Patch series "set clang minimum version to 10.0.1", v3. Adds a compile time #error to compiler-clang.h setting the effective minimum supported version to clang 10.0.1. A separate patch has already been picked up into the Documentation/ tree also confirming the version. Next are a series of reverts. One for 32b arm is a partial revert. Then Marco suggested fixes to KASAN docs. Finally, improve the warning for GCC too as per Kees. This patch (of 7): During Plumbers 2020, we voted to just support the latest release of Clang for now. Add a compile time check for this. We plan to remove workarounds for older versions now, which will break in subtle and not so subtle ways.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
