The rcu_nocb_poll kernel boot parameter is defined via early_param(), whose parsing functions are invoked from parse_early_param() which is in turn invoked by setup_arch(), which is very early indeed. It is invoked so early that the console output timestamps read 0.000000, in other words, before time begins. This use of early_param() means that the rcu_nocb_poll kernel boot parameter cannot usefully be embedded into the kernel image. Yes, you can embed it, but setup_boot_config() is invoked from start_kernel() too late for it to be parsed. But it makes no sense to parse this parameter so early. After all, it cannot do anything until the rcuog kthreads are created, which is long after rcu_init() time, let alone setup_boot_config() time. This commit therefore switches the rcu_nocb_poll kernel boot parameter from early_param() to __setup(), which allows boot-config parsing of this parameter, in turn allowing it to be embedded into the kernel image.

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.
