use `git send-email` instead of regular
email clients. The man page for this is quite good. On the receiving
end, maintainers use `git am` to apply the patches.
If you are new to git then send your first patch to yourself. Save it
as raw text including all the headers. Run `git am raw_email.txt` and
then review the changelog with `git log`. When that works then send
the patch to the appropriate mailing list(s).
General Preferences

Patches for the Linux kernel are submitted via email, preferably as

The NTC thermistor is a simple thermistor that requires users to provide the
resistance and lookup the corresponding compensation table to get the

The NTC (Negative Temperature Coefficient) thermistor is a simple thermistor
that requires users to provide the resistance and lookup the corresponding
compensation table to get the temperature input.
The NTC driver provides lookup tables with a linear approximation function
and four circuit models with an option not to use any of the four models.

4.2 Notify memory hot-add event by hand
------------
On powerpc, the firmware does not notify a memory hotplug event to the kernel.
Therefore, "probe" interface is supported to notify the event to the kernel.
This interface depends on CONFIG_ARCH_MEMORY_PROBE.
CONFIG_ARCH_MEMORY_PROBE is supported on powerpc only. On x86, this config
option is disabled by default since ACPI notifies a memory hotplug event to
the kernel, which performs its hotplug operation as the result. Please
enable this option if you need the "probe" interface for testing purposes
on x86.
On some architectures, the firmware may not notify the kernel of a memory
hotplug event. Therefore, the memory "probe" interface is supported to
explicitly notify the kernel. This interface depends on
CONFIG_ARCH_MEMORY_PROBE and can be configured on powerpc, sh, and x86
if hotplug is supported, although for x86 this should be handled by ACPI
notification.
Probe interface is located at
/sys/devices/system/memory/probe
