Attempting to build mach-rpc with gcc-9 or higher, or with any version of clang results in a build failure, like: arm-linux-gnueabi-gcc-11.1.0: error: unrecognized -march target: armv3m arm-linux-gnueabi-gcc-11.1.0: note: valid arguments are: armv4 armv4t armv5t armv5te armv5tej armv6 armv6j armv6k armv6z armv6kz armv6zk armv6t2 armv6-m armv6s-m armv7 armv7-a armv7ve armv7-r armv7-m armv7e-m armv8-a armv8.1-a armv8.2-a armv8.3-a armv8.4-a armv8.5-a armv8.6-a armv8-m.base armv8-m.main armv8-r armv8.1-m.main iwmmxt iwmmxt2; did you mean 'armv4'? Building with gcc-5 also fails in at least one of these ways: /tmp/cczZoCcv.s:68: Error: selected processor does not support `bx lr' in ARM mode drivers/tty/vt/vt_ioctl.c:958:1: internal compiler error: Segmentation fault Handle this in Kconfig so we don't run into this with randconfig builds, allowing only gcc-6 through gcc-8.

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.
