setup_text_poke_area() is a late init call so it runs before mark_rodata_ro() and after the init calls. This lets all the init code patching simply write to their locations. In the future, kprobes is going to allocate its instruction pages RO which means they will need setup_text__poke_area() to have been already called for their code patching. However, init_kprobes() (which allocates and patches some instruction pages) is an early init call so it happens before setup_text__poke_area(). start_kernel() calls poking_init() before any of the init calls. On powerpc, poking_init() is currently a nop. setup_text_poke_area() relies on kernel virtual memory, cpu hotplug and per_cpu_areas being setup. setup_per_cpu_areas(), boot_cpu_hotplug_init() and mm_init() are called before poking_init(). Turn setup_text_poke_area() into poking_init().

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.
