__cpu_replace_ttbr1() is a static inline, and so it gets instantiated wherever it is used. This is not really necessary, as it is never called on a hot path. It also has the unfortunate side effect that the symbol idmap_cpu_replace_ttbr1 may never be referenced from kCFI enabled C code, and this means the type id symbol may not exist either. This will result in a build error once we start referring to this symbol from asm code as well. (Note that this problem only occurs when CnP, KAsan and suspend/resume are all disabled in the Kconfig but that is a valid config, if unusual). So let's just move it out of line so all callers will share the same implementation, which will reference idmap_cpu_replace_ttbr1 unconditionally.

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.
