No need to have one implementation of patch_instruction() for CONFIG_STRICT_KERNEL_RWX and one for !CONFIG_STRICT_KERNEL_RWX. In patch_instruction(), call raw_patch_instruction() when !CONFIG_STRICT_KERNEL_RWX. In poking_init(), bail out immediately, it will be equivalent to the weak default implementation. Everything else is declared static and will be discarded by GCC when !CONFIG_STRICT_KERNEL_RWX.

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.
