mainlining shenanigans
a788b2ed81
After cross-compiling the kernel, "make mrproper" should be executed with the proper ARCH= option. Otherwise, stale objects will remain under arch/$(SRCARCH)/. One bad scenario is like this: $ make ARCH=arm defconfig all # cross-compile the kernel for arm $ make mrproper # mrproper for host-arch (i.e. x86) $ make ARCH=arm O=build_dir defconfig all If you miss ARCH= for mrproper and cross-compile the kernel with O= and ARCH= options, Kbuild will happily start to build, but may fail due to stale objects in the srctree. If $(srctree)/arch/$(SRCARCH)/include/generated/ exists, let's stop the out-of-tree build. To detect this, mrproper should clean only arch/$(SRCARCH)/include/generated/.

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.
