Make supports passing the 'jobserver' (parallel make support) to child invocations of make when either 1. The target command uses $(MAKE) directly 2. The command starts with '+' This context is not passed through expansions that result in $(MAKE), so the macros used in several places fail to pass on the jobserver context. Warnings are also raised by the child mentioning this. Prepend macros lines that invoke $(MAKE) with '+' to allow passing the jobserver context to these children.

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.
