No portable code calls into this function any more, and on architectures that don't use or define their own, it causes a warning: kernel/iomem.c:10:22: warning: no previous prototype for 'ioremap_cache' [-Wmissing-prototypes] 10 | __weak void __iomem *ioremap_cache(resource_size_t offset, unsigned long size) Fold it into the only caller that uses it on architectures without the #define. Note that the fallback to ioremap is probably still wrong on those architectures, but this is what it's always done there.

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.
